Reliable Type 2 Protection for Electrical Distribution Systems
Type 2 surge protective devices are designed to discharge surge currents produced by indirect lightning strikes and switching operations before damaging transient voltages can reach downstream electrical equipment. Installed in main or sub-distribution boards, they provide an important level of protection for sensitive electronic, control and automation equipment.
The ABB OVR T2 1N 40-275 P TS QS combines high surge-current handling capability with a low residual protection voltage and pluggable construction. Its remote signalling contact allows SPD condition monitoring, while its modular DIN rail format makes it well suited to modern electrical distribution boards and ABB System pro M compact installations.
Typical Applications
- Single-phase 230 V AC electrical distribution boards.
- TT and TN-S low-voltage electrical installations.
- Commercial and industrial distribution systems.
- Building electrical distribution and infrastructure.
- Industrial control panels and automation equipment.
- Protection of electronic controls and sensitive electrical loads.
- Main and sub-distribution boards requiring remote SPD status monitoring.
