Shunt Trip
-
-
Allows remote tripping of the associated device, operation of the coil is indicated by a flag on the front of the device.
Under Voltage Release
-
-
Allows RCCB to be closed, only when voltage is above 85% of U n . RCCB will automatically trip when voltage falls to
between 70-35% of U n (230V). Operation of the release is indicated by a flag on the front of the device.

4mm² flexible, 6mm² rigid
Shunt Trip:
Allows remote tripping of devices. Operation of the coil is indicated by a flag on the front of the device.
Under Voltage Release:
Allows MCB to be closed only when voltage is above 85% of U n . MCB will automatically trip when
voltage falls to between 70-35% of U n . Operation of the coil is indicated by a flag on the front of the device.
