The ABB OVR T2 2L 40-440 P TS QS 2CTB803872R5200 is a two-line Type 2 surge protective device (SPD) designed to protect low-voltage electrical distribution systems against transient overvoltages caused by indirect lightning effects and switching events. Part of ABB's OVR QuickSafe range, it combines robust surge-current capability with a compact, pluggable DIN-rail design.
The OVR T2 2L 40-440 P TS QS has a maximum continuous operating voltage Uc of 440 V AC and 560 V DC. It provides a nominal discharge current In of 20 kA and a maximum discharge current Imax of 40 kA using an 8/20 µs waveform, together with a voltage protection level Up of 1.8 kV.
The 2L configuration protects two lines, while ABB's QuickSafe (QS) technology incorporates an integrated thermal disconnector and replaceable protection cartridges. The TS version includes a remote signalling contact for external status monitoring, complementing the device's local end-of-life indication and making it suitable for professional residential, commercial and industrial distribution installations.
Type 2 surge protective devices are designed to discharge currents generated by indirect lightning effects and switching transients on low-voltage power distribution networks. They are commonly installed in main distribution switchboards and sub-distribution boards, where they limit transient voltage before it reaches sensitive downstream electrical and electronic equipment.
The ABB OVR T2 2L 40-440 P TS QS combines 40 kA Imax, 20 kA In and a 1.8 kV Up protection level across two protected lines. QuickSafe technology, replaceable cartridges, local end-of-life indication and TS remote signalling provide a practical combination of surge protection, maintainability and condition monitoring.
