Why Choose the IMO B10C3N125A-L Miniature Circuit Breaker?

The IMO B10C3N125A-L is a heavy duty miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in industrial, commercial and OEM electrical installations. As part of the trusted IMO B10 circuit protection range, it delivers high performance and a 10 kA breaking capacity for demanding low voltage power distribution systems.

Featuring a C curve tripping characteristic, this MCB is ideal for circuits with moderate inrush currents such as motors, transformers, lighting and general power distribution. Its high fault capacity helps protect electrical equipment, switchgear and wiring while improving system reliability.

With a 125 A current rating and a 3 pole + neutral configuration with the neutral positioned on the left, the B10C3N125A-L is ideally suited to three-phase installations requiring switched neutral protection. Its DIN rail mounting format enables fast installation inside distribution boards, industrial control panels and switchboards.

Key Advantages

  • Reliable miniature circuit breaker for industrial and commercial applications.
  • 125 A rated current for high current three-phase circuits.
  • C curve tripping characteristic for moderate inrush current loads.
  • 10 kA short circuit breaking capacity for dependable fault protection.
  • 3 pole + neutral (left) configuration for comprehensive circuit isolation.
  • Compact DIN rail mounting for straightforward installation.

Key Features

  • IMO B10 miniature circuit breaker series.
  • 125 A rated current.
