Siemens 5SJ4104-7HG41 Circuit Breaker

Siemens 5SJ4104-7HG41 is a SENTRON miniature circuit breaker (MCB) designed to protect a single electrical circuit from overloads and short circuits, rated for 240 V AC with a 14 kA interrupting capacity, and it integrates a compact 1-pole, 4 A rating for space‑efficient panel installations. It uses a Type C tripping curve, providing moderate response for general‑purpose protection of small branch circuits in residential or light commercial panels, and it carries UL 489 listing to meet common electrical-safety standards. This variant belongs to the 5SJ4 family, with the 7HG41 suffix identifying the exact configuration; the datasheet notes a depth of about 70 mm, emphasizing its compact footprint for modular enclosures. As a Siemens SENTRON product, it is specified for 14 kA at 240 V and is commonly used in distribution boards and consumer units where reliable overcurrent protection is required for low‑current loads.
