Why Choose the ABB OVR T2 N 80-440s C QS Surge Protection Cartridge?
The ABB OVR T2 N 80-440s C QS is a high-performance Type 2 neutral surge protection cartridge designed for use with compatible ABB OVR QuickSafe surge protective devices. As part of the proven ABB OVR QuickSafe surge protection range, it provides N-PE protection against transient overvoltages caused by indirect lightning activity and electrical switching events.
Designed as a replaceable neutral cartridge, the OVR T2 N 80-440s C QS enables the protection element in compatible ABB OVR assemblies to be replaced without changing the complete surge protection device. Its N-PE protection mode makes it suitable for neutral-to-protective-earth surge protection in appropriate low-voltage electrical distribution systems.
With a maximum discharge current (Imax) of 80 kA, nominal discharge current (In) of 30 kA and 440 V AC maximum continuous operating voltage, the OVR T2 N 80-440s C QS provides robust surge protection performance in a compact cartridge format. The cartridge is supplied under ABB order code 2CTB815708R5700.
