Functional characteristics
♦ The protection grade of the AC junction box reaches IP65, and the wall-mounted sealed cabinet that can meet the requirements of outdoor installation:
♦ Satisfy the simultaneous access to multiple-channel group-type inverters, each incoming line is protected by a thermal magnetic circuit breaker, and the rated voltage reaches AC690V:
♦ The use of a special high-voltage lightning protector can meet the overvoltage and lightning protection between three phases , The working voltage reaches above AC480V:
♦ The busbars in the box are all connected by electroplated or purified busbars to reduce the internal resistance and connection points of the busbars;
♦ The transmission line uses circuit breakers, load disconnectors or fuses.
