This is a current-production spare for any 630 A SENTRON install. The 184 mm width for a 4-pole unit means it occupies roughly the same panel space as two 2-pole breakers side by side. No communication module or undervoltage release is fitted (no voltage trigger, no undervoltage release), so it is a straightforward thermal-magnetic breaker with no auxiliary electronics to fail.","metaTitle":"Siemens 3VA1463-5FF42-0AA0 SENTRON MCCB, 630 A, 4-Pole, TM24","metaDescription":"Siemens 3VA1463-5FF42-0AA0 SENTRON molded case circuit breaker, 630 A continuous, 4-pole, TM240 release.
