Joslyn Clark, the Motor Control Specialists,
vacuum Contactors for heavy industrial applica-
Vacuum Contactors enclose the power contacts within a vacuum chamber. This sophisticated technology results in the following advantages.
analytical testing. Specially selected materials are used such as high alumina ceramics for high temperature processing and degassing. Contact materials are selected for transient voltage generation control.
interrupters are tested mechanically and electrically to ensure vacuum integrity. All interrupters are held for a period of time and retested before being installed in contactors and shipped to the customer.

The control module contains the coil and auxiliary contacts wired to a terminal block and is easily removed for checking or immediate replacement. The phase assembly and the control module are the only two replacement parts. The phase assem-bly is a vacuum interrupter containing the power switching contacts.

automatic grounding arm. The switch is provided with a viewing window mounted in the fixed mounted panel allowing for a visible check that the switch has been opened and the blades grounded. The disconnect switch is interlocked with the front medium voltage access door to ensure access to the medium voltage compartment can only be achieved when the switch has been opened and the blades grounded.
Isolation between the load break disconnect switch compartment, the medium voltage compartment and grounded metal isolation between the low voltage and medium voltage compartments.
preventing the risk of single phasing in the event of one single fuse blowing.
bimetal ambient compensated overload relay mounted in the low voltage compartment, heater elements are fitted. The relay is manually reset via low voltage compartment.
The low voltage fuse will be mounted in the low voltage compartment. The two high voltage primary fuses will be mounted in the medium voltage compartment.
The above starters can be provided and are suitable for reversing applications whereby this specification remains

These starters are also available in the reversing arrangement for reversing applications. The specification will be exactly as above for that medium voltage reduced voltage auto-transformers starters with the addition of two medium voltage contactors with two normally opened, two normally closed auxiliary contacts and mechanical interlock on the forward and reverse contactors.
