Why Choose the IMO B10B3N100A Miniature Circuit Breaker?

The IMO B10B3N100A is a high performance 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 IMO B10 circuit protection range, it offers reliable 10 kA fault protection for demanding low voltage distribution systems.

Featuring a B curve tripping characteristic, this MCB is suitable for circuits with relatively low inrush currents where rapid fault disconnection is required. Its 10 kA short circuit breaking capacity helps protect electrical equipment, cabling and switchgear from damage caused by excessive fault current.

With a 100 A current rating and a 3 pole + neutral configuration, the B10B3N100A is ideal for protecting three-phase circuits requiring switched neutral functionality. Its DIN rail mounting format enables fast, secure installation inside distribution boards, switchboards and industrial control panels.

Key Advantages

  • Reliable miniature circuit breaker for industrial and commercial circuit protection.
  • 100 A rated current for higher load three-phase applications.
  • B curve tripping characteristic for rapid response on lower inrush circuits.
  • 10 kA short circuit breaking capacity for enhanced fault protection.
  • 3 pole + neutral configuration for comprehensive circuit isolation.
  • Compact DIN rail mounting for efficient panel installation.

Key Features

  • IMO B10 miniature circuit breaker series.
  • 100 A rated current.
  • B curve protection.
  • 10 kA breaking capacity.
  • 3 pole + neutral construction.
  • Suitable for 415 V AC low voltage systems.
  • VDE approved design for professional installations.
  • DIN rail mounting for switchboards and control panels.

Reliable Protection for Three-Phase Electrical Systems

Miniature circuit breakers such as the IMO B10B3N100A are designed to automatically disconnect a circuit when an overload or short circuit occurs. This helps protect cables, switchgear and connected equipment from damage caused by excessive current.

The B curve characteristic makes this MCB well suited to circuits where fast tripping is required and high inrush current is not expected. Its 3 pole + neutral configuration provides practical protection and isolation for three-phase distribution systems with neutral switching requirements.

Typical Applications

  • Three-phase industrial distribution boards.
  • Commercial electrical installations.
  • Control panels and automation enclosures.
  • Machinery and equipment protection.
  • Power distribution circuits.
  • Panel building, maintenance and electrical installation work.
