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, tem-
perature, 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
Providing for both a voltage trip and a current trip function in
a magnetic circuit protector is common practice. These two
coil protectors provide remote or automatic opening of one or
more circuits with a low level signal.
The voltage coil will trip the protector instantaneously while
the current coil provides normal inverse time delays. The volt-
age coil is not rated for continuous duty and therefore, the
voltage must be removed when the breaker trips.
Since both coils are housed within the same pole, the space
savings are substantial.
This option is not available with 64, 65 or 66 delays.
Shunt Trip
The shunt trip is designed for controlling two separate loads with
one assembly. The control is established by providing overload
protection for the critical load. When the current through this
load becomes excessive and reaches the trip point, the protector
will open and remove power from both loads simultaneously. The
total current rating of both loads must not exceed the maximum
contact rating.
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 configura-
tion is becoming increasingly more important for sensitive
circuitry and denser packaging in automation systems.
Available in series, shunt or relay configurations.
