Product details

The Siemens SENTRON 3VA1150-5EF32-0AA0 is a 3-pole molded case circuit breaker rated 50 A continuous at 40 °C, with a TM240 thermal-magnetic release that provides fixed thermal and magnetic trip settings for line protection. The thermal derating curve is published: it holds 50 A up to 50 °C, then drops to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C — useful when the breaker lives in a crowded panel with elevated ambient.

The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a 3-pole footprint that fits standard DIN-rail or panel-mount enclosures. Front IP40 protection means it is suited for general-purpose indoor panels where dust ingress is limited.
