At 55 °C it derates to 60.48 A, at 60 °C to 59.22 A, at 65 °C to 57.96 A, and at 70 °C to 56.7 A. Maximum power loss is 75 W. That's the heat the breaker dissipates at full rated current — factor it into your enclosure thermal calculation if you're stacking multiple MCCBs in a confined cabinet. ## Motor protection specifics and auxiliary options That gives you two N.O./N.C. signal contacts for status feedback, plus dedicated alarm contacts for trip indication — enough for remote monitoring without an external interface module. Those are the internal subcomponents — useful if you're ordering spare parts for the assembly.","metaTitle":"Siemens 3VA2163-5MN32-0BL0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-5MN32-0BL0 molded case circuit breaker, 63 A rated, 187 kA breaking at 240 V.
