Moulded Case Circuit Breakers
Heavy-duty protection for main supplies and large loads
Moulded case circuit breakers (MCCBs) handle the currents ordinary MCBs cannot, protecting main incomers, sub-mains and large equipment with adjustable trip settings for precise coordination.
- High current ratings for mains and sub-mains
- Adjustable thermal and magnetic trip settings
- High breaking capacities
- Three and four pole configurations
- Industrial-grade build quality
Applications
Key Features
Main distribution boards, building incomers, generator and inverter changeover panels, motor control centres and industrial switchgear.
How to Choose
Size the frame and trip rating to your supply and cable, and confirm the breaking capacity exceeds the fault level at the installation point. For backup power systems, coordinate MCCB settings with your inverter and generator ratings.
