The 2-pole design switches both phase and neutral, giving full isolation on single-phase circuits. It occupies 2 modular width units on a DIN rail, so it fits a standard 18 mm-per-module enclosure. The 76 mm depth and 70 mm installation depth mean it clears most domestic and light commercial distribution boards without a deep-can issue. Rated for overvoltage category III and pollution degree 2, it's suited for fixed installations downstream of the utility meter. The IP20 rating is typical for enclosed distribution boards — no special washdown protection, but fine inside a cabinet. Operating temperature spans -40 °C to 75 °C, so it handles unheated utility rooms or outdoor enclosures in moderate climates.","metaTitle":"Siemens 5SL4220-7 SENTRON MCB, 2-Pole C 20A 400V 10kA","metaDescription":"Siemens 5SL4220-7 SENTRON miniature circuit breaker, 2-pole, C-curve, 20 A, 400 V AC, 10 kA breaking capacity per EN 60898.
