Why Choose the IMO B10C3N10A-L Miniature Circuit Breaker?

The IMO B10C3N10A-L is a dependable three-pole plus neutral miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in industrial, commercial and OEM applications. Manufactured by IMO Precision Controls, this breaker provides reliable circuit protection in a compact DIN rail mounted format for control panels, distribution boards and machinery installations.

This model features a 10 A rated current, C curve tripping characteristic and a high 10 kA short-circuit breaking capacity. The C curve response makes it suitable for circuits with moderate inrush currents, including small motors, transformers, control circuits and general inductive loads.

With a 3-pole plus neutral configuration and neutral positioned on the left, the IMO B10C3N10A-L is ideal for three-phase installations requiring switched neutral protection in a compact four-module design. Its standard DIN rail mounting allows fast installation into electrical enclosures and panel boards.

Key Advantages

  • Compact 3-pole plus neutral miniature circuit breaker for three-phase systems.
  • 10 A rated current suitable for control and distribution circuits.
  • C curve tripping characteristic for moderate inrush current applications.
  • 10 kA breaking capacity for dependable fault protection.
  • Neutral positioned on the left for compatible panel layouts.
  • DIN rail mounting for quick installation in control panels and boards.

Key Features

  • IMO Standard 10 kA MCB series.
  • 3-pole plus neutral configuration.
  • Left-hand neutral position.
  • 10 A rated current.
  • C curve trip characteristic.
  • 230/415 V AC rated voltage.
  • 10 kA short-circuit breaking capacity.
  • Four-module DIN rail mounted design.
  • Suitable for industrial and commercial circuit protection.
  • Designed for machinery panels, distribution boards and automation systems.

Reliable Protection for Three-Phase Electrical Systems

Miniature circuit breakers automatically disconnect electrical circuits when an overload or short-circuit fault is detected. This helps protect cables, connected equipment and electrical installations from damage while improving system safety and reliability.

The IMO B10C3N10A-L is particularly suitable for three-phase circuits where neutral switching is required. Its C curve characteristic provides reliable protection for circuits that may experience moderate starting currents, making it a strong choice for panel builders, contractors and OEM machine manufacturers.

Typical Applications

  • Three-phase distribution boards.
  • Industrial control panels.
  • OEM machinery and automation systems.
  • Small motor circuits.
  • Control transformers and inductive loads.
  • Commercial electrical installations.
  • Panel building and machine control systems.
