Why Choose the ABB OVR T2 N 80-440s P QS Surge Protective Device?
The ABB OVR T2 N 80-440s P QS is a high-performance Type 2 surge protective device (SPD) designed for neutral-to-earth surge protection in low-voltage electrical installations. Identified by ABB order code 2CTB815708R5400, it forms part of the ABB OVR QuickSafe surge protection range and is designed to discharge transient currents generated by indirect lightning strikes and switching overvoltages.
Designed for neutral-to-earth (N-PE) protection, this single-pole SPD combines an 80 kA maximum discharge current with a 30 kA nominal discharge current and ABB QuickSafe technology. Its Safety Reserve design provides enhanced protection availability, while the pluggable construction allows straightforward replacement of the protection cartridge during maintenance.
With a 400 V AC rated voltage, 440 V AC maximum continuous operating voltage and a low 1 kV voltage protection level, the OVR T2 N 80-440s P QS is suitable for neutral-to-earth protection in TT electrical systems. Its compact DIN-rail format makes it well suited to main distribution boards, sub-distribution boards and industrial electrical panels.

Reliable Neutral-to-Earth Surge Protection
Type 2 surge protective devices are designed to discharge transient currents generated by indirect lightning strikes and switching events on low-voltage power distribution networks. The ABB OVR T2 N 80-440s P QS provides dedicated neutral-to-earth protection, helping divert surge energy safely and limit the residual voltage applied to sensitive downstream electrical and electronic equipment.
The device combines high surge-discharge capability with ABB QuickSafe technology, Safety Reserve functionality and a replaceable protection cartridge. Its compact System pro M compatible DIN-rail format enables straightforward installation in main and sub-distribution switchboards, while the visual status indication allows maintenance personnel to quickly assess the condition of the protection device.
