The Siemens SENTRON 3VA1132-6EF36-0AH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a TM240 thermal-magnetic overcurrent release. At 40 °C it holds 32 A continuous, and its interrupting capacity reaches 220 kA at 240 V — enough to clear high-fault industrial feeders without cascading upstream breakers.
Breaking capacity and thermal derating
The 220 kA rating at 240 V drops to 154 kA at 415 V and 121 kA at 440 V, then to 17 kA at 500 V and 690 V — the steep roll-off above 500 V means this MCCB is sized for 240/415 V distribution panels, not 690 V drives. Thermal derating is minimal up to 50 °C (still 32 A), then drops 1 A per 5 °C step to 30 A at 70 °C.
Panel fit and integration
Dimensions are 70 mm deep, 76.2 mm wide, 130 mm high — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling. Rated insulation voltage is 800 V, so it can be used in 690 V line-to-line systems with appropriate clearance. Maximum power loss is 10.6 W, manageable in a sealed enclosure with basic ventilation.
