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.
