What This Range Is For
Moulded case circuit breakers with integrated earth leakage protection for industrial and commercial distribution boards. The range covers 3P and 4P configurations with a frame size of 630, rated at 400V and 50/60Hz, so a panel builder can source a single breaker type for main and sub-main protection with built-in leakage detection.
Who Buys This Range
- Panel builders assembling industrial and commercial distribution boards
- Switchgear assemblers integrating protection into control cabinets
- Solar EPC contractors needing main protection with leakage detection for DC or AC systems
- OEM buyers integrating a single device for main circuit protection with earth leakage monitoring
Problems It Solves
- Main and sub-main circuits need a breaker with earth leakage protection that matches the frame size and pole count of the existing distribution board
- Separate RCCB and MCCB installations increase panel space and wiring complexity
- Lack of a single device with both moulded case protection and earth leakage detection leads to inconsistent coordination in fault detection
- Buyers need a breaker that can be used in both 3P and 4P configurations without changing the mounting or wiring layout
Where It Is Used
- Main distribution boards in industrial facilities requiring overcurrent and earth leakage protection
- Commercial buildings with 400V power systems needing a single device for 3P or 4P protection
- Control cabinets with high-current circuits where space is limited and protection must be integrated
- Solar installations using 400V AC systems where leakage protection is required at the main switchgear level
Advantages
What Separates This Range
- Integrated earth leakage protection within a moulded case MCCB reduces the need for separate RCCB units
- Available in both 3P and 4P configurations with a frame size of 630 for high-current applications
- Rated at 400V and 50/60Hz, suitable for standard industrial and commercial power systems
- Same factory produces conventional and smart versions, enabling future upgrade paths
- ODM branding available on housing and packaging upon request
