Box Type B Power Supply Surge Protective Device (Class II Test)

Product Introduction
DK-380(220)ACm B Type Power Supply series SPD is designed according to IEC standards. It complys with the requirements of GB18802.1-2011 Low-voltage Surge Protective Devices——Part 1: Surge Protective Devices connected to low-voltage power distribution systems——Requirements and tests. This product has air switch outer separating unit, with working indicator lamp, malfunction indicator lamp, lightning strike counter and remote alarm signaling terminal functions. With temperature control circuit breaker and built-in over currents protective circuit, the product can avoid fire danger thoroughly. It can be used for Lightning Protection of L-N-PE(3+1) or (2+1).

Features
a. Adopt international famous brand product for the core components.
b. The box is used according to the maximum discharge current of this SPD, it can be used in extraordinary bad lightning environment.
c. Adopt pressure-sensitive parallel type technology with low residual pressure, large protection capacity.
d. Adopt“3+1”or“1+1”circuit structure, temperature control circuit technology to avoid fire danger, it can be used in different power supply system.
e. Adopt module Lightning Protection components, easy installation and maintenance.
f. With remote alert output and alarm indication and lightning calculating function.
g. Whole machine workmanship observate and study, it can long-term work stably in the severe environment with acid, alkali, salt, fog and moist.
