Reliable Surge Protection for AC Electrical Systems
The XH-C40 Series Type 2 AC Surge Protection Device is designed to protect low-voltage electrical installations from transient overvoltage and surge currents caused by indirect lightning strikes, switching operations and other electrical disturbances.
Installed inside distribution boards or control panels, the SPD helps divert surge energy away from connected electrical equipment, reducing the risk of insulation damage, component failure and unexpected downtime.
The XH-C40 Series features a nominal discharge current of 20 kA and a maximum discharge current of 40 kA, making it suitable for residential, commercial and industrial low-voltage AC systems. The device is designed for standard 35 mm DIN rail installation and can be integrated easily into existing electrical distribution equipment.
A visual status indicator allows users to check the operating condition of the surge protection module at a glance. The built-in thermal disconnection function helps isolate the SPD in the event of abnormal overheating or end-of-life conditions.
With a compact modular structure, fast response and simple installation, the XH-C40 Series is suitable for protecting distribution boards, electrical control cabinets, building power systems and other sensitive electrical equipment from transient surge damage.
