Combined Lightning and Surge Protection for Single-Phase Installations
Combined Type 1+2 surge protective devices provide protection against both high-energy lightning currents and transient overvoltages. Type 1 capability enables the SPD to discharge lightning impulse currents characterised by a 10/350 µs waveform, while Type 2 performance limits surge currents characterised by an 8/20 µs waveform, helping protect downstream electrical and electronic equipment.
The ABB OVR T1-T2 QuickSafe range is designed for coordinated protection of low-voltage installations. The OVR T1-T2 1N 12.5-275s P QS combines line-to-neutral and neutral-to-earth protection in a 1+1 arrangement, making it suitable for single-phase installations where coordinated lightning and surge protection is required at the electrical distribution board.
Typical Applications
- Single-phase low-voltage electrical distribution boards.
- 230 V AC electrical installations.
