Control Units
Overcurrent Trip Switch (SDE)
Delivered standard with control unit. In addition to the fault trip indicator/reset button, one SPDT
switch provides alarm/lockout information. This SPDT switch is operated only when the circuit
breaker is tripped by the control unit. When the circuit breaker is reset, the "a" switch (alarm) is
open and the "b" switch (lockout) is closed.
Output Characteristics SPDT 10 A/240 Vac
Power Supply Not Required

Segregated Trip Switch (FV)
This switch works exactly as the standard overcurrent trip switch (SDE) except that a commutator
on the front face is used to choose the type of fault which will operate the contact: overload, short-
circuit, ground-fault, or any combination of these types. This option can be used in addition to the
SDE switch for remote signalization of particular types of faults. A flat push button allows resetting of
the indicator after tripping.
Output Characteristics 5 A/240 Vac
Power Supply Required
Wired in parallel with the remote opening button which operates the shunt trip, the option FV
contact provides an electrical interlock which prevents the circuit breaker from being closed after the
pre-selected type of faults: for example the circuit breaker will be able to be remotely closed after
overload, but not after short circuit.
