It is designed specifically for motor protection, with phase failure detection and undervoltage release absent (no UVR coil to wire), so it relies on the electronic trip unit for coordinated protection. Interrupting capacity is 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 15.3 kA at 690 V — per the datasheet, these are the maximum fault currents the breaker can safely clear at each voltage level. For a 480 V panel, the 242 kA rating at 440 V is the closest published figure; selectivity coordination studies should use the 500 V value (187 kA) as a conservative bound if the system voltage falls between published points. The electronic trip unit includes a communication function and other measurement functions, plus a trip indicator and voltage trigger. The 110 mm depth is the body depth, not including handle projection; verify clearance to the enclosure door. Three-pole configuration with no undervoltage release means the breaker trips only on overcurrent or via the communication interface — no separate control power required for the trip mechanism. The voltage trigger input allows remote shunt-trip capability if wired externally.","metaTitle":"Siemens 3VA2450-7MQ32-0JH0 SENTRON MCCB, 500 A, 3-Pole, Moto","metaDescription":"Siemens SENTRON 3VA2450-7MQ32-0JH0 molded case circuit breaker, 500 A rated, 3-pole, motor protection design with communication.
