Why Choose the ABB OVR T1-T2 N 50-440s C QS Replacement Cartridge?
The ABB OVR T1-T2 N 50-440s C QS, order code 2CTB815710R5600, is a pluggable replacement surge protection cartridge for compatible ABB OVR T1-T2 QuickSafe surge protective devices. Designed for the neutral protection path, it forms part of ABB's coordinated Type 1 and Type 2 lightning and surge protection solution for low-voltage electrical distribution systems.
The N designation identifies this cartridge for neutral-path protection within compatible multi-pole OVR T1-T2 assemblies. Its plug-in construction enables the protection element to be replaced independently of the permanently installed SPD base, helping reduce maintenance time and avoiding unnecessary replacement of the complete surge protective device.
With a 50 kA impulse-current rating for the 10/350 µs lightning-current waveform, the OVR T1-T2 N 50-440s C QS is designed to handle high-energy surge currents on the neutral protection path. ABB QuickSafe technology and the replaceable-cartridge architecture provide a practical solution for maintaining coordinated lightning-current and transient-overvoltage protection throughout the service life of compatible installations.

Reliable Neutral-Path Lightning and Surge Protection
In compatible multi-pole surge protection arrangements, the neutral protection element provides a controlled path for high-energy transient currents associated with lightning and other overvoltage events. The ABB OVR T1-T2 N 50-440s C QS is designed for this neutral-path function and provides 50 kA impulse-current capability for the demanding 10/350 µs waveform associated with Type 1 lightning-current testing.
The pluggable cartridge format makes maintenance straightforward. When replacement is required, the cartridge can be exchanged while the compatible wired SPD base remains installed, helping reduce service time and preserve the intended coordinated protection arrangement of the ABB OVR QuickSafe system.
Typical Applications
- Replacement neutral cartridge for compatible ABB OVR T1-T2 QuickSafe SPDs.
- Main low-voltage electrical distribution boards.
- Three-phase plus neutral surge protection assemblies.
- Single-phase plus neutral surge protection assemblies where compatible.
- Industrial control and power distribution panels.
- Commercial and industrial buildings requiring lightning-current protection.
- Preventative maintenance of ABB OVR QuickSafe surge protection systems.
