The Siemens 3VA1063-3ED36-0DA0 is a SENTRON molded case circuit breaker (MCCB) rated for 63 A continuous current (Iu) at 40 °C, with a 3-pole configuration and a TM210 thermal-magnetic overcurrent release. This is a line-protection device — not a motor-protective breaker — so it is sized for feeder or distribution circuits where the load is resistive or a mix, not for direct motor starting duty. The interrupting ratings are 75.6 kA at 240 V and 52.5 kA at 415 V, which gives substantial fault-clearing headroom on a 400 V panelboard; at 690 V it drops to 7.5 kA, so verify the available fault current if this lands on a 690 V bus.
Above that it begins to taper: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C.
The 3VA1063-3ED36-0DA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. It is designed for DIN-rail mounting in a standard distribution panel. The width of 76.2 mm (3-module wide) fits a typical 3-pole MCCB footprint. No auxiliary contact version is included, so if remote status indication is needed, an auxiliary contact block must be added separately.
