Integrator note — 5SQ2370-0KA32
The SENTRON 5SQ2370-0KA32 is a 3-pole miniature circuit breaker (MCB) with a C tripping characteristic, rated 32 A at 400 V AC and a breaking capacity of 3 kA per EN 60898. The 3 kA SCCR at 400 V is the standard residential and light-commercial fault level; for higher fault currents you'd step up to an SENTRON 5SL or 5SY series with 6 kA or 10 kA ratings. EN 60898 certifies it for overcurrent protection in household and similar installations — not for industrial motor-starting duty under IEC 60947-2, which the 5SY series covers.
Installation depth is 55 mm — fits standard distribution boards with cover clearance. Overvoltage category 3 (4 kV impulse withstand) suits fixed-installation mains connection. Energy limiting class 3 means it reduces let-through energy under fault, aiding downstream device protection. No neutral switching (3-pole only; neutral bar required separately).
