Why Choose the ABB OVR T2 80-440s P QS Surge Protective Device?
The ABB OVR T2 80-440s P QS, order code 2CTB815708R4100, is a high-performance 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. As part of the ABB OVR QuickSafe surge protection range, this single-pole device combines high surge-current capability with a compact, pluggable DIN-rail design for dependable protection in electrical distribution systems.
The OVR T2 80-440s P QS uses varistor-based surge protection and incorporates an integrated thermal disconnector, end-of-life indication and ABB's QuickSafe safety reserve technology. Its replaceable protection module simplifies servicing, while the mechanical status indicator provides straightforward visual confirmation of the device's operating condition.
With a maximum continuous operating voltage (Uc) of 440 V AC, nominal discharge current (In) of 20 kA and maximum discharge current (Imax) of 80 kA, this Type 2 SPD provides substantial protection against 8/20 µs surge currents. Its 1.8 kV voltage protection level (Up) helps limit transient voltages reaching downstream equipment in 400 V AC electrical systems.
