Siemens SENTRON 3VA1132-3EF36-0JH0 — 32 A MCCB, Line Protection, Active Production
The Siemens SENTRON 3VA1132-3EF36-0JH0 is a 3-pole molded case circuit breaker (MCCB) rated 32 A at 40 °C, designed for line protection in distribution panels. Breaking capacity reaches 75.6 kA at 240 VAC, 52.5 kA at 415 VAC, and 32 kA at 440 VAC — sufficient for high-fault industrial mains or sub-distribution boards where the available fault current is known to be elevated. Rated insulation voltage is 800 V, and maximum power loss is 10.6 W. It ships with a shunt trip (STL) release and a 2 auxiliary switch + 1 trip alarm switch HQ configuration, which simplifies integration into safety circuits or remote-trip indication loops — no separate aux block kit to order.
Mounting and Panel Fit
Dimensions are 130 mm high, 76.2 mm wide, and 70 mm deep — fits standard MCCB mounting footprints in Siemens SENTRON distribution boards or third-party enclosures with compatible cutouts. Operating temperature range is -25 °C to +70 °C; storage range -40 °C to +80 °C. Current rating holds flat at 32 A from 40 °C to 50 °C, then derates to 30 A at 70 °C — no derating penalty in typical 40 °C panel ambient.
