SM1 moulded type electric circuit breaker for home solar system is designed to provide overcurrent protection within appliances or electrical equipment, where a branch circuit protection is already provided or not required. Devices are designed for direct current (DC) control circuit applications. SM1-PV specialized in Moulded Case Circuit Breaker dc circuit breaker is widely used in solar power system.

1. Current limiting capacity
Current limiting means the limiting increase of the short circuit current in a circuit,in a circuit protected by the SM1 protect aeries,both the peak value and energy of the short circuit current generated are far less than expected.

2. Double break design
The current-limiting function of the pre-breaking technique is enhanced because of increase in instance arc voltage and a fast drop in the current increase rate.
Reduce the damage and lose of equipment and the power lines caused by a short circuit current,improves the safety,and cuts down on the cost of a secondary protection
