Rated for AC/DC circuits, overvoltage category 3, and energy limiting class 3, it provides fast fault clearance to limit let-through energy downstream. ## Panel integration and physical fit Occupies 3 width units on a DIN rail, installation depth 55 mm. IP20 finger-safe terminals. No neutral conductor switching — this is a 3-pole device for 3-phase line protection only. Verify the neutral bar is separate and rated for the application.","metaTitle":"SENTRON 5SQ2360-0KA20 Circuit Breaker, 3-Pole, B, 20 A","metaDescription":"SENTRON 5SQ2360-0KA20 miniature circuit breaker, 3-pole, B-curve, 20 A, 3 kA per EN 60898, 400 V AC, IP20.
