MR – Monitoring relays

The MRM series devices have been developed for the reliable monitoring of AC and DC signals in single-phase and three-phase electrical systems.

• Monitoring of various electrical parameters: voltage, current, power (AC/DC), frequency, phase sequence or power factor cosϕ
• Suitable for use in low-voltage and extra-low-voltage installations thanks to a wide measurement range
• Wide range of monitoring functions: signals when values exceed or fall below the adjustable threshold value or window range
• Power supply: DC 12–48 V or AC 110–240 V
