It breaks up to 187 kA at 240 V, 121 kA at 415 V, and 9 kA at 690 V — so it handles high-fault service entrances and distribution main feeds without cascading upstream. The 500 A rating holds steady through 50 °C; above that it derates to 477 A at 55 °C and 410 A at 70 °C, which matters when the breaker sits in a warm enclosure next to other heat sources. The ETU550 trip unit supports communication, so it can report status and trip events to a BMS or PLC — useful for remote monitoring on a main feeder.","metaTitle":"Siemens SENTRON 3VA2450-5JP32-0AA0 MCCB, 500 A, 187 kA","metaDescription":"Siemens SENTRON 3VA2450-5JP32-0AA0 molded case circuit breaker, 500 A rated at 40 °C, 187 kA breaking at 240 V, 3-pole, ETU550.
