Why Choose the IMO B10C3N50A-L Miniature Circuit Breaker?

The IMO B10C3N50A-L is a high quality 3 pole and neutral miniature circuit breaker (MCB) designed to protect electrical installations against overloads and short circuits. As part of the industrial grade IMO B10 series, it provides dependable protection for commercial, industrial and OEM applications where reliable three phase circuit protection with neutral switching is required.

Manufactured in accordance with IEC 60898-1, the B10C3N50A-L is built for consistent performance in distribution boards, machinery panels and industrial control systems. Its C curve tripping characteristic makes it suitable for circuits with moderate inrush currents, including lighting, control equipment, small motors and general three phase distribution.

With a 50 A rated current, 3 pole and neutral configuration and 10 kA short circuit breaking capacity, the B10C3N50A-L is ideal for demanding installations requiring compact DIN rail mounted protection and safe isolation of three phase circuits with neutral.

  • Industrial grade 3 pole and neutral miniature circuit breaker.
  • 50 A rated current for three phase circuit protection.
  • C curve tripping characteristic for moderate inrush current loads.
  • 10 kA short circuit breaking capacity for demanding installations.
  • DIN rail mounting for fast installation in panels and distribution boards.
  • Suitable for commercial, industrial and OEM electrical systems.

Key Features

  • IMO B10 miniature circuit breaker series.
  • 3 pole and neutral configuration.
  • 50 A rated current.
  • C curve tripping characteristic.
  • 415 V AC rated voltage.
  • 10 kA breaking capacity.
  • Left-hand neutral configuration.
  • 35 mm DIN rail mounted installation.

Reliable Protection for Three Phase and Neutral Circuits

Miniature circuit breakers automatically disconnect electrical circuits when overload or short circuit conditions occur. This helps protect wiring, connected equipment and personnel while reducing the risk of electrical damage, downtime and unsafe operating conditions.

The IMO B10 range is designed for professional electrical installations requiring higher fault current capability and reliable long term performance. The C curve characteristic provides dependable protection for circuits with moderate inrush current, making the B10C3N50A-L a practical choice for three phase distribution and machinery applications.

Typical Applications

  • Three phase distribution boards.
  • Industrial control panels.
  • Commercial electrical installations.
  • Machinery and OEM equipment.
  • Lighting and general power distribution.
  • Automation and process control systems.
