What This Range Is For
Moulded case circuit breakers for industrial and commercial distribution systems, covering 3P and 4P configurations with frame size 630, rated for AC 50/60Hz, 400V, and insulation voltage up to 1000V, suitable for both domestic and international market applications.
Who Buys This Range
- Electrical wholesalers supplying industrial and commercial distribution equipment
- Panel builders and switchgear assemblers integrating protection into distribution boards
- Solar EPC contractors using MCCBs in hybrid AC/DC systems with 400V AC supply
- OEM/ODM buyers integrating MCCBs into control cabinets and distribution units
Problems It Solves
- Industrial and commercial distribution boards need reliable overcurrent and earth leakage protection with consistent performance across multiple poles
- Existing MCCBs may lack compatibility with both AC 50Hz and 60Hz systems, limiting cross-border use
- Panel builders require a single MCCB series that supports both 3P and 4P configurations without changing mounting or wiring layouts
- Buyers need a circuit breaker with a proven track record in both domestic and international markets, with a clear upgrade path from conventional to smart versions
Where It Is Used
- Main distribution boards in commercial buildings with 3P or 4P power feed
- Industrial control panels requiring overcurrent and earth leakage protection
- Hybrid AC/DC systems in solar or energy storage installations using 400V AC supply
- Switchgear assemblies where consistent pole configuration and mounting are required across multiple units
