Why Choose the ABB OVR T2 40-275s P TS QS Surge Protective Device?
The ABB OVR T2 40-275s P TS QS, order code 2CTB815704R0000, is a compact Type 2 surge protective device (SPD) designed to protect low-voltage electrical installations against transient overvoltages caused by indirect lightning effects and switching events. Suitable for installation in main distribution boards, sub-distribution boards and close to sensitive equipment, it combines ABB QuickSafe technology with Safety Reserve functionality for dependable surge protection and preventive maintenance.
Designed for 230/400 V AC systems, the OVR T2 40-275s P TS QS has a maximum continuous operating voltage of 275 V AC, a nominal discharge current In of 20 kA and a maximum discharge current Imax of 40 kA using the 8/20 µs waveform. It also has a 2 kA impulse-current rating using the 10/350 µs waveform and provides a voltage protection level Up of 1.4 kV.
The single-pole SPD features a pluggable cartridge, optical status indication, ABB's patented Safety Reserve system and TS remote signalling through one normally open and one normally closed auxiliary contact. Its compact 17.8 mm DIN-rail width and 100 kA short-circuit withstand capability make it suitable for residential, commercial and industrial distribution applications.

Type 2 Surge Protection with Safety Reserve Monitoring
Type 2 SPDs are designed to discharge transient currents produced by indirect lightning events and switching operations before these overvoltages reach sensitive electrical equipment. The ABB OVR T2 40-275s P TS QS combines a 40 kA maximum 8/20 µs discharge capability with a low 1.4 kV protection level, making it suitable for coordinated protection in main and sub-distribution boards.
The Safety Reserve system distinguishes this 275s model by providing an additional preventive-maintenance function that helps indicate deterioration before complete protection is lost. Together with its visual status indicator, pluggable cartridge and TS auxiliary contacts, this allows maintenance personnel to monitor SPD condition and plan cartridge replacement while reducing the risk of unplanned protection downtime.
Typical Applications
- Main low-voltage distribution switchboards.
- Sub-distribution boards and local electrical panels.
- 230/400 V AC residential installations.
- Commercial buildings and offices.
- Industrial electrical and control panels.
- Protection of sensitive electronic and automation equipment.
- TT, TN-C and TN-S low-voltage distribution networks.
- Installations requiring preventive SPD maintenance indication.
- Systems requiring remote surge-protection status monitoring.
