Siemens 5SJ4111-7HG41 Mcb 1 Pole 240V

Product Description

The SIEMENS 5SJ4111-7HG41 is a miniature circuit breaker (MCB) from the 5SJ4 series, designed to provide overcurrent and short-circuit protection in low-voltage electrical distribution systems. This single-pole breaker operates at 240 volts and weighs 0.375 pounds, making it a compact yet reliable protective device. Licensed electricians install this type of MCB in panelboards, distribution boards, and control panels across residential and light commercial applications. Its din-rail mount form factor keeps installation straightforward and consistent with standard panel layouts.

This MCB is suited for single-pole branch circuit protection in 240-volt systems. It fits into electrical distribution panels and enclosures where space-efficient overcurrent protection is required. Typical installation scenarios include commercial control panels, light industrial distribution boards, and residential sub-panels. Its compact footprint, measuring 4.488 inches long by 0.906 inches wide by 3.307 inches high, allows it to fit into tight panel configurations without sacrificing protection reliability.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and local codes. Always de-energize the panel and verify zero voltage with a meter before handling or replacing any circuit breaker. Ensure the DIN rail is properly grounded and that the breaker snaps fully and securely into position before restoring power. Do not exceed the breaker rated voltage or attempt to use this device as a disconnect without confirming its suitability for that application.
