CM-MPN Multifunctional Three-Phase Control Relays

The CM-MPN.x2 are multifunctional control relays for three-phase power supply. They monitor phase parameters, phase sequence, phase failure, overvoltage and undervoltage, and phase imbalance. The limit values for overvoltage, undervoltage, and phase imbalance are adjustable.

Features

• Three-phase power supply control for phase sequence (can be disconnected), phase failure, overvoltage and undervoltage, and phase imbalance
• Configurable automatic phase sequence correction
• Limit values for phase imbalance, overvoltage, and undervoltage are adjustable as absolute values
• Adjustable or disconnectable trip delay via a logarithmic scale
• Connection with delay or disconnect with delay selectable
• Power supply via the measurement circuit
• Real RMS measurement principle
• 1 x 2 or 2 x 1 c/o (SPDT) configurable contacts
• 3 LEDs for status indication
