Earth Leakage Circuit Breaker

Typical Earth Leakage Circuit Breaker

Product DescriptionSeries C Earth Leakage Breakers offer superior Class 1 ground fault protection and improved ground fault coordina-tion capability.

Earth leakage ground fault protection differs from other types of systems in its level of sensitivity. The sensitivity of traditional devices is limited by the cumulative error of the residual current sensors and the placement of the phase and neutral conductors inside the current sensor.

Leakage breakers are zero sequence sensing devices. They are factory sup-plied with a single sensor and ground fault relay built-in. This technique allows for protection sensitivities down to the 30 milliampere level.

Leakage breakers are provided with a full complement of easy adjustments. The ground fault pickup setting is adjustable from 0.03 to 30 amperes in eight steps, and the ground fault time delay setting is adjustable from instantaneous to 2.0 seconds in six steps. When the pickup is set to 30 mA, the time delay setting defaults internally to instantaneous only. Increased selectivity provides for improved coordination with upstream and downstream ground fault devices as well as the flexibility to adjust for transient currents.

Application DescriptionThree-Phase, Four-Wire LoadsFor three-phase applications with line-to-neutral loads, select 4-pole earth leakage breakers and wire the neutral through the fourth (right) pole.

Three-Phase, Three-Wire LoadsFor applications with only three-phase, three-wire, line-to-line connected loads, select 3-pole earth leakage breakers.

Single-Phase LoadsFor single-phase, two-wire or three-wire applications, use a 3-pole earth leakage breaker and connect all conductors through the breaker.

GeneralDo not reverse feed. Do not apply on 400 Hz systems.

Options and AccessoriesOptional Factory Installed Internal AccessoriesEarth leakage breakers use the same internal accessories as standard F-, J- and K-Frame Series C Breakers. Internal accessories fit in the right-hand pole space and are available as factory modifications only.

Bell alarm is included as standard.

Optional External AccessoriesSeries C Earth Leakage Breakers use the same external accessories as the standard F-, J- and K-Frame circuit breakers. R.H. only.
