Interrupting capacity hits 187 kA at 240 V AC and still holds 121 kA at 415 V and 440 V, so it clears high-fault bolted faults without cascading upstream. At 690 V the rating drops to 3.7 kA — that's the limit for 690 V line-side applications; keep it on the 400 V bus for the full interrupting muscle. ## Line protection with a communication window This MCCB is designed for line protection — feeder and distribution circuits, not motor branch. It carries a communication function, so it can talk to a higher-level energy management or SCADA system via the SENTRON communication modules. No undervoltage release fitted, and no voltage trigger; trip indication is present, so you get a local flag when it's tripped. Initial setting is 16 A, adjustable up to the full-scale 63 A — the thermal-magnetic or electronic trip unit allows that range.","metaTitle":"Siemens 3VA2163-5JQ32-0AF0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2163-5JQ32-0AF0 molded case circuit breaker, 63 A rated, 3-pole, 187 kA interrupting at 240 V.
