Product details

Line protection breaker, 50 A frame, 4-pole

The Siemens SENTRON 3VA1050-2ED42-0AH0 is a 4-pole molded case circuit breaker (MCCB) designed for line protection, rated 50 A at 40 °C with a TM210 thermal-magnetic release. It carries a breaking capacity of 52.5 kA at 240 V AC, derating to 32 kA at 415 V and 13.6 kA at 440 V — figures that govern its fault-clearing capability in a given installation voltage.

The 50 A rating holds flat from 40 °C through 50 °C ambient, then derates to 49 A at 55 °C and 45 A at 70 °C. Width is 101.6 mm (4 in), depth 70 mm (2.76 in), height 130 mm (5.12 in) — fits a standard 4-pole MCCB footprint on DIN rail or panel-mount base.

Release and auxiliary switch configuration

Maximum power loss is 14.6 W — relevant for thermal budgeting inside a compact panel.
