Why Choose the IMO B10C3N40A-L Miniature Circuit Breaker?
The IMO B10C3N40A-L is a robust miniature circuit breaker (MCB) designed to provide reliable protection against overloads and short circuits in commercial, industrial and OEM electrical installations. As part of the high performance IMO B10 miniature circuit breaker range, it offers a higher short circuit breaking capacity than standard 6 kA devices, making it suitable for demanding panel and distribution applications.
Manufactured for professional electrical systems, the B10C3N40A-L combines compact DIN rail mounting with dependable switching performance and clear circuit protection functionality. Its modular design makes it suitable for control panels, distribution boards and machinery systems where reliable three-phase protection is required.
With a 40 A rated current, C curve tripping characteristic, 3 pole plus neutral configuration, left-hand neutral position and a 10 kA short circuit breaking capacity, the IMO B10C3N40A-L is ideal for three-phase circuits supplying general industrial loads, control equipment and commercial power distribution systems.
Key Advantages
- High capacity miniature circuit breaker for three-phase electrical protection.
- 40 A rated current for industrial and commercial installations.
- C curve tripping characteristic suitable for general-purpose loads with moderate inrush current.
- 3 pole plus neutral configuration with neutral positioned on the left.
- 10 kA breaking capacity for enhanced short circuit protection.
- DIN rail mounting for fast installation in panels and distribution boards.
Key Features
- IMO B10 miniature circuit breaker series.
- 40 A rated current.
- C curve tripping characteristic.
- 3 pole plus neutral configuration.
- Neutral on left layout.
- 10 kA short circuit breaking capacity.
- 230/415 V AC rated operation.
- 35 mm DIN rail mounting.
Reliable Protection for Three-Phase Electrical Systems
The IMO B10C3N40A-L automatically disconnects the circuit when overload or short circuit conditions occur, helping protect cabling, distribution equipment and connected loads from electrical damage. Its C curve characteristic provides reliable protection for circuits where moderate inrush current is expected during normal operation.
The 3 pole plus neutral arrangement allows three-phase conductors and the neutral conductor to be switched together, while the left-hand neutral layout supports panel configurations that require neutral positioning before the phase poles. This makes the B10C3N40A-L a practical choice for panel builders, electrical contractors and industrial maintenance teams.
Typical Applications
- Three-phase distribution boards.
- Industrial control panels.
- Commercial electrical installations.
- Machinery and OEM equipment.
- General power distribution circuits.
- Panel building and automation systems.
