ABB CM-MPN.52P 1SVR760487R8300 3-Phase Monitoring Relay 2CO

The ABB CM-MPN.52P (article 1SVR760487R8300) is a three-phase monitoring relay from ABB's CM range, designed to continuously supervise three-phase supply quality. It operates across a measuring voltage of 3x350-580 V AC at 50/60 Hz and provides a 2 c/o (SPDT) output with contacts rated at 250 V / 4 A.

Technical specifications:

• Series: CM-MPN.52P
• ABB article number: 1SVR760487R8300
• EAN: 4016779852098
• Type: Three-phase monitoring relay
• Measuring voltage: 3x350-580 V AC, 50/60 Hz
• Output contacts: 2 c/o (SPDT), rated 250 V / 4 A
• Contact configuration: selectable 1x2 c/o (common signal) or 2x1 c/o (separate signals for over- and undervoltage)
• Tripping delay: 0, 0.1-30 s (adjustable), selectable ON or OFF delay
• Terminals: push-in (Easy Connect Technology)

Features and benefits:

• Monitors overvoltage, undervoltage, phase unbalance, and phase failure, with individually adjustable threshold values
• Selectable phase sequence monitoring with automatic phase sequence correction
• Flexible output configuration - common signal or separate signals for over- and undervoltage events
• Push-in terminals provide maintenance-free wiring connections
• Optional sealable transparent cover accessory prevents unauthorized setting changes

Applications:

• Protection of three-phase motors against phase loss, unbalance, and voltage faults
• Supply quality monitoring in industrial control panels and switchgear
• Pump and compressor installations requiring phase sequence and voltage supervision
• HVAC and building services equipment requiring three-phase supply integrity checks
