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.","metaTitle":"SENTRON 5SQ2360-0KA40 MCB, 3-pole B-curve 40A 3kA","metaDescription":"SENTRON 5SQ2360-0KA40 3-pole MCB, B-curve 40A, 3kA breaking capacity per EN 60898 & IEC 60947-2, 400V AC, 50 Hz.
