Undervoltage Release
Mechanism
70 and 35 percent of the solenoid
coil rating.
The undervoltage release mechanism
consists of a continuous rated sole-
noid with a plunger and tripping lever
mounted in a plug-in module. The tab
on the tripping lever resets the under-
voltage release mechanism when
normal voltage has been restored and
the circuit breaker handle is moved to
the reset (or OFF) position. With less
than pickup voltage applied to the
undervoltage release mechanism, the
circuit breaker contacts will not touch
when a closing operation is attempted.
Note: Undervoltage release mechanism
accessories are not designed for, and
should not be used as, circuit interlocks.
Ordering Information
Select handle reset undervoltage
release mechanism catalog number
for the voltage within the indicated
voltage range. Undervoltage release
mechanism coils are designed to be
applied at specific ac or dc voltages
within the voltage range shown on
applicable circuit breaker accessory
nameplates.

Undervoltage Release Mechanism
UV
The Undervoltage Release
Mechanism monitors a
voltage (typically a line
voltage) and trips the
circuit breaker when the
voltage falls to between
