Macromatic PMP575 | Phase Monitoring Relay, 460-600 VAC, SPDT, 10A/277V, 8-Pin Octal, PMD Series

Description

The Macromatic PMP575 is a high-performance PMD Series phase monitoring relay designed to provide comprehensive protection for three-phase systems operating between 460V and 600V. This universal voltage unit is engineered to safeguard motors and sensitive equipment against five critical fault conditions: phase loss, phase reversal, phase unbalance, undervoltage, and overvoltage. Featuring a standard 8-pin octal plug-in design, the PMP575 is easily socket-mounted for rapid installation or replacement. Its bi-color LED provides immediate visual feedback, glowing green for normal operation and shifting to red to indicate specific fault conditions, making it an essential tool for maintaining uptime in industrial environments.

Key Features

• Universal Voltage Range: One unit covers any 460-600V AC system, reducing the need for multiple inventory variants.
• Adjustable Trip Settings: Fine-tune protection with adjustable undervoltage (80-95% of nominal), phase unbalance (2-10%), and time delay on undervoltage trip and start-up.
• Versatile Compatibility: Designed to work seamlessly with both Wye and Delta three-phase configurations.
• Dual Reset Modes: Offers the choice between automatic or manual reset to fit specific safety and operational protocols.
• Status Diagnostics: A bi-color LED indicates normal operation and simplifies troubleshooting by identifying actual fault conditions.
• Plug-in Convenience: Uses a standard 8-pin octal socket mounting for secure, vibration-resistant placement and easy maintenance.
