4-channel and 8-channel electronic circuit breakers | PISA 11 and PISA-B 4-channel and 8-channel electronic circuit breakers | PISA 11 and PISA-B

Electronic circuit breakers

The PISA multi-channel electronic circuit breakers with DIN rail mounting are designed for current distribution and protection of DC 24 V load circuits.

The PISA electronic circuit breakers distribute the current of large power sources to multiple lower current output channels and therefore allow for smaller wires to be used.

In the event of a fault, the electronic circuit breaker reliably switches off the channels and protects the loads.

Compact 4 channel ECBs: PISA-M

8 channel ECBs: PISA-B
