Product code
2721086
Three-Phase Undervoltage control relay 200…240Vac, 2 C/O
Zelio Control - measurement and monitoring relaysCan monitor supply voltage (phases, voltage, current, frequency) to protect motors and other equipment, or physical values such as level, speed, and temperature. Suitable for use in industry and buildings, for simple machine control systems, motor and process control and monitoring, water treatment plant start-up and monitoring, packaging, textile industry, and HVAC.
- Phase monitoring relaysDetect all fault conditions of the supply voltage phases
- Voltage and current monitoring relaysEnsure that equipment receives the correct electrical supply
- Frequency monitoring relaysMonitor fluctuations in voltage frequency
- Level monitoring relaysFill or empty level, suitable for all types of materials
- Pump monitoring relaysMonitor and protect pumps against dry running and overload
- Speed monitoring relaysDetect incorrect process speed
- Temperature monitoring relay for elevator useDesigned for elevator temperature monitoring (EN81)
- Temperature monitoring relaysDesigned for temperature control (heating, cooling, or heating/cooling processes)
