It is designed for line protection, not feeder or motor protection, so the trip curve is fixed for cable and busbar fault isolation. The interrupting ratings climb to 187 kA at 240 V and 121 kA at 415/440 V, dropping to 75.6 kA at 500 V and 3 kA at 690 V. The basic switch variant is 3VA20635JQ320AA0. Maximum power loss is 5.4 W, manageable for enclosure heat budgets. The 3-pole form factor matches standard SENTRON mounting bases; no adapter plate needed for most Siemens switchboards.","metaTitle":"Siemens 3VA2063-5JQ32-0JA0 SENTRON MCCB, 63 A, 3-pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5JQ32-0JA0 molded case circuit breaker. 63 A continuous, 3-pole, line protection with shunt trip.
