Siemens 3VA2163-5MN36-0BC0 — 63 A SENTRON MCCB for Motor Protection
The Siemens 3VA2163-5MN36-0BC0 is a SENTRON molded case circuit breaker (MCCB) designed specifically for motor protection, rated at 63 A continuous current across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling. Three-pole construction, with an integrated undervoltage release (UVR) and phase failure detection as standard, plus two HQ auxiliary switches for status feedback to the PLC or panel indicators. 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.
Sourcing & Lifecycle
Max power loss is 6.5 W, which keeps panel heat rise manageable in a dense enclosure.
Integration & Mounting
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.
