The Siemens 3VA1463-5EF42-0AC0 is a SENTRON 4-pole molded case circuit breaker rated for 630 A continuous at 40 °C through 50 °C without derating — per the datasheet, it holds full rating across that ambient band. Above 50 °C the current tapers linearly to 583 A at 70 °C, which is the maximum operating temperature. Interrupting capacity reaches 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V and 11.9 kA at 690 V — that spread tells you the part is sized for low-voltage distribution where high fault currents are expected at the service entrance or main switchboard level.
Physical integration and panel fit
Dimensions are 248 mm high, 184 mm wide, 110 mm deep — a standard footprint for a 630 A frame in the SENTRON 3VA platform.
Auxiliary and accessory configuration
The breaker ships with two factory-fitted HQ auxiliary switches (design of the auxiliary switch: 2 auxiliary switches HQ). The supplied basic switch order code is 3VA14635EF420AA0 — useful if you need to order the bare switch separately for a panel build.
