Why Choose the IMO B4C1N10A Miniature Circuit Breaker?

The IMO B4C1N10A is a compact and dependable 1 pole plus neutral miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in commercial, residential and light industrial installations. As part of the IMO B4 MCB series, it provides practical circuit protection in a space-saving modular format.

This MCB features a C curve tripping characteristic, making it suitable for general electrical circuits with moderate inrush currents. With a 4.5kA short circuit breaking capacity, the B4C1N10A is well suited to distribution boards, control panels and building services applications where reliable low-voltage protection is required.

Rated at 10A and designed for 230/415V AC systems, the IMO B4C1N10A offers simple DIN rail installation and reliable circuit isolation. Its 1P+N configuration provides protection and switching for single-phase circuits requiring neutral disconnection.

Key Advantages

  • Reliable 1 pole plus neutral miniature circuit breaker for circuit protection.
  • 10A rated current suitable for low-voltage electrical installations.
  • C curve tripping characteristic for moderate inrush loads.
  • 4.5kA short circuit breaking capacity.
  • Compact single module DIN rail mounting design.
  • Suitable for distribution boards, panels and building services circuits.

Key Features

  • IMO B4 miniature circuit breaker series.
  • 10A rated current.
  • C curve tripping characteristic.
  • 4.5kA breaking capacity.
