Timing Counting Function Voltage Relay Phase Sequence Protection

Timing Counting Function Voltage Relay Phase Sequence Protection. True RMS Voltage Measurement: Built-in microprocessors ensure voltage measurement accuracy is within 1%. Multi-Function Protection: Protects against over-voltage, under-voltage, phase failure, sequence, and unbalance. LCD Display & Button Setting: Features LCD for fault info and button settings to check values and toggle protection. Wide Voltage Range: Rated supply voltage supports AC220V~450V for 3-Phase 3-Wire systems. DIN Rail Mounting: Miniature size designed for standard 35mm width DIN rail installation. Fast Phase Failure Response: Phase failure and sequence protection action time is less than 0.5 seconds. Versatile Application: Ideal for air conditioning, elevators, pumps, and fans motor control protection. Enclosed Relay Design: Electronic type enclosed relay with micro power load capacity for safety.
