The Siemens SENTRON 3VA1132-3GE42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated at 32 A continuous, designed for line protection in distribution panels. It carries a TM220 thermal-magnetic overcurrent release — fixed thermal and magnetic trip settings, no electronic adjustment — so it's a straight swap-in for a standard feeder or branch circuit where you need coordinated protection without commissioning software.
Breaking capacity across voltages
Breaking capacity is specified at five voltage points: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That 75.6 kA at 240 V gives you headroom on high-fault 277/480 V wye secondary panels where the line-to-neutral fault can exceed 50 kA. The drop to 11.9 kA at 500 V and 690 V is typical for a 32 A frame — verify coordination if your system impedance is low at those voltages.
Thermal derating and panel fit
Current rating holds at 32 A from 40 °C up to 50 °C, then derates to 31 A at 55–60 °C and 30 A at 65–70 °C. That means in a warm enclosure — say a non-ventilated panel near a conveyor drive — you still get full 32 A up to 50 °C, which covers most industrial environments without upsizing. Dimensions are 130 mm high, 101.6 mm wide, 70 mm deep; the 70 mm depth is shallow enough to fit a 200 mm deep enclosure with room for wiring gutters. Front IP40 keeps dust out of the toggle and rating plug area.
