What this MCCB delivers
The Siemens SENTRON 3VA1132-4EF36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection. It carries a continuous current of 32 A at 40 °C ambient, derating to 30 A at 70 °C — the full thermal curve is on the spec table. The interrupting ratings are 121 kA at 240 V AC and 75.6 kA at 415 V AC, which means it can clear high-fault currents on a 400 V distribution bus without upstream coordination issues. The TM240 thermal-magnetic trip unit provides fixed overload and short-circuit protection. No undervoltage release, no ground-fault monitoring, no communication module — this is a straightforward line-protection breaker for standard distribution panels. The front face carries IP40 protection, sufficient for enclosed panel mounting.
Panel fit and dimensions
The 3VA1132-4EF36-0AA0 measures 76.2 mm wide, 130 mm high, and 70 mm deep — a standard 3-pole MCCB footprint for DIN-rail or panel-mount enclosures. The 70 mm depth keeps the breaker within typical 200 mm deep enclosures, leaving room for wiring gutters and busbar connections.
