2CTB803873R5200 ABB OVR T2 4L 40-275 P TS QS Type 2 Surge Protective Device

Why Choose the ABB OVR T2 4L 40-275 P TS QS Surge Protective Device?

The ABB OVR T2 4L 40-275 P TS QS, order code 2CTB803873R5200, is a four-pole, pluggable Type 2 surge protective device (SPD) designed to protect low-voltage electrical installations and sensitive equipment against transient overvoltages caused by indirect lightning effects and switching events. Part of the ABB OVR range and ABB's Surge Protection Devices product group, it is designed for 230/400 V AC TN-S networks.

The OVR T2 4L 40-275 P TS QS protects four lines and provides a maximum discharge current (Imax) of 40 kA together with a nominal discharge current (In) of 20 kA using an 8/20 µs surge current waveform. Its 1.25 kV voltage protection level (Up) helps limit transient voltage reaching downstream equipment, while the 275 V AC maximum continuous operating voltage (Uc) suits standard three-phase 230/400 V AC installations.

Featuring replaceable pluggable protection modules, integrated thermal disconnection, mechanical end-of-life indication and NO + NC auxiliary contacts, this SPD supports straightforward servicing and remote status monitoring. Its compact four-module DIN-rail design makes it particularly suitable for commercial and industrial distribution boards requiring dependable Type 2 surge protection with convenient maintenance and signalling.

Four-Line Type 2 Surge Protection with Remote Signalling

Type 2 surge protective devices are used in low-voltage distribution systems to discharge surge currents generated by indirect lightning strikes and to limit induced or conducted transient overvoltages. Their characteristic 8/20 µs waveform makes them suitable for installation in main and sub-distribution boards where coordinated surge protection is required for sensitive downstream electrical and electronic equipment.

The OVR T2 4L 40-275 P TS QS combines four-line protection with a substantial 40 kA maximum discharge capability, replaceable protection modules and integrated remote signalling contacts. This combination makes it particularly suitable for three-phase TN-S installations where compact surge protection, straightforward maintenance and remote condition monitoring are required.

Typical Applications

• 230/400 V AC three-phase TN-S electrical networks.
• Main and sub-distribution boards.
• Industrial electrical distribution systems.
• Commercial building electrical installations.
• Industrial control and automation panels.
• Manufacturing and production facilities.
• Systems requiring remote SPD status monitoring.
• Protection of sensitive electrical and electronic equipment against transient overvoltages.
