The Siemens 3VA1132-3EF36-0HA0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 32 A at 40 °C — that's the current it handles without tripping in a typical 40 °C panel ambient. The shunt trip release (STL) lets a remote signal or safety circuit force the breaker open, so it fits into emergency-stop chains or undervoltage protection schemes. The thermal-magnetic trip unit is the TM240 — fixed thermal and magnetic settings, no adjustment dial. That keeps the part simple for standard feeder or branch protection where you don't need field-adjustable trip curves. If you need adjustable thermal or magnetic pickup, you'd step up to the electronic trip versions in the 3VA series.
Breaking capacity across voltages — where it fits
Breaking capacity drops as voltage rises: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V and 690 V. At 240 V it's a monster; at 690 V it's a solid distribution breaker.
Current derating — the real continuous rating in a warm panel
The 32 A rating holds steady from 40 °C through 50 °C, then drops to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C.
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint for the 3VA frame size.
