Breaking capacity is the headline here: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. The 690 V rating of 52.5 kA still covers most motor-control-center applications. Thermal derating is documented across the ambient range: the breaker holds the full 63 A from 40 °C up to 50 °C, then steps down to 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. It's a 3-pole frame, designed for screw-mounting in a panel or enclosure — not a DIN-rail snap-on. ## Auxiliary contacts and release options Factory-fitted with 2 auxiliary switches (HP type) — these are the status feedback contacts for the panel PLC or indication lamps. The ETU310M electronic trip unit handles the overcurrent protection curves. Maximum power dissipation is 75 W at rated current — account for that heat in the enclosure thermal calculation, especially if the breaker is in a sealed panel with other heat sources.","metaTitle":"Siemens 3VA2163-7MS32-0AB0 SENTRON MCCB, 63 A, 330 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-7MS32-0AB0 molded case circuit breaker, starter protection, 63 A, 330 kA breaking capacity at 240 V.
