This is a starter-protection variant — designed to sit ahead of a motor starter or contactor in a panel, providing short-circuit and overload protection under a single device footprint. The interrupting ratings drop with voltage: 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. ## Thermal derating and endurance The 63 A rating holds flat through 50 °C; above that it derates linearly to 56.7 A at 70 °C. Power loss at rated load hits 75 W max — that heat has to leave the enclosure. ## Auxiliary and trip configuration The auxiliary contact block is a 2+1+1 configuration: two auxiliary switches (NO/NC), one trip alarm switch (signals that the breaker tripped on fault), and one electrical alarm switch (signals the breaker is off). The shunt trip (STL) allows remote tripping from a PLC or E-stop circuit. The integrated auxiliary trip module carries order code 3VA9688-0BL33. The basic switch assembly is 3VA2163-7MS36-0AA0. No rewiring needed if replacing a similarly dimensioned 3VA2 unit; check the lug spacing for busbar alignment. ## What it does not include This variant has no communication function (no Modbus, PROFIBUS, or IO-Link), no phase-failure detection, no ground-fault monitoring, and no undervoltage release. If remote monitoring or ground-fault protection is needed, look at the 3VA2 with the communication module or a separate ground-fault relay. The ETU310M trip unit handles overload and short-circuit only — it does not perform power metering or energy logging.","metaTitle":"Siemens 3VA2163-7MS36-0KL0 MCCB, 63 A, 3-pole, 330 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-7MS36-0KL0 molded case circuit breaker, 63 A, 3-pole, 330 kA interrupting at 240 V.
