The Siemens SENTRON 3VA1032-4ED32-0AE0 is a 3-pole molded case circuit breaker rated 32 A continuous at 40 °C through 50 °C, with a TM210 thermal-magnetic release designed for line protection. Its interrupting capacity hits 121 kA at 240 V AC and 75.6 kA at 415 V — that means it can safely clear a fault up to those levels without upstream devices needing to trip, which is the core of selective coordination in a distribution panel.
Thermal derating and ambient conditions
Above that it derates gradually: 31 A at 55 °C and 60 °C, then 30 A at 65 °C and 70 °C.
Physical fit and auxiliary options
The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without surprises.
