It's built for line protection duty with an ETU550 electronic trip unit, adjustable N-conductor protection from OFF to 160%, and onboard communication — so this breaker talks to your control system without an extra gateway module. The breaking capacity is the headline number that tells you where this thing can live: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and still 9 kA at 690 V. The 500 A frame is sized for main feeders or large motor branch circuits. At 40 °C ambient you get the full 500 A; at 55 °C it's 477 A, at 65 °C it's 432 A, and at 70 °C it's 410 A — so if your enclosure runs hot, you need to account for that thermal curve in your load calculation. That matters for selective coordination downstream — you can set the delay bands so a branch breaker clears first, keeping this main breaker closed and the rest of the plant live. Physical fit: 110 mm deep, 138 mm wide, 248 mm tall. Line protection MCCB with communication function for status and trip reporting.","metaTitle":"Siemens 3VA2450-6JP32-0AA0 SENTRON MCCB, 500 A, 242 kA at 24","metaDescription":"Siemens 3VA2450-6JP32-0AA0 SENTRON molded case circuit breaker, 500 A rated, 242 kA breaking at 240 V.
