SENTRON 3VA1063-2ED42-0HH0 — 63 A MCCB for Line Protection
The Siemens 3VA1063-2ED42-0HH0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection in distribution panels. It carries a continuous current rating of 63 A at 40 °C, with no derating needed up to 50 °C — still 63 A at 50 °C — and only a slight drop to 58 A at 70 °C. The 4-pole configuration suits three-phase systems with a switched neutral. Breaking capacity is rated at 52.5 kA at 240 V, 32 kA at 415 V, and 7.5 kA at 690 V — covering most industrial fault-current scenarios up to the 690 V tier. The rated insulation voltage is 800 V, giving headroom for 690 V systems. This variant ships with a shunt trip (STL) for remote tripping and two auxiliary switches plus one trip alarm switch (HQ configuration), allowing status feedback to a PLC or annunciator panel. No undervoltage release or ground-fault monitoring is fitted on this order code.
Panel Fit and Mounting
Dimensions are 130 mm height, 101.6 mm width, and 70 mm depth — a standard SENTRON 3VA footprint that fits existing Siemens panel cutouts and busbar systems. The 4-pole width matches the 101.6 mm (4-inch) frame, so a panel designed for a 3VA1010 or 3VA1110 in the same pole count will accept this unit without re-drilling.
