Why Choose the ABB OVR T2 40-550 P TS U Surge Protective Device?
The ABB OVR T2 40-550 P TS U is a compact Type 2 surge protective device (SPD) designed to protect low-voltage electrical installations and sensitive equipment against transient overvoltages caused by indirect lightning events and switching surges. Part of the ABB OVR surge protection range, this single-pole device combines high surge discharge capability with a pluggable cartridge design for convenient installation and maintenance.
Designed for DIN-rail installation in distribution boards and control panels, the OVR T2 40-550 P TS U has a maximum discharge current (Imax) of 40 kA and a nominal discharge current (In) of 10 kA using the standard 8/20 µs surge-current waveform. Its maximum continuous operating voltage is 550 V AC, making it suitable for higher-voltage low-voltage power distribution applications.
The P TS configuration provides a pluggable protection cartridge together with remote signalling capability, helping simplify servicing and allowing surge protection status to be incorporated into monitoring systems. ABB specifies a voltage protection rating of 1.7 kV for this model, while its compact single-module construction occupies approximately 17.8 mm of DIN-rail width.

Reliable Surge Protection for Electrical Installations
Type 2 surge protective devices are used within low-voltage installations to limit transient overvoltages before they can damage connected electrical and electronic equipment. The ABB OVR T2 range is designed to safely divert surge currents with an 8/20 µs waveform while limiting the voltage reaching downstream equipment.
The OVR T2 40-550 P TS U combines a high 40 kA maximum discharge capability with a replaceable pluggable cartridge and remote signalling contact. This makes it particularly practical for distribution boards, industrial control panels and other installations where maintainability and surge-protection status monitoring are important.
Typical Applications
- Low-voltage electrical distribution boards.
- Industrial control and automation panels.
- Commercial electrical installations.
- Protection of sensitive electronic equipment.
- Machinery and industrial power distribution systems.
- Secondary surge protection downstream of the installation supply.
