The surge protector is mainly used in surge protection for lightning or other transient over-voltage from low voltage power
distribution system and electrical equipment.
Product is built-in overheating and over-current protection function, which can provide low voltage power
distribution system and electric equipment with class C (Ⅱ level classification test) lightning protection. This type
adopts to 35 mm DIN TTW Guide installation. The surge protection module can be changed independently, which
possesses ease of installation and maintenance. With a remote communication alarm interface (dry contact), it is
convenient to monitor the status of the SPD.
