Why Choose the ABB OVR T2 40-350 C QS Surge Protection Cartridge?
The ABB OVR T2 40-350 C QS is a replaceable Type 2 surge protection cartridge designed for use with compatible ABB OVR surge protective devices. Identified by ABB order code 2CTB803886R1000, this cartridge provides dependable protection against transient overvoltages caused by indirect lightning effects and switching events in low-voltage electrical installations.
As part of the ABB OVR Type 2 QuickSafe surge protection range, the OVR T2 40-350 C QS uses a pluggable cartridge format that simplifies maintenance and replacement without requiring the complete surge protective device assembly to be changed. It is designed for phase protection in compatible OVR configurations and incorporates ABB QuickSafe technology for reliable surge protection performance.
The cartridge has a maximum continuous operating voltage (Uc) of 350 V AC, a nominal discharge current (In) of 20 kA and a maximum discharge current (Imax) of 40 kA using an 8/20 µs current waveform. These characteristics make it suitable for protecting electrical distribution equipment and sensitive downstream loads against transient surge events.

Reliable Protection Against Transient Overvoltages
Type 2 surge protective devices are used within low-voltage distribution systems to limit transient overvoltages caused by indirect lightning effects and electrical switching operations. By diverting surge current away from downstream equipment, they help reduce the risk of insulation damage, premature component failure and disruption to sensitive electrical and electronic systems.
The ABB OVR T2 40-350 C QS provides the replaceable phase protection element used in compatible OVR Type 2 assemblies. Its pluggable design allows a worn or end-of-life cartridge to be replaced without changing the complete SPD base, helping simplify maintenance and restore surge protection quickly.
Typical Applications
- Replacement cartridge for compatible ABB OVR Type 2 surge protective devices.
- Low-voltage electrical distribution boards.
- Industrial control panels and automation systems.
- Commercial and industrial electrical installations.
- Protection of sensitive electronic and control equipment.
- Building electrical distribution and infrastructure systems.
