Relay Trip

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.

Dual Coil

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.

Voltage 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.
