The PL7 miniature circuit breaker (MCB) is a protective device that is 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 PL7 devices for DC applications are available with rated currents from 1 A to 50 A and can withstand rated voltages up to 250 V DC. The switching capacity is 10 kA. The circuit breaker, which is available with tripping characteristic C, is equipped with a red-green contact-position indicator for indicating the device state: green means that the contacts are open, and red that they are closed.
