CM-MPS Three-Phase Monitors

Characteristics of CM-MPS three-phase monitors:

• Multifunction device
• 2 c/o (SPDT) contacts
• Powered by the measuring circuit
• Adjustable ON- or OFF-delay (0.1 - 10 s)
• Adjustable threshold values (trip points) for unbalance, over- and undervoltage
• Adjustment of threshold values (trip points) and time delays via direct reading scales
• Setting and operation via front-face operating controls
• LEDs for status indication
• 22.5 mm wide enclosure
• Integrated and snap-on front-face marker
• Sealable transparent cover (accessory)
• Adapter for screw (surface) mounting (accessory)

• Voltage monitoring of mobile three-phase equipment
• Protection of personnel and installations against phase reversal
• Monitoring of the supply voltage to machines and installations
• Protection of equipment against damage caused by unstable supply voltage
• Switching to emergency or auxiliary supply
• Protection of motors against damage caused by unbalanced phase voltages and phase loss
