Recommended Applications
The Suntree SL7N-63 16A DC circuit breaker may be suitable for:
- Compatible solar PV DC circuits
- DC distribution and protection panels
- Solar combiner and electrical enclosures
- Suitable DC energy-storage installations
- Other DC circuits designed within the breaker’s rated limits
The correct breaker rating depends on the system voltage, expected fault current, conductor size and equipment manufacturer's recommendations.
Installation and Safety
This breaker is intended for DC applications at its specified ratings. Do not assume that a 550V DC rating also makes it suitable for 550V AC applications.
Before installation, verify the circuit's maximum operating voltage, available short-circuit current, wiring configuration and required protective-device rating. Follow the manufacturer's wiring diagram and applicable electrical standards. Installation should be performed by a qualified electrician or solar technician.
A circuit breaker does not replace all other protection devices that a solar installation may require.
