Why Choose the ABB OVR T2 40-275 Surge Protective Device?
The ABB OVR T2 40-275, ABB order code 2CTB804201R1100, is a compact Type 2 surge protective device (SPD) designed to protect low-voltage electrical installations against transient overvoltages caused by indirect lightning effects and electrical switching events. This order code identifies the OVR T2 40-275 (x20) packaged version, supplied in a pack quantity of 20 devices.
As part of the ABB OVR Type 2 surge protection range, the OVR T2 40-275 uses metal-oxide varistor technology to divert damaging surge currents away from downstream electrical and electronic equipment. Its fixed, non-pluggable monobloc construction provides a straightforward surge protection solution for DIN rail installation in distribution boards and control panels.
The device has a 230 V AC nominal voltage and a 275 V AC maximum continuous operating voltage (Uc). It provides a 20 kA nominal discharge current (In) and a 40 kA maximum discharge current (Imax) using an 8/20 µs waveform, together with a 1.4 kV voltage protection level (Up).
Key Advantages
