Protection and monitoring relays - Power voltage - 230 V AC
|
|
Wide range of relays for voltage and current monitoring in 1-phase and 3-phase networks. Also included are relays for power factor monitoring in the range cos ϕ 0.1-0.99 and relays for monitoring the mains frequency 50/60Hz in the range 80-120%. A special category of monitoring relays are twilight relays in analog, digital or increased coverage. The relays can also serve as a light switch against solar radiation (shielding, photovoltaics, collectors…). |
