Features:
Equipped with a thermal disconnection.
BR-7M 3P is built with a plug-in module and fixed base, which allows an easy and fast maintenance.
DIN rail mounted surge protector is easy to install in any standardized distribution pane or control cabinets.
It is equipped with an internal thermal safety which will disconnect the unit from the AC network in case of the end of life. This disconnection will be indicated by the turn-on of the red mechanical indicator in the front.
Application:
BR-7M AC SPD is suitably used in the TN-C 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.
