Why Choose the IMO B10D3050A Miniature Circuit Breaker?
The IMO B10D3050A is a high performance 10kA miniature circuit breaker (MCB) designed to provide dependable overload and short circuit protection in demanding industrial, commercial and OEM electrical installations. As part of the robust IMO B10 Series, it offers increased breaking capacity for applications where higher fault levels may be present.
Featuring a D curve tripping characteristic, this miniature circuit breaker is ideal for circuits with high inrush currents, including motors, transformers, solenoids and inductive industrial loads. Its compact DIN rail mounted design, clear contact indication and durable construction make it suitable for control panels, distribution boards and machinery protection.
With a 50A rated current, 3 Pole configuration and a 10kA short circuit breaking capacity, the B10D3050A provides reliable circuit protection for three phase electrical systems requiring high performance and standards-compliant protection.

Reliable Protection for High Inrush Electrical Loads
Miniature circuit breakers automatically disconnect electrical circuits when overload or short circuit faults occur, helping to protect wiring, equipment and connected devices from damage while improving installation safety and reliability.
The D curve characteristic of the IMO B10D3050A allows it to tolerate higher temporary inrush currents than B or C curve devices, making it suitable for inductive loads and equipment that draws a high starting current during normal operation.
Typical Applications
- Industrial control panels.
- Three phase distribution boards.
- Motor circuits and inductive loads.
- Transformer protection circuits.
- OEM machinery and automation systems.
- Commercial and industrial electrical installations.
