UL 489 recognition confirms its suitability for single‑phase circuits in commercial and industrial panels, making it a common choice for protecting 277 V lighting runs and general distribution loads. The device is built for insulation up to 440 V (Ui) and, in many listings, is described with a compact 1‑pole form factor that suits standard panel installations where space is at a premium. With its 70 mm installation depth, this 5SJ4‑series breaker offers a compact, dependable solution within Siemens’ line for applications requiring precise current limitation at a 6 A rating, while maintaining coordination with other protective devices in the same panel. As a Siemens part, 5SJ4106-7HG42 aligns with widely used DIN‑rail panel architectures and replacement practices for 277 V circuits, delivering predictable tripping behavior and robust fault interruption in protection schemes where a single‑pole 6 A device is specified. \u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268031107306,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-016.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-5sj4106-7hg42-single-pole-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
