❖Product Specifications
|
The SQUARE D8430 is an industrial-grade three-phase power monitoring relay designed to safeguard electric motors and sensitive downstream machinery against critical power supply faults. It continuously samples incoming voltage waveforms to actively detect conditions such as complete phase loss, phase unbalance, or reversed phase rotation sequence. Upon identifying an electrical anomaly, the unit immediately opens its integrated hard-contact relays to trip the motor starter circuit. |
|
□ Control Output Contact Current Rating: Typically handles 5 A at up to 240 VAC or 600 VAC □ Phase Unbalance Detection Threshold: Hardcoded trigger points calibrated for unbalance deviations > 10% □ Maximum Continuous Power Consumption: Ranges from 5.0 VA up to 7.0 VA □ Transient Spike Protection Immunity: Capable of arresting voltage spikes up to 5000 V □ Ambient Operating Temperature Range: [-5 °C, 50 °C] □ Storage Temperature Envelope: [-20 °C, 70 °C] |
❖Product Application
(1) Industrial Motor System Protection: Safely monitors three-phase power lines supplying critical water pumps, compressors, and heavy conveyor belt systems.
(2) HVAC Chiller and Fan Grid Monitoring: Safeguards large commercial cooling fans and refrigeration compressors against overheating caused by single-phasing faults.
(3) Material Handling and Lift Machinery: Prevents reverse-rotation hazards in elevators, hoists, and automated cranes by immediately tripping on phase reversal faults.
