Recommended Applications
The Suntree SL7N-63 32A DC circuit breaker may be suitable for:
- Compatible solar photovoltaic circuits
- Solar DC distribution and protection panels
- Suitable PV combiner-box installations
- Compatible DC energy-storage circuits
- Electrical installations requiring appropriately rated DC overcurrent protection
The correct breaker rating must be determined from the system voltage, expected fault current, cable specifications and equipment manufacturer's requirements.
Installation and Safety
This is a DC circuit breaker, and its 550V DC rating must not be interpreted as a 550V AC rating. Before installation, check the maximum circuit voltage, available short-circuit current, wiring arrangement and required protection characteristics.
Use the manufacturer's wiring diagram and installation instructions. Installation should be carried out by a qualified electrician or solar technician. Ensure the enclosure, conductors and all associated protection devices are appropriately rated for the installation.
