The Siemens SENTRON 3VA1032-2ED36-0KH0 is a 3-pole molded case circuit breaker (MCCB) rated for 32 A continuous current (Iu) with a TM210 thermal-magnetic overcurrent release. It carries a 52.5 kA interrupting capacity at 240 V, 32 kA at 415 V, and 13.6 kA at 440 V — figures that tell you it handles high-fault industrial feeders, not just branch circuits. The IP40 front protection means it's suited for enclosed panel mounting where dust ingress is controlled.
Ratings and what they mean for fit
The 32 A rating holds flat from 40 °C up to 50 °C, then derates gradually to 28.8 A at 70 °C. That means in a warm panel — say 55 °C ambient — you still get 30.72 A continuous, so no oversizing needed for most industrial enclosures. The interrupting ratings climb with voltage: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. For a 400 V distribution board, the 32 kA figure is the one that governs fault-clearing capability.
Integration and panel fit
The MCCB measures 130 mm high, 76.2 mm wide, and 70 mm deep. That 76.2 mm width is a standard 3-pole MCCB footprint — it fits the same DIN-rail or mounting-plate cutout as other SENTRON 3VA frame sizes. The IP40 front means the operator interface is protected against solid objects over 1 mm, but the body is not sealed against moisture; mount it inside a panel with a gasketed door for washdown areas.
