Product details

The Siemens 3VA1125-5EF36-0AF0 is a SENTRON molded case circuit breaker (MCCB) rated for 25 A continuous at 40 °C with a TM240 thermal-magnetic release — that fixed trip unit means the breaker is sized for a specific load and not field-adjustable, so confirm your continuous load is at or under 25 A before committing the BOM line. Three-pole construction, so it switches all phases in a three-phase circuit. The breaker carries a built-in auxiliary switch and trip alarm switch (1 each, HQ design), which gives you remote status indication without adding a separate accessory module. That saves a DIN slot and a wiring step.

The 3VA1125-5EF36-0AF0 measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard MCCB footprint that drops into SENTRON mounting bases or DIN-rail adapters without panel rework.

Frequently asked questions

Will 3VA1125-5EF36-0AF0 drop into a panel specified around 3VA1110-5ED36-0AC0?

Both are 3-pole SENTRON MCCBs sharing the same 70 mm depth and 76.2 mm width footprint, so the mechanical fit is identical. The difference is the trip rating — the 3VA1110-5ED36-0AC0 uses a different release curve. Verify the load current matches the 25 A rating before swapping.
