Electro-mechanical trip device (Undervoltage release)

Order code: V350
Ordering data: Operating voltage and frequency for the magnetic system
Available for: All cam-switches of size S1
Max. ambient temperature open: 35°C during 24 hours with peaks up to 40°C

The device includes a magnetic system which releases the switch to the trip position at voltage failure of 70% of the nominal voltage.
The device is trip-free, in that the switch can be operated only when the primary voltage is available.
For switches in size S0 please choose a 'Power failure release'.
Available switch detents: 1x60°, 1x90° ('ON'-position 60° or 90° clockwise of the 'OFF'-position; Trip-position 120° clockwise of the 'OFF'-position)
If used with DC an economy resistor must be provided.
