The Siemens SENTRON 3VA1163-3ED22-0AA0 is a 2-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 63 A at 40 °C through 50 °C with no derating needed. It uses a TM210 thermal-magnetic overcurrent release — the thermal element handles overloads, the magnetic element handles short-circuits — and delivers a 75.6 kA interrupting capacity at 240 V AC. That SCCR figure means it can safely clear faults up to 75.6 kA without welding contacts or rupturing the case, which is the rating that governs coordination with downstream breakers in a distribution panel.
Thermal derating and ambient limits
Current rating holds flat at 63 A from 40 °C to 50 °C, then steps down: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. If the panel ambient runs above 50 °C, the load must be reduced accordingly — the breaker will trip earlier on the thermal curve at elevated temperatures. Operating range spans -25 °C to 70 °C; storage range is -40 °C to 80 °C.
Interrupting ratings and voltage
Rated operating voltage is 415 V AC and 250 V DC. Interrupting capacity at 415 V AC is 52.5 kA, which is the figure to use for 400 V class distribution. Insulation voltage is rated 500 V. IP40 on the front means protection against tools and wires >1 mm — standard for enclosed panel mounting.
Panel fit and dimensions
Width is 50.8 mm (2 in), depth 70 mm (2.76 in), height 130 mm (5.12 in). That 50.8 mm width is a standard 2-pole MCCB footprint — fits most DIN-rail or bolt-on panel layouts without re-drilling. Power loss at rated load is 11.54 W maximum, so account for that in enclosure thermal calculations.
Sourcing and lifecycle
Lifecycle stage is current production. This is a standard catalog item in the SENTRON 3VA family — no last-time-buy or phase-out notice. Sourced and quoted to order through independent distribution; availability and current pricing confirmed at quote time against an RFQ.
