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…). |

Wide range of relays for voltage and current monitoring in 1-phase and 3-phase networks. Simple, 1-module for basic functions, but also a sophisticated version for more accurate measurements in multiple ranges with galvanic separation of power supply from the measured circuit. The offer also includes a relay for protecting the power factor in the range cos ϕ 0.1-0.99 and a relay for monitoring the mains frequency 50/60 Hz in the range 80-120%.
Twilight relays analog, digital and outdoor. External SKS sensor with IP65 protection. Supply voltage AC 230 V or universal in the range AC / DC 12-240V. The relays can also serve as a light switch against solar radiation (shielding, photovoltaics, collectors…).
Level switches monitor the level of conductive liquids in wells, tanks, tanks, etc. They can monitor one to six-level levels with optional refill/drain functions. These are either separately sold products or connected directly in a set with a contactor or motor starter.
