Siemens 3VA2163-5MN36-0BC0 — 63 A SENTRON MCCB for Motor Protection
Breaking capacity is substantial: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — enough for high-fault utility feeds or transformer secondaries.
Max power loss is 6.5 W, which keeps panel heat rise manageable in a dense enclosure.
Dimensions: 181 mm height, 105 mm width, 86 mm depth — fits standard panel cutouts for 3-pole SENTRON MCCBs. The supplied basic switch is order code 3VA21635MN360AA0. No communication function or ground-fault monitoring on this variant — it is a pure motor-protection breaker with undervoltage release, intended for direct motor feeder protection in a control panel.
