PKZ-SOL20

Eaton Moeller® series PKZ-SOL String circuit-breaker, DC current, 2p, 20A

String circuit-breakers PKZ-SOL are the fuseless alternative for the protection of photovoltaic modules against short-circuit currents. With their variable tripping range, they can be optimally adjusted to the actual short-circuit current of a string. Using the optional delayed undervoltage release P-SOL-XUV, remote switching, for example, for the fire brigade is possible.
