Breaking capacity is 187 kA at 240 V, 121 kA at 415 V, 55 kA at 440 V, 36 kA at 500 V, and 9 kA at 690 V. At 240 V this MCCB handles high-fault utility feeds; at 690 V the 9 kA figure still covers most industrial motor branch circuits. The 6 kA limited short-time rating (1 s and 0.5 s) supports selective coordination downstream. At 55 °C it carries 477 A, at 60 °C it carries 455 A, at 65 °C it carries 432 A, and at 70 °C it carries 410 A. The 110 mm depth fits standard 400 mm deep enclosures; the 138 mm width and 248 mm height leave room for side-mounted accessories or adjacent breakers on a busbar stack.","metaTitle":"Siemens 3VA2450-5JP32-0AF0 SENTRON MCCB, 500 A, 3-Pole, ETU5","metaDescription":"Siemens SENTRON 3VA2450-5JP32-0AF0 molded case circuit breaker, 500 A rated continuous current at 40 °C, 3-pole, ETU550 electronic trip unit, 187 kA at 240 V.
