Product Description:
OMRDON surge protector (Surge Protection Device, SPD for short) (also known as power supply lightning protector, power supply lightning arrester, surge protector, overvoltage protector) is designed in accordance with the GB18802.1, IEC61643-1 technical standards; applicable to AC 380V (50Hz/60Hz) and the following TN-S, TN-C-S, TT, IT and other power supply line system of lightning electromagnetic pulse (LEMP) protection, for lightning strike area of the LPZOA zone or LPZOB zone and LPZ1 zone interface.
The product is encapsulated in a flame-retardant shell, built-in high-quality high-speed over-voltage protection devices, the power line induction of lightning high-voltage electromagnetic pulse has a highly efficient protection and defense function.
Functional Features:
- Optional telecommunication terminal alarm function, easy to remote alarm monitoring
- Withstand up to 80KA (8/20μs) lightning current shock.
- Fast reaction speed, action response time is less than 25ns.
- Flame retardant housing designed for easy installation on 35mm electrical rails.
- Built-in thermal release failure disengagement device, so that the protector can be automatically disconnected when it fails due to overheating or breakdown.
- The visual alarm window color indicates the working status of the protection, green (normal), red (fault).
- Reinforced flame-retardant plastic housing
Typical Applications:
- Low-voltage household switchgear
- Floor distribution box
- Main distribution box for machine room
- Outdoor equipment box
- communications base station
- PLC control cabinet

Installation Precautions
1, surge protectors installed in parallel in the line, and remember.
2. Do not connect the line in reverse or wrong.
3, surge protector installed in the front of the protected equipment the closer the better.
4. The equipment needs to be inspected regularly, and the product must be replaced immediately after deterioration.
5. Remember not to work with electricity.
