What is a Surge Protective Device (SPD)?
A Surge Protective Device (SPD) is an essential electrical component designed to protect electrical equipment from damage caused by sudden voltage spikes, known as surges. These surges can result from
• High reliability
With AC Surge Protection Device
With DC circuit breaker, rated voltage AC690V
• Strong adaptability
IP65 design, waterproof, anti dust and anti ultraviolet.
Strict test for high and low temperature, used widely.
The simple installation, the simplified system wiring, the convenient wiring
• Flexible configuration
Used for AC output of 1-50kw inverter. Current rating of the photovoltaic fuse, circuit breaker is modified.
