Siemens 5SJ4106-7HG41 Industrial Circuit Breaker

Siemens 5SJ4106-7HG41 is a one-pole Sentron miniature circuit breaker (MCB) rated for 240 V AC with a 6 A nominal current and a C-type thermal-magnetic trip, designed to protect a single branch circuit from overloads and short circuits within electrical panels, enclosures, and control gear; this model is part of the 5SJ4 family, known for compact, modular protection in low-voltage installations. It provides a short-circuit interruption capacity of 14 kA at 240 V, and the unit’s mounting depth is 70 mm (D = 70 mm), aligning with UL 489 configurations for standard panel installations. This device is intended for use in standard distribution panels and enclosures to safeguard low-voltage circuits from faults, offering reliable, field-reliable protection with a dedicated single-circuit focus. The combination of a thermal-magnetic trip and a 14 kA interrupt rating supports protection for circuits with moderate fault currents, making the 5SJ4106-7HG41 a precise, single-circuit protection solution within Siemens’ Sentron portfolio.
