Features:
This spd is module design, nice sealing performance, matched remote signal interface and faulty indicator window, installed in 35mm DIN rail, easy to wire.
There has temperature control technology, over current fuse and thermal circuit breaker, automatic trip when degraded.
Different specification satisfy, easy to maintain, could supply different working voltage level and lightning discharge current, also could customized according to different requirement.
Large flow capacity, low residual voltage, fast response speed, when the automatic tripping degradation, visual instructions to monitor the window into a red.
Application:
BR-7M AC SPD is suitably used in the TN-S power supply system of AC 50/60HZ.
Suitable for system power protection, such as power distribution cabinet, switch cabinet, switch cabinet, AC distribution board, etc.
SPD to protect from direct and indirect lightning impulse and other transient over voltage.
Installation:
The protector is installed with standard 35mm track.
The protector is connected by 4 ~ 35mm copper wire.
No need to adjust after the protector is installed as required.
During operation, regularly check whether the module is red; replace the failed component in time.
