Product Description

COMD-250PV DC Circuit Breaker
1. Rated current upto 1250A, operating voltage upto DC1500V;
2. Protection of PV modules from high DC reverse current hazards;
3. Protect PV modules from the hazards of AC feedback currents caused by inverter faults;
4. Each PV string in the state of the load can be safely cut out and isolated;
5. Can be remotely controlled by any one of the photovoltaic system from the system interrupt, even in the negative state can also be completed;
6. The state signal of the DC circuit breaker which is installed in each photovoltaic string can be clearly uploaded;
7. The user can save the installation fee and the copper series, greatly reduce the user cost;
8. Internet preset string connection can be avoided the problem for high temperature of external series inconformity GB14048.1-2006 main circuit terminal and circuit breaker need to reduce capacity more than 30%. It will be more safe and reliable.
