Snaps onto standard 35 mm DIN rail, occupies 2 width units (about 36 mm), and has a 55 mm installation depth — no surprises for a panel already laid out for SENTRON 5SQ-series breakers. IP20 finger-safe terminals are standard for enclosed distribution boards. The 1P+N design means you get neutral switching in a 2-module width, which is tighter than a 4-pole unit for single-phase final subcircuits.","metaTitle":"SENTRON 5SQ2570-0KA50 MCB, 2-Pole C-Curve 50A, 3kA","metaDescription":"SENTRON 5SQ2570-0KA50 miniature circuit breaker, 2-pole 1P+N, C-curve 50A, 3kA breaking capacity per EN 60898 at 240V AC.
