The neutral pole is switched, so you get full isolation on all conductors in a single 3-module-width package. At 63 A, it's sized for a subfeed or a large final circuit, not a branch lighting circuit. Three width units on a DIN rail, 55 mm installation depth. The 3P+N configuration with switched neutral occupies the same footprint as a 4-pole breaker but with the neutral pole switched — common in European distribution boards where the neutral is opened for isolation but not protected.","metaTitle":"Siemens SENTRON 5SQ2670-0KA63 MCB, 4P C-Curve 63 A 3 kA","metaDescription":"Siemens SENTRON 5SQ2670-0KA63 MCB, 4-pole (3P+N), C-curve, 63 A, 3 kA breaking capacity per EN 60898 & IEC 60947-2. 400 V AC, 50 Hz.
