Omrdon Technology 
OMP-APM40/4, T2 level 40KA (8/20μs) power supply lightning protector, secondary power supply surge protector, used for surge overvoltage protection of sub-distribution cabinets, computer room distribution boxes, cabinets, outdoor equipment box
Product Description:
OMRDON (OMRDON) II 40KA surge protector (Surge Protection Device, referred to as SPD) (also known as power supply lightning protector, power supply arrester, surge protector, over-voltage protector) its design basis in line with GB18802.1, IEC61643-1 technical standards; for AC 380V (50Hz/60Hz) and below, TN-S, TN-C-S, TT, IT and other power supply line system lightning electromagnetic pulse (LEMP) protection, for the LPZ OB, TN-C-S, TT, IT and other power supply line systems in the area of lightning strikes. (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 LPZ OB or LPZ1 zone and LPZ2 zone junction.
Functional Features::
- Optional telecommunication terminal alarm function, easy to remote alarm monitoring
- Withstand up to 40KA (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).
typical application::
- Floor switchboards
- Machine room distribution box
- PLC cabinet mains power supply
- Network Cabinet Mains
- Outdoor equipment box

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.
