The interrupting capacity tells the real story: 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. ## Thermal performance and derating That flat curve is unusual; most MCCBs start to derate above 40 °C. It means the 3VA2163-7HM46-0AA0 can be packed into a warm enclosure or mounted near other heat sources without losing capacity. Maximum power dissipation is 4 W, low enough that multiple breakers in a panel do not create a cumulative heat problem. ## Ground-fault monitoring and physical fit This unit includes ground-fault monitoring via summation current formation on the L + N conductors — it measures the vector sum of line and neutral current to detect leakage to earth. That is a built-in residual current detection function, not just a shunt-trip accessory. If you need a shunt trip, UVR, or Modbus communication, that is a different 3VA2 order code.","metaTitle":"Siemens 3VA2163-7HM46-0AA0 SENTRON 63A MCCB, 4-Pole, 330kA a","metaDescription":"Siemens 3VA2163-7HM46-0AA0 SENTRON 63A molded case circuit breaker, 4-pole, line protection. 330 kA at 240 V, flat thermal derating to 70 °C.
