2CTB815708R4100

The ABB OVR T2 80-440s P QS (2CTB815708R4100) is a Type 2 surge protective device designed to protect low-voltage electrical installations and connected equipment against transient voltage surges caused by switching operations and indirect lightning strikes. It is suitable for installation in electrical distribution and sub-distribution boards and is compatible with ABB System pro M compact modular equipment.

The device provides a maximum discharge current of 80 kA (8/20 μs waveform), a nominal discharge current of 30 kA, and a maximum continuous operating voltage of 440 V AC. It incorporates thermal monitoring with Quick Safe technology and a reserve-varistor design, which helps maintain basic surge protection as the primary varistor reaches the end of its service life, until replacement is required. The device has an IP20 protection rating and is intended for installation in a suitable electrical enclosure by a qualified electrician.
