Eaton EMR6-F500-G-1 fasebewakingsrelais 3x200-500V AC 2CO 184789

In industrial control panels, where a phase loss or sequence error can halt a production line, the Eaton EMR6-F500-G-1 monitoring relay continuously checks the three-phase supply. It monitors voltage, phase sequence, and phase failure, and reacts to undervoltage or overvoltage conditions, protecting motors and other equipment from damage.

Key specifications

• Monitored voltage: 3 x 200 - 500 V AC, self-supplied
• Frequency range: 45 - 65 Hz
• Output: 2 changeover contacts (2 CO)
• Rated operational current: 3 A @ 250 V AC (AC-15), 1 A @ 24 V DC (DC-13)
• Adjustable delay times: 0.1 - 30 s for startup and trip
• Reset: automatic or manual, selectable
• Mounting: DIN rail, screw terminals
• Protection: IP50 housing, IP20 terminals
• Operating temperature: -25 to +60 °C

Why choose it

The EMR6-F500-G-1 offers reliable monitoring without an external power supply, simplifying installation. Its adjustable delays and selectable reset mode allow adaptation to specific application needs, reducing nuisance tripping and downtime.

Ideal use cases

• Protecting three-phase motors from phase failure or incorrect rotation
• Monitoring supply quality in industrial machinery and HVAC systems
• Ensuring safe operation of pumps, compressors, and conveyor systems

Good to know

The relay is designed for DIN rail mounting and connects via screw terminals. It operates in ambient temperatures from -25 to +60 °C, making it suitable for a wide range of industrial environments.
