The PLS6 miniature circuit breaker (MCB) is a protective device that's equipped with both a thermal and an electromagnetic release. The former responds in the event of an overload, while the latter offers protection against short circuits. The 1- and 2-pole PLS6 devices for DC applications are available with rated currents from 1 A to 50 A and can withstand rated voltages of up to 250 V DC.
