3-pole 32 A MCCB with TM240 trip — line protection duty
The TM designation means the trip unit combines a thermal bimetal for overload protection with a magnetic coil for short-circuit response — no electronic adjustment, no communication module, just a fixed-curve breaker for straightforward feeder or distribution protection. At 440 V it still clears 75.6 kA, and at 500 V or 690 V the rating settles to 17 kA — still adequate for most motor branch circuits at those voltages. Thermal derating is published across the full operating range: the breaker carries 32 A flat from 40 °C through 50 °C, then tapers to 31 A at 55–60 °C and 30 A at 65–70 °C (–). That means in a warm panel — say 50 °C ambient — you still get full rated current without a derate factor. The rated insulation voltage (Ui) is 800 V, which covers 480/277 V and 600 V systems with margin, and the maximum operating temperature is 70 °C with storage from -40 °C to 80 °C.
The 3VA1132-5EF36-0KC0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a compact 3-pole footprint that fits standard MCCB mounting rails in distribution panels. It ships with 2 auxiliary switches (HQ type) built in, so you get status feedback without adding external contact blocks. The trip indicator is absent, so visual trip status comes from the handle position alone.
