The 3-pole design switches all three phases simultaneously; neutral is not switched. IP20 finger-safe terminals and pollution degree 3 rating suit it for standard control panels and distribution boards. ## DIN-rail fit and panel integration Installation depth is 55 mm. Energy limitation class 3.","metaTitle":"SENTRON 5SQ2370-2YA06 MCB, 3-pole C 6 A, 400 V AC, 3 kA","metaDescription":"SENTRON 5SQ2370-2YA06 miniature circuit breaker, 3-pole, C-curve, 6 A rated current, 400 V AC, 3 kA breaking capacity per EN 60898.

The only difference is the 6 A rating versus 0.5 A on the 5SQ2370-2YA05. If the circuit load is 6 A or less, it's a direct mechanical and electrical swap — no rewiring needed."},{"question":"What is 5SQ2370-2YA06's number of poles?","answer":"It is a 3-pole device.
