Siemens 5SJ4102-7HG41 Mcb 1 Pole 240V

Product Description

The SIEMENS 5SJ4102-7HG41 is a single-pole miniature circuit breaker (MCB) from the 5SJ4 series, rated for 240 volts. Miniature circuit breakers provide overcurrent protection by automatically interrupting the circuit when current exceeds the rated threshold, protecting wiring and connected equipment from damage. This unit is designed for installation in residential, light commercial, and industrial distribution panels where compact, reliable branch circuit protection is required. Licensed electricians typically install and service this type of protective device in accordance with applicable electrical codes.

The 5SJ4102-7HG41 is suited for single-pole branch circuit applications in 240-volt distribution systems. It fits within the 5SJ4 product family, which is a DIN rail-mounted MCB series commonly found in load centers and control panels across residential and light commercial installations. Its compact footprint makes it appropriate for space-constrained enclosures where standard thermal-magnetic trip protection is needed.

Installation Notes

Installation should be performed by a licensed electrician in compliance with the National Electrical Code (NEC) and all applicable local codes. Always de-energize and lock out the distribution panel before installing or replacing a circuit breaker. Verify that the bus voltage, pole configuration, and interrupting rating are appropriate for the target circuit before installation. Do not exceed the rated voltage or current capacity of the device.
