Omrdon Technology 
OMP-APM60/4, T2 class 60KA (8/20μs) power supply surge protector, secondary power surge protector, used for surge overvoltage protection of sub-distribution cabinets, computer room distribution boxes, cabinets, outdoor equipment boxes
Product Description:
OMRDON (OMRDON) Class II Surge Protector (Surge Protection Device, referred to as SPD) (also known as power supply lightning protector, power supply lightning arrester, surge protector, overvoltage protector) is designed in accordance with GB18802.1, IEC61643-1 technical standards; applies to the AC 380V (50Hz/60Hz) and the following TN-S, TN-C-S, TT, IT and other power supply line system lightning electromagnetic pulse (LEMP) protection, for the lightning strike area LPZ OB or LPZ1, TT, IT and other power supply line system. 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.
The product adopts shielded shell package, built-in high quality high-speed over-voltage protection devices, the power line induction of lightning high-voltage pulse has a highly efficient protection and defense function.
Functional Features::
- Optional telecommunication terminal alarm function, easy to remote alarm monitoring
- Withstand up to 60KA (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

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.
