That 10 kA rating means it safely clears a fault up to 10,000 amps without welding its contacts or letting the arc escape, which is the standard you need for a residential or light-commercial distribution board. IP20 with conductors connected, which is fine inside a closed panel; keep it out of washdown zones. Rated for any mounting position, and the -40 °C to 75 °C operating range means it lives in an unheated enclosure or a hot switchroom without derating.","metaTitle":"Siemens 5SL4250-7RC SENTRON MCB, 2P C-curve 50 A 10 kA","metaDescription":"Siemens 5SL4250-7RC SENTRON miniature circuit breaker, 2-pole C-curve 50 A, 10 kA breaking capacity per EN 60898.
