Why Choose the ABB OVR T2 40-440 P TS QS Surge Protective Device?
The ABB OVR T2 40-440 P TS QS is a compact, single-pole 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 QuickSafe surge protection range, it combines high surge-current capability with pluggable construction, visual status indication and remote signalling.
The OVR T2 40-440 P TS QS has a maximum continuous operating voltage (Uc) of 440 V AC and a nominal discharge current (In) of 20 kA using the standard 8/20 µs waveform. Its maximum discharge current (Imax) is 40 kA, while the voltage protection level (Up) is 1.8 kV, helping limit transient voltage reaching downstream electrical and electronic equipment.
The P configuration provides a replaceable pluggable cartridge, while the TS version incorporates remote signalling for external condition monitoring. ABB's QuickSafe technology is designed to provide rapid and reliable end-of-life disconnection, while the compact 17.8 mm single-module format enables space-efficient installation on DIN rail inside distribution boards and control panels.
