Protection for solar panels with fireman's switch

These modular protectors are located at a larger plant in Gothenburg. The picture shows 3 PV modules protection with 60A fireman's switch, surge protectors and fuses to protect the solar cell panels.

The fireman's switch allows the emergency services to disconnect cables between the solar panels and the inverter in the event of a fire.

The fireman's switch is operated with actuators placed at the fire alarm center.
