The SENTRON 5SQ2360-0KA40 is a 3-pole miniature circuit breaker (MCB) rated 40 A with a B tripping characteristic, designed to protect branch circuits in 400 V AC, 50 Hz distribution panels. At 40 A, this is a feeder or sub-main breaker, not a final subcircuit protector.
No neutral switching on this 3P variant, so the neutral bar passes through uninterrupted. Overvoltage category 3 and energy limiting class 3 mean it's designed for fixed-installation mains with reasonable upstream impedance.
Rated 3 kA at 400 V AC per both EN 60898 and IEC 60947-2, so it's certified for the same fault level under either standard.
No — this is a 3-pole device with no neutral conductor switching. The neutral bar is continuous through the breaker.
