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.
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.
