Why Choose the ABB OVR T2 3L 80-440s P QS Surge Protective Device?
The ABB OVR T2 3L 80-440s P QS, order code 2CTB815708R4700, is a high-performance Type 2 surge protective device (SPD) designed to protect three-phase 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, it combines high surge-current handling capability with pluggable construction for reliable protection and straightforward maintenance.
Designed specifically for TN-C 400 V networks, this three-pole SPD protects all three phase conductors and is suitable for installation in distribution boards and industrial electrical panels. QuickSafe technology provides dependable disconnection at end of life, while individual mechanical status indicators make it easy to check the condition of each protection module during routine inspection.
The OVR T2 3L 80-440s P QS has a maximum continuous operating voltage (Uc) of 440 V AC and can safely discharge surge currents with an 8/20 µs waveform. It provides a maximum discharge current (Imax) of 80 kA, nominal discharge current (In) of 30 kA and voltage protection level (Up) of 2.4 kV, making it a robust solution for surge protection in demanding three-phase distribution systems.
