Why Choose the IMO B10D3025A Miniature Circuit Breaker?

The IMO B10D3025A is a robust 3 pole miniature circuit breaker (MCB) engineered to protect electrical installations against overloads and short circuits in industrial, commercial and OEM applications. Part of the IMO B10 10kA circuit protection range, it combines reliable operation with excellent fault protection for demanding low voltage systems.

Featuring a 25 A rated current, D curve tripping characteristic and a 10 kA short circuit breaking capacity, the B10D3025A is ideal for circuits with high inrush currents such as motors, transformers, compressors and inductive machinery. Its three pole design provides dependable protection for three-phase electrical circuits.

Designed for installation on a standard 35 mm DIN rail, the IMO B10D3025A offers quick installation within distribution boards, switchgear and industrial control panels. Finger safe terminals, clear contact indication and compatibility with pin or fork busbars make it a practical solution for professional electrical installations.
