Siemens SENTRON 3VA1063-3ED36-0AC0 — 63 A, 3-Pole Molded Case Circuit Breaker
The Siemens SENTRON 3VA1063-3ED36-0AC0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a continuous current of 63 A at 40 °C through 50 °C, derating to 58 A at 70 °C ambient. The TM210 thermal-magnetic release handles overload and short-circuit protection without undervoltage or ground-fault monitoring. Interrupting capacity reaches 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 500 V and 690 V — covering common industrial supply voltages. The 800 V rated insulation voltage suits it for 480 V and 600 V class panels with margin.
Mounting and Panel Fit
At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits standard DIN-rail or panel-mount enclosures. The 3-pole footprint aligns with common SENTRON busbar systems. No auxiliary switch or communication module is fitted — the two HQ auxiliary switches are the only add-on; if your BOM calls for a shunt trip or alarm contact, this base unit omits them.
