Why Choose the ABB OVR T2-T3 N 80-440 C QS Surge Protection Device?
The ABB OVR T2-T3 N 80-440 C QS, order code 2CTB803886R0100, is a high-performance Type 2+3 surge protection device (SPD) cartridge designed to protect low-voltage electrical installations and sensitive equipment against transient overvoltages caused by indirect lightning events and electrical switching surges. As part of the ABB OVR QuickSafe surge protection range, it is designed for use in intermediate distribution boards and close to terminal equipment requiring effective surge protection.
This single-pole neutral protection cartridge combines a maximum discharge current (Imax) of 80 kA with a nominal discharge current (In) of 30 kA and an impulse current (Iimp) of 6.25 kA. Its Type 2+3 classification makes it suitable for coordinated protection against surge currents while providing a low residual voltage level for sensitive downstream electrical and electronic equipment.
With a 400 V AC nominal voltage, 440 V AC maximum continuous operating voltage and 1.4 kV voltage protection level (Up), the OVR T2-T3 N 80-440 C QS is suited to TT and TN-S low-voltage distribution systems. Its compact replaceable-cartridge construction enables straightforward servicing within compatible ABB OVR surge protection assemblies.
