Series CA8 Contactors andCAT8 Starters

An ingenious miniature contactor and starter system

Sprecher + Schuh’s New CA8 Series of miniature contactors and starters provide an extremely compact and reliable method of controlling motors of 7.5 HP or less (@460V). The CA8 is an economical choice for applica-tions where space is limited or where a minimal enclosure is desired.

Small but ruggedEven though their contacts and coils are not replaceable, Sprecher + Schuh has subjected this series of contactors to monitored endurance tests that demonstrate their ruggedness. At full load, under 3-phase power, the con-tacts in the CA8 have an electrical life of 700,000 operations, while the AC magnet system has a mechanical life of 15,000,000 operations.

The CAT8 Starter – Efficient and reliableThis miniature starter features the new CT8 Thermal Overload Relay. A com-plex current limiting calibration proce-dure performed after each unit is what ensures the consistent high quality of Sprecher + Schuh’s thermal overload relay. Today’s, Class 10 T-frame design like the CT Series has been recognized by many motor manufacturers as the ideal type to assure optimum motor protection due to less use of copper and iron.

Accessories require no additional panel spaceThe entire CA8 System is logically engineered. Modular accessories like auxiliary contact blocks snap-on without increasing the CA8’s origi-nal width of 45mm. Also, due to its horizontal switching movement, the basic contactor has the same low profile whether an AC or DC operat-ing magnet is used. This permits the

use of enclosures with shallow mount-ing depths. Once the CA8 is installed, all auxiliary contact blocks can be snapped-on or removed without changing any existing power wiring. Other accessories include a snap-on RC Link (surge suppressor), mechani-cal interlocks and space saving adap-tors for connecting auxiliary compo-nents.

Effortless installationBoth the CA8 Contactor and the CAT8 Starter are DIN-rail mountable for instant installation and modifica-tion. Fittings are also included on the CA8 for base mounting. All terminals are clearly marked and shipped in the open position for installation with either manual or power screwdrivers.

Catalog Number CodingSprecher+Schuh employs a catalog number coding system for contactors (and many other devices) that follows a logical pattern, where every digit signifies a specific device attribute. Where indicated, the use of dashes (–) serves to separate device characteristics and should always be used when ordering.

The following example illustrates all of the possible combi-nations when specifying contactors and reversing contactors (open type only).

Determining Contact LifeTo determine the contactor’s estimated electrical life, follow these guidelines:1. Identify the appropriate Utilization Category from Table A.2. On the following pages, choose the graph for the Utilization Cat-

egory selected.

Table A – IEC Special Utilization Categories, AC Ratings

Utilization categories and test conditions for AC & DC. For contactors according to IEC 158-1, starters according to IEC 292-1 ... 4 and control switches according to IEC 337-1 and IEC 337-1A.With a minimum value of 1000A for I or Ic.With a minimum value of 800A for Ic.With a minimum value of 1200A for I.Plugging is understood as stopping or reversing the motor rapidly by reversing the motor primary connections while the motor is running. Inching [or jogging] is understood as energizing a motor once or repeatedly for short periods to obtain small movements of the driven mechanism.

3. Locate the Rated Operational Current (le) along the bottom of the chart and follow the graph lines up to the intersection of the ap-propriate contactor’s life-load curve.

4. Read the estimated contact life along the vertical axis.

Simple and effectivemotor protectionfor applications to71/2HP@ 460V(10HP@575V)

Sprecher + Schuh has been a leader inproviding superior motor protection.The new CT8 is an economical ther-mal overload relay yet includes provenfeatures like “Differential tripping”,Automatic / Manual reset modes,and isolated alarm circuit contacts asstandards.

Consistent and reliableprotectionThe consistent high quality of Sprecher + Schuh thermal overloadrelays is ensured by a complex currentcalibration procedure performed aftereach unit is at full operating tempera-ture. Calibration is performed at thelargest and smallest current the over-load can handle. The accurate time/current characteristic curve obtained inthis manner guarantees reliable motorprotection every time.

Superior Class 10characteristicsToday’s T-Frame motors have lesscopper and iron that the old U-Framemotors that were popular whentraditional Class 20 overload relayswere designed. For this reason, fasterClass 10 overloads like the CT8 Serieshave been recognized by many motormanufacturers as the ideal type to assure optimum protection of “T”frame motors.

Protection from singlephase conditionsA unique feature not found in tradi-tional thermal overload relays providesaccelerated tripping under single phaseconditions. This is accomplished witha special “differential tripping” mecha-nism built into CT8 (see illustration atright).

Ambient temperaturecompensationAll Sprecher + Schuh thermal overloadrelays are temperature compensated.An additional bimetallic ambient com-pensation strip, built into the conduc-tor-bimetal transmission path, ensuresthat the tripping characteristics of therelay remain constant over an ambienttemperature range of –25°C to +50°C.

Single phase applicationsCT8 Series thermal overload relayscan be applied for protection of singlephase AC motors. The relays have thesame characteristics as shown for threephase operation. To maintain thesecharacteristics, each element of theoverload relay must carry the motorcurrent as shown in the schematic onpage C88.

Other standard featuresCT8 thermal overload relays feature a fail-safe “trip-free” design that preventsthe device from being held closed dur-ing an overload. In addition, a select-able lever permits the user the optionto choose the manual or automaticreset modes.

A separate NO signal contact is alsoprovided on CT8 overloads which isisolated from the NC trip contact.This permits the use of a trip signalvoltage different than that of the con-trol voltage.

Despite increasing complexity, control systems and installations must become increasingly compact. And the CS8 Miniature Relay System packs maximum performance into minimum space.

Small but ruggedSprecher + Schuh has subjected this relay series to monitored endurance tests that demonstrate their ruggedness. Under normal duty, CS8 contacts have an electrical life of 700,000 operations, while the AC magnet system has a me-chanical life of 15,000,000 operations.

The coil is designed for absolute under-voltage reliability. Undervoltages that do not cause the contactor to close can be withstood indefinitely without damage.

The body of the device is sturdy as well. The front housing, containing the phase partitions and screwdriver guides, is manufactured in one piece. Front and rear housing are then joint fitted together.

Superior Contact ReliabilityThe standard CS8 base relay and aux-iliary contacts are bifurcated H-bridge design which divides each movable con-tact into two sections at the tip of the spanner which provides a higher degree of reliability for low signal applications. Perfect fit for PLC and other electronic circuits operate at signals as low as 15V @ 2mA.

Accessories require no additional panel spaceThe entire CS8 system is logically engineered. Auxiliary contact blocks are modular and snap-on without increas-ing the CS8’s original width of 45mm. Also, due to its sideways switching movement, the basic relay has the same low profile whether an AC or DC oper-ating magnet is used. This permits the use of enclosures with shallow mount-ing depths. Once the CS8 is installed,

CS8 front mount auxiliaries are positive guidance

CS8IndustrialControlRelays

The miniature relay system with big advantages

all auxiliary contact blocks can be snapped on or removed without chang-ing any existing wiring.

Auxiliary components provide flexibilityCS8 auxiliary components allow you to convert the basic four pole relay up to an 8 pole relay.

Effortless installationCS8 relays are DIN-rail mountable for instant installation and modifica-tion. Fittings are also included for base mounting. All terminals are clearly marked and shipped in the open posi-tion for installation with either manual or power screwdrivers. Using self-adhe-sive labels, or plastic clip-on tags.

The entire line is cULus Listed and CE Certified and offers finger and back of hand protection to the strictest interna-tional standards.
