3-Phase Monitoring Relay PWRA440A by CROUZET CONTROLS
The PWRA440A is a high-performance 3-phase monitoring relay designed for precise phase sequence and phase loss detection in electrical systems. Manufactured by CROUZET CONTROLS in Mexico, this relay ensures reliable operation of three-phase power supplies with a robust SPDT 10A relay output.
Product Features:
Monitors phase sequence and detects loss of any phase, even when induced voltage reaches 95% of nominal voltage
LED indicator for relay status
SPDT relay with a maximum load of 10A
Adjustable asymmetry threshold between 5% and 15%
Responsive detection with initial response time of 0.1 seconds at 5% asymmetry and 1 second at 15%
Alarm delay of 100 ms upon phase loss or failure
Suitable for 3 x 220V, 380V, and 440V power supplies
Operates within temperature range from -10°C to +60°C (+14°F to +140°F)
