Electrical Closing Push Button (BPFE)
Located on the front panel of the circuit breaker, this push
button carries out electrical closing of the circuit breaker,
taking into account all of the safety functions that are part
of the control/monitoring system of the installation. The
push button is installed on the control circuit of the shunt
close, and connects to the communicating shunt close
module (XF-COM). Terminal A2 of XF-COM is used to
remotely close the circuit breaker.
Remote Reset (RES) and Automatic Reset After Fault Trip
•
Following tripping, the remote reset (RES) resets the overcurrent trip switch (SDE) and the
mechanical indicator. (Voltage rating: 110/130 Vac and 200/240 Vac.) RES is not compatible with
an additional overcurrent trip switch (SDE2).
• Automatic reset after fault-trip: following tripping, a reset of the mechanical indicator (reset button)
is no longer required to enable circuit breaker closing (factory adjustable only).
Switches and Switch Accessories
Auxiliary Switch (OF)
The rotary-type auxiliary
switches are directly driven by
the trip mechanism when the
minimum isolation distance
between the main circuit
breaker contact is reached.
