The Siemens SENTRON 3VA1032-2ED36-0AD0 is a 3-pole molded case circuit breaker (MCCB) rated for 32 A at 40 °C, with a TM210 thermal-magnetic release designed for line protection — meaning it handles overloads and short circuits in distribution panels, motor control centers, or as a main feeder breaker. The 52.5 kA breaking capacity at 240 V gives you headroom on high-fault utility feeds, and it still interrupts 32 kA at 415 V and 13.6 kA at 440 V, so it holds up on 480 V delta systems common in North American plants.
This MCCB's interrupting rating drops as system voltage rises: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. The three-pole construction switches all phases simultaneously, so it's suitable for three-phase feeders and motor branch circuits.
Sizing and thermal performance across temperature
The breaker holds its full 32 A rating from 40 °C through 50 °C, then derates to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C.
The 3VA1032-2ED36-0AD0 measures 130 mm tall, 76.2 mm wide, and 70 mm deep. Width of 76.2 mm (3 inches) is standard for a 3-pole 32 A MCCB — it occupies three 25 mm DIN spaces if mounted on a rail, or bolts directly to a backplate. No undervoltage release or shunt trip is built in (the listing shows no voltage trigger and no undervoltage release), so if you need remote trip, you'll add an external accessory.
