In trackside installations, for DC traction networks, this relay is used to detect the presence of catenary voltage in the cells from the rectifier. The high insulation resistance (up to 12 KV 50hz) offers a high resistance to over-voltages, especially natural phenomena (lightning). In addition, no auxiliary power is required.
TECHNO-ELEC has been providing reliable performance and flexibility in designing custom made relays for over 80 years.
