What this MCCB carries — and what it means on the panel
The 3VA1132-5EF36-0DC0: The 32 A rating holds steady from 40 °C up to 50 °C ambient, then derates to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C. If you're packing this into a hot enclosure or a panel near a furnace line, that derating curve is what you need to check against your actual load — the breaker won't trip early, but you can't count on the full 32 A above 50 °C. It ships with an undervoltage release (UVR) built in — that's the '5EF36' designation — and a 2-pole auxiliary switch block (HQ type). The base switch variant is 3VA11325EF360AA0. The UVR means the breaker will trip if control voltage drops below a threshold, which is standard for emergency-off circuits or undervoltage protection on motor feeders. The auxiliary switches give you status feedback to a PLC or annunciator.
Physical fit and panel integration
The 3VA1132-5EF36-0DC0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. That 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint for the SENTRON 3VA frame — it clips onto a DIN rail or mounts with screws to a backplate. The 70 mm depth means it won't stick out past a 100 mm deep enclosure door, so you can fit a standard cover without a bulge. Rated insulation voltage is 800 V, so it's suitable for 480 V and 600 V class systems with margin. Power loss at full load is 13.1 W — that's the heat you need to account for in your enclosure thermal calculation. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C.
