At 240 V it interrupts 330 kA; at 415 V and 440 V it holds 242 kA; at 500 V it drops to 187 kA; at 690 V it is rated 3.7 kA. The steep drop at 690 V (3.7 kA) tells you this is not a 690 V main breaker; it belongs on a 400–500 V distribution bus. ## Motor protection logic and communication This MCCB has a communication function and an other measurement function via the SENTRON communication module. No undervoltage release is fitted. That is unusual for a molded case breaker; most have to be downsized above 40 °C. Power loss is 4 W maximum, which is low enough that ventilation around the breaker is not critical in a typical enclosure. ## Physical fit and storage","metaTitle":"Siemens 3VA2163-7MQ32-0AA0 SENTRON MCCB, 63 A, 3-Pole, Motor","metaDescription":"Siemens SENTRON 3VA2163-7MQ32-0AA0 molded case circuit breaker, 63 A rated, 3-pole, motor protection design with communication function.
