The ABB OVR T2 4L 40-440 P TS QS is a four-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 is designed for three-phase systems requiring protection across four conductors and combines high surge-current capability with pluggable DIN-rail construction.
The OVR T2 4L 40-440 P TS QS provides a maximum discharge current (Imax) of 40 kA and a nominal discharge current (In) of 20 kA using the standard 8/20 µs surge-current waveform. It has a 440 V AC maximum continuous operating voltage (Uc) and a 1.8 kV voltage protection level (Up), providing effective transient overvoltage protection for compatible three-phase power-distribution systems.
Its pluggable QuickSafe construction allows individual protection cartridges to be replaced without changing the complete SPD base. The TS remote signalling function enables external monitoring of device status, while integrated thermal disconnectors and end-of-life indication support straightforward inspection and maintenance. The four-pole configuration is particularly suitable for TNS and compatible IT network applications.
Type 2 surge protective devices are designed to divert surge currents generated by indirect lightning effects and switching operations while limiting the transient overvoltage reaching downstream electrical and electronic equipment. Their ability to discharge currents characterised by an 8/20 µs waveform makes them an important part of coordinated surge protection in low-voltage distribution systems.
The ABB OVR T2 4L 40-440 P TS QS combines 40 kA maximum discharge capability, 20 kA nominal discharge current and a 1.8 kV protection level with four-line QuickSafe construction. Pluggable cartridges, integrated status indication and remote signalling make it particularly practical for industrial and commercial installations where surge protection must be monitored and maintained efficiently.
