Caratteristiche:
Class B+C surge protector.
This DIN rail mounted surge protectors are easy to install in any standardized distribution pane or control cabinets.
It is equipped with a thermal disconnection device and provides real-time fault indicators thus allowing complete operational safety.
Green/Red window color showing working status, green=normal, red=abnormal.
Continuous working voltage AC UC 150V/275V/320V.
Installation method 35mm wide electrical installation guide rails.
Shell flame retardant.
Built-in thermal failure trip device, safe to use.
Applicazione:
1. General distribution panel in buildings
2. Distribution box with overhead input in buildings
3. Distribution cabinet and distribution box for outdoor high-power equipment.
Installazione:
The 25kA first level surge protector shall be installed in a waterproof environment and free from violent vibration.
Ensure that the maximum continuous working voltage of the surge protector meets the actual requirements.
The wire connecting the surge protector should be as short and straight as possible, and the total length of the wire should be controlled within 0.5 meters.
Before powering on the power supply, check whether the cable is securely connected to the wiring terminal and whether the ground is reliable.
