Tripping
Tripping indication on front panel by means of a red indicator.

Auxiliaries conforme standard IEC 60947-1
MX + OF shunt trip release
Controls tripping of the device with which it is combined when energised.
It is fitted out with a changeover contact (O + C) to indicate the circuit-breaker’s
position.
It is fitted with a self-interrupting contact allowing the control circuit to remain on
(latching emergency stop).
MX shunt release
Controls tripping of the device with which it is combined at power-up.
It is fitted with a self-interrupting contact allowing the control circuit to remain on
(latching emergency stop).
MN release
Controls tripping of the device with which it is combined when its supply voltage
drops (threshold between 70 and 35 % of the Un).
It allows the device to be manually closed if the voltage exceeds 85 % of the
nominal voltage.
n
Use:
Emergency stop pushbutton
Safety on supply circuits of several machines by preventing the
“non-controlled” restart of all the motors
MN selective s release
Undervoltage release that controls the opening of the device with which it is
combined.
0.3 s time-delay on voltage dip: avoids tripping on brownouts or momentary
voltage drops.
MNx release for pushbutton with opening
Completely insensitive to supply circuit interruptions.
It is recommended to connect it upstream of the circuit-breaker it protects in the
event of fail-safe emergency stops.
MSU voltage threshold release
Especially designed to monitor the voltage between the neutral and phase(s)
conductors.
It cuts off the supply by opening the protected device when a threshold level for
overvoltages lasting more than a few tenths of a second is exceeded.
