Relay Trip

Dual Coil

Voltage Trip

Optional Barriers (IEG Only)

This permits the overload sensing coil to be placed in a circuit which is electrically isolated from the trip contacts. The coil may be actuated by sensors

monitoring pressure, flow, temperature, speed, etc. Other typical applications include crowbar, interlock and emergency /rapid shutdown circuitry. Trip

may be accomplished by voltage or current, which must be removed after trip.

By combining two electrically independent coils on a common magnetic circuit, it is possible to provide contact opening when either an over-current or

trip voltage is applied to the respective coils. One coil will be a current trip coil with standard specifications. The second, or dual coil, can be used to

provide a control function permitting contact opening from a remote interlock or other transducer functions. Standard coils are 6, 12, 24, 48, 120 and

240 volts. Tripping is instantaneous and must be removed (usually self-interrupting) after trip.

Sometimes called “dump circuits” or “panic trip circuits,” these units make it possible to open main power contacts with lower power inputs from

one or more sources. This configuration is becoming increasingly more important for sensitive circuitry and denser packaging in automation systems.

Available in series, shunt or relay configurations.
