Miniature Circuit Breakers

  • Wide range covering common overcurrent, short-circuit, earth leakage and isolation requirements
  • Range of accessories including auxiliary / signal contacts, shunt and undervoltage trips and safety lock offs
  • Custom designs available for non-standard applications
  • Third Party Approval Certifications

Effective Protection and Isolation is at the very heart of good electrical engineering. IMO offers a comprehensive range of modular low-voltage devices to provide protection from Over-Current, Short-Circuit and Earth Leakage faults, alongside power Isolation.
Our MCB range includes standard 10kA and 6kA devices, alongside miniaturised single module 1+N units rated at 4.5kA. The full range of standard trip-curves and current ratings is available, along with the possibility to create customised trip-curve and current options. Offering protection from both Over-Current and Short-Circuit they are ideal for protecting equipment and wiring from high current situations.
