Siemens 3VA1163-5ED32-0AA0 — SENTRON MCCB, 63 A, 3-Pole, TM210
The Siemens 3VA1163-5ED32-0AA0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection, rated 63 A continuous at 40 °C with a 3-pole configuration and a TM210 thermal-magnetic overcurrent release. Its breaking capacity reaches 187 kA at 240 V AC and 121 kA at 415 V, tapering to 17 kA at 500 V and 690 V — the SCCR curve a panel designer needs for selectivity coordination downstream of a transformer or generator.
63 A continuous through the temperature range
The breaker holds its full 63 A rating from 40 °C up through 50 °C, then derates gradually: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. That thermal curve is the one to check when the MCCB shares a crowded enclosure with other heat sources. Maximum power dissipation is 17.3 W — modest enough that ventilation slots in a standard panel cover handle the heat, but worth including in the enclosure thermal budget if the panel is sealed or NEMA-rated.
TM210 release and line-protection design
The TM210 designation means a thermal-magnetic trip unit with a fixed thermal element and a magnetic pickup set at 10x In (630 A). This is a standard line-protection profile — no ground-fault monitoring, no undervoltage release, no communication module on this variant. Rated insulation voltage is 800 V, so the breaker is comfortable in 480/277 V or 600 V panels with headroom to spare. Operating temperature range spans -25 °C to 70 °C; storage from -40 °C to 80 °C.
Panel fit — dimensions and mounting
At 130 mm high, 76.2 mm wide, and 70 mm deep, the 3VA1163-5ED32-0AA0 occupies a 3-pole MCCB footprint that drops into a standard SENTRON 3VA mounting base or panel-mount cutout. No DIN-rail adapter — this is a bolted-frame breaker for distribution panels and switchgear.
