Start Inhibit

The start inhibit function prevents the

starting of a motor when the motor is too

hot and does not have a sufficient amount

of thermal capacity available to allow a

start without being tripped offline.

Breaker Failure Protection

The breaker failure protection element

monitors for timely operation of the

connected breaker. If a trip command is

not successful in operating the breaker

and clearing the fault, the breaker failure

element can be used to send trip signals to

upstream breakers to clear the fault.

Undercurrent Protection

The undercurrent protection element

provides the ability to trip the motor due

to external conditions that can cause the

load being pulled by the motor to drop

below a preset level.  This element is useful

when the loss of the load results in a loss

of cooling which will cause the asset to

overheat.
