Maximum power loss is 99 W, which factors into the enclosure thermal calculation. ## Integration and Communication The 3VA2450-5JP42-0AA0 includes a communication function, which on the 3VA2 platform typically means it can accept a plug-in communication module for PROFIBUS, PROFINET, or Modbus RTU — enabling remote trip indication, current metering, and parameter adjustment. Dimensions are 184 mm wide, 248 mm high, and 110 mm deep — a standard 4-pole MCCB footprint for the 500 A frame size. No last-time-buy or end-of-life notice applies.","metaTitle":"Siemens 3VA2450-5JP42-0AA0 SENTRON MCCB, 500 A, 4-Pole, ETU5","metaDescription":"Siemens SENTRON 3VA2450-5JP42-0AA0 molded case circuit breaker, 500 A continuous, 4-pole, ETU550 electronic trip unit.
