This 110V/120VAC DIN rail protector relay combines over/under current and voltage protection with accurate power consumption metering in a single compact unit. It provides comprehensive electrical system monitoring and protection with adjustable trip points for currents up to 63A, ensuring precise control and preventing equipment damage from power anomalies. Features and Benefits
- Adjustable Over/Under Current & Voltage Protection - Set precise upper and lower limits for both current (40A/63A) and voltage to automatically disconnect loads and safeguard sensitive equipment from harmful power fluctuations.
- Integrated kWh Energy Meter - Monitor real-time and cumulative power consumption directly on the device for accurate energy tracking and cost analysis without needing a separate meter.
- DIN Rail Mounting Design - Enables quick, secure, and organized installation within standard electrical panels, distribution boards, and industrial control cabinets.
- 110V/120VAC Rated Operation - Specifically designed for standard North American residential and commercial single-phase power systems, ensuring compatibility and reliable performance.
- Clear Digital Display - Provides instant, at-a-glance readouts of voltage, current, power, and energy data for straightforward system monitoring and diagnostics. Applications
- Residential Sub-Panel and Appliance Protection - Install to protect high-value home appliances, HVAC systems, or workshop tools from damaging voltage surges, sags, or current overloads.
- Commercial and Light Industrial Control Panels - Integrate into machine control cabinets, small manufacturing equipment, or server racks to ensure operational stability and prevent downtime from electrical faults.
- Renewable Energy System Monitoring - Use in solar or backup power installations to monitor inverter output, protect batteries from over-discharge, and track energy production versus consumption.
- Rental Property and Facility Management - Deploy to monitor tenant power usage, manage energy costs, and provide an added layer of protection for building electrical infrastructure. Note: Professional installation by a qualified electrician is recommended to ensure proper configuration, calibration, and safe operation according to all local electrical codes.
