This is a panel-mount component, not a standalone enclosure breaker. ## Panel fit and interchange The 55 mm depth leaves clearance behind most standard enclosure backplates. The 3P+N form factor means it occupies the same footprint as a 4-pole breaker but with the neutral pole switched — verify that your panel's neutral bus bar arrangement expects a switched neutral before dropping this in as a direct replacement for a 4P (all poles protected) unit.","metaTitle":"Siemens SENTRON 5SQ2670-0KA20 MCB, 4-Pole C 20A, 3kA","metaDescription":"Siemens SENTRON 5SQ2670-0KA20 miniature circuit breaker, 4-pole (3P+N), C-curve 20 A, 3 kA breaking capacity per EN 60898, 400 V AC/DC.
