That full-load rating holds steady across typical panel ambient — you don't lose headroom until the enclosure runs hot. The interrupting ratings tell the real story: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. At 415 V, that 32 kA SCCR covers most industrial distribution panels behind a typical transformer; the 690 V figure matters for mining or marine switchgear where line-to-line voltage is higher. ## Built-in shunt trip and auxiliary contacts The auxiliary contacts share the same form factor as the breaker body, so they don't add panel depth.","metaTitle":"Siemens SENTRON 3VA1050-2ED42-0JC0 MCCB, 50 A, 4-Pole, 52.5","metaDescription":"Siemens SENTRON 3VA1050-2ED42-0JC0 molded case circuit breaker, 50 A rated, 4-pole, 52.5 kA at 240 V.
