That 15 kA IEC rating gives you headroom on SCCR coordination in industrial panels — the 10 kA EN figure covers residential/commercial branch circuits, while the 15 kA IEC figure is what matters for the industrial plant-floor install. ## DIN-rail fit and panel fill Snaps onto standard mounting rail (EN 60715) in any orientation — vertical, horizontal, upside down, doesn't matter. At 36 mm wide (2 modular units) and 70 mm deep, it fits a standard distribution board or industrial enclosure without protruding past the gland plate. IP20 with conductors connected, IP40 in the handle area — fine for enclosed panels, not for washdown zones. Current production — no phase-out notice on this code. The 5SJ4 platform is Siemens' established miniature breaker line, and this 2-pole C-curve variant is a standard catalog item. For BOM-line commitment, the 10 kA / 15 kA interrupting ratings and 400 V AC / 60 V DC voltage ratings are the numbers that lock the fit. Sealable design allows lockout/tagout in safety circuits. Vibration rated at 50 m/s² (25–150 Hz) and 60 m/s² at 35 Hz for 4 seconds — holds up on a machine frame or conveyor line.","metaTitle":"Siemens 5SJ4202-7HG41 SENTRON MCB, 2-pole C-curve, 10 kA","metaDescription":"Siemens 5SJ4202-7HG41 SENTRON miniature circuit breaker. 2-pole, C-curve, 10 kA per EN 60898, 15 kA per IEC 60947-2. 400 V AC / 60 V DC.

The 5SJ4202-7HG41 is a C-curve unit; the 5SY4140-7 is a different characteristic. Verify the trip curve and SCCR requirements of your existing panel design before swapping — the physical mount is the same, but the protection coordination may differ."},{"question":"Where can I buy the 5SJ4202-7HG41 and how is it quoted?","answer":"Sourced and quoted to order through independent distribution against an RFQ.
