60KA power lightning arrester product introduction:
OMRDON 60KA secondary surge protection device (SPD) (also known as power lightning arrester, power lightning arrester, surge protector, overvoltage protector) is suitable for lightning electromagnetic pulse (LEMP) protection of TN-S, TN-C-S, TT, IT and other power supply line systems with AC 380V (50Hz/60Hz) and below. It is used at the junction of LPZ OB or LPZ1 zone and LPZ2 zone in lightning strike areas, and its design is in accordance with GB18802.1 and IEC61643-1 technical standards.
60KA power lightning arrester features:
1. Optional remote signaling terminal alarm function, convenient for remote alarm monitoring.
2. It can withstand up to 60KA (8/20 μ s) lightning current surge.
3. Fast response speed, action response time less than 25ns.
4. Flame retardant shell design, easy to install on 35mm electrical rails.
5. The built-in thermal release failure device enables the protector to automatically disconnect when it fails due to overheating or breakdown.
6. The color of the visual alarm window indicates the working status of the protection, green (normal) and red (fault).
Application and installation location of 60KA power lightning arrester product:
OMRDON II series surge protectors are suitable for lightning strike areas at the junction of LPZOB or LPZ1 and LPZ2 zones. They are usually installed in parallel in floor distribution boxes, computer centers, telecommunications rooms, elevator control rooms, frequency conversion equipment control rooms, hospital operating rooms, monitoring rooms, and distribution boxes in places where electronic medical equipment is installed.
