63 A frame, 4-pole, TM210 release — panel fit and breaking capacity
The Siemens SENTRON 3VA1163-3GD46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated at 63 A continuous, with a TM210 thermal-magnetic overcurrent release. At 240 V it interrupts 75.6 kA; at 415 V that drops to 52.5 kA, and at 690 V it still holds 11.9 kA — meaning it handles high-fault utility feeds and large motor branch circuits without cascading upstream. The 63 A rating holds derate-free from 40 °C to 50 °C; at 65 °C it still delivers 60 A, and at 70 °C it's 58 A, so panel ambient is a real factor only above 50 °C.
Integration and mounting
The breaker occupies 101.6 mm width, 130 mm height, and 70 mm depth — a standard 4-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without gland-plate rework. IP40 on the front means it is protected against tools and wires ≥1 mm, but not against water ingress; mount it inside a rated enclosure for washdown or outdoor duty.
Key ratings and what they mean
The TM210 release is a fixed thermal-magnetic design — no interchangeable trip units, so the 63 A frame is the only continuous rating. The 75.6 kA at 240 V is the highest interrupting capacity on the data sheet; at 415 V (common in European industrial panels) it still breaks 52.5 kA, which covers most utility transformer faults up to that voltage. The insulation voltage is rated 800 V, so the breaker can be used in 690 V systems (the 11.9 kA at 690 V confirms that). Power loss is 17.3 W maximum — negligible for panel thermal budgeting but worth noting if the breaker is tightly grouped.
