Reliable Type 2 Protection for Low-Voltage Installations
Type 2 surge protective devices are designed to divert surge currents generated by indirect lightning effects and electrical switching events before damaging transient voltages reach downstream equipment. Installed at the origin of an installation, in intermediate distribution boards or close to terminal equipment, they help reduce the risk of insulation damage, electronic component failure and operational disruption.
The ABB OVR T2 1N 40-350 P QS combines a high 40 kA maximum discharge current with pluggable QuickSafe construction for convenient maintenance. Its phase protection cartridge can be replaced with the ABB OVR T2 40-350 C QS, while the neutral protection cartridge is replaceable with the compatible OVR T2 N 80-350 C QS.
Typical Applications
- 230 V AC single-phase electrical distribution boards.
- TT and TN-S low-voltage distribution systems.
- Residential and commercial building installations.
- Industrial control panels and automation systems.
- Intermediate and sub-distribution boards.
- Protection of sensitive electronic and control equipment.
- Electrical installations exposed to switching and indirect lightning transients.
