DC String Circuit Breakers PKZ-SOL

The fuseless alternative for protection against short circuit currents with the string circuit breaker PKZ-SOL. With their variable trip range, they can be optimally adjusted to the actual short-circuit current of a string. A thermal release reacts at 1.05 … 1.3 fold current, and the magnetic release at 6-fold current. Non-enclosed string circuit breakers are intended for installation in customized generator connection enclosures.
