surge protector surge protective device
1. Application:
The dehn SPD surge protection device lightning arrester counter is designed in parallel module, flame-retardant shelland nice sealing performance. The product has remote signal interface and fault indicating. It can be installed in the 35mm DIN rail and easy for wire installing. It is produced with the temperature control circuit technology according to IEC standard, it has over current breaker and thermal fuse circuit breaker and can be automatic tripped when it’s deteriorated. We have different specifications in production and we can ensure satisfying for all kinds of demand, easy for maintenance and meet all working voltage levels and lightning discharge current, also we can customize for 220/380V power supply distribution system in lightning protection for various customer requirements.

Adopting Class II SPD to combine “1+1” circuit for protecting low voltage equipment from surge damages. It is applied in TT system and produced according to IEC61643-11/GB18802.11 standard. Our SPD is,
A. Green light indicates normal and red light indicates fault for operation;
B. Built-in circuit breaker and thermal disconnection device, the thermal disconnection device will cut off the SPD from the power line when fault occurs.
C. Impulse counter function records the lightning events.
D. External wiring terminal, easy for wiring and suitable for indoor application.
