The LXPRC-4W from Broyce Control is a compact and reliable three-phase voltage monitoring relay designed for industrial applications. Here's a detailed look at what it offers:

Key Features

• Monitoring Function:
  • Under-voltage and over-voltage detection (window type)
• Supply Voltage:
  • Monitors its own three-phase, 4-wire supply at 230V AC
• Trip Levels:
  • Adjustable:
    • Under-voltage: 75–95% of nominal
    • Over-voltage: 105–125% of nominal
• Hysteresis:
  • Approximately 2% to prevent relay chatter
• Time Delay:
  • Adjustable from 0.2 to 10 seconds for stable operation
• Output Relay:
  • SPDT, rated at 8A  250V AC1
• Mounting:
  • Slim 17.5mm DIN rail housing
• Phase & Neutral Detection:
  • Relay energizes only when all phases and neutral are present and within limits
• Phase Sequence Independence:
  • Operates regardless of phase rotation
