What this MCCB is and what the ratings mean for your panel
The SENTRON 3VM1163-3ED22-0AA0 is a 2-pole molded case circuit breaker (MCCB) from the 3VM series, designed for line protection in distribution panels. It carries a TM210 thermal-magnetic trip unit rated at 63 A continuous current, with a fixed thermal element and magnetic instantaneous pickup set at 10× In (630 A). The 63 A rating is sustained up to 50 °C ambient; above that it derates linearly to 58 A at 70 °C, so in a warm enclosure you need to account for the thermal curve rather than the nameplate. Breaking capacity is 76 kA at 240 VAC and 53 kA at 415 VAC — these are the maximum fault currents the breaker can safely interrupt at those voltages without welding contacts or rupturing. For DC systems, the manual (3VA Molded Case Circuit Breaker Manual) provides the specific switching capacity values; the breaker is rated for 250 VDC operation. The 2-pole configuration (50.8 mm wide, 130 mm tall, 70 mm deep) fits standard DIN-rail or panel-mount layouts. Front IP40 protection means it is protected against tools and wires >1 mm, but not against water ingress — keep it inside a rated enclosure.
Integration and wiring considerations
No undervoltage release, no shunt trip, no communication function, no ground-fault monitoring — this is a bare thermal-magnetic breaker for straight line protection. If you need remote tripping or ground-fault indication, you are looking at a different variant in the 3VM family. Maximum power loss is 12 W at rated current. Rated insulation voltage is 500 V. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. The storage range is wider because it governs handling and warehousing, not running load.
