Siemens 3VA1463-5EE42-0AA0 — 630 A SENTRON MCCB, 4-Pole, TM220 Release
The Siemens 3VA1463-5EE42-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 630 A at 40 °C ambient — the same rating holds through 50 °C, then derates to 618 A at 55 °C and 583 A at 70 °C, so it holds full rating across most panel interior temperatures without a de-rate penalty. This is a straight electromechanical breaker for standard distribution and feeder protection. Breaking capacity is 187 kA at 240 V AC, 121 kA at 415/440 V, 75.6 kA at 500 V, and 11.9 kA at 690 V — the curve tells you where this breaker can be applied without cascading upstream: at 415 V it handles high-fault industrial panels; at 690 V the 11.9 kA limit means it needs a current-limiting upstream device for high-fault 690 V systems. Power dissipation at full load is 192.9 W — factor that into enclosure ventilation if the panel is sealed or densely populated.
Footprint is 184 mm wide by 248 mm tall by 110 mm deep — a 4-pole frame that fits standard MCCB mounting plates. Front protection is IP40, so it's suited for enclosed panel mounting where the door provides the environmental seal.
