The PISA product family includes electronic circuit breakers with 4-channels and 8-channels. The PISA product family includes electronic circuit breakers with 4-channels and 8-channels.

PISA

The PISA product family includes all electronic circuit breakers which are designed and manufactured by PULS.

The compact supplementary units distribute the current in an application, protect DC 24V load circuits from over-current or short-circuits and monitor the operating status in DC 24V systems. All devices can be mounted easily on a DIN rail.

PISA is the short form for Protect Inform Secure Assist, which shows the intended use of these devices.
