Eaton DIN Rail Phase and Voltage Monitoring Relay, 50 to 60Hz Frequency Sensing Range - EMR6 Series - 184779 EMR6-W500-D-1
Use this phase and voltage monitoring relay from Eaton to protect switchgear while monitoring a 3-phase power supply. It's suitable for a wide range of applications, from process control engineering to monitoring equipment. The frequency sensing range of 50 to 60Hz makes it compatible with European and US mains supplies. It's highly resistant to shock and weather, immune to radiation and has an operating temperature range of -25°C to +60°C, meaning you can use it in harsh industrial environments.
Features & Benefits

• Overcurrent and surge protection reduces the risk of damage to components
Why do I need to monitor a 3-phase power supply?
Monitoring a 3-phase power supply is essential, as power fluctuations can cause serious damage to devices. It's more costly to repair or replace 3-phase transformers than single-phase alternatives, so it's important to protect them.
