FEATURES

»

【Comprehensive Protect】The Phase Sequence Protector offers robust dynamic and static phase loss Protect, ensuring devices operate safely under varied conditions. The visible red indicator light alerts users during phase failures for immediate action.

»

【Incorrect Phase Prevention】With innovative technology, the 3-Phase Sequence Relay Protector prevents incorrect phase connections in L1, L2, and L3 three-phase systems. The quick-response yellow indicator light signifies instant activation, preventing costly equipment damage.

»

【Voltage Monitoring】The voltage phase sequences protector provides voltage unbalance Protect, which triggers if voltage imbalance exceeds 8%. A red indicator shows potential threats, maintaining the safety and efficiency of connected devices.

»

【Delay Mechanism】Equipped with a smart delay feature, the display adjustable voltage Protect relay allows for a 1-2 second buffer during fault conditions, enabling careful management of power systems. This ensures both reliability and longevity under heavy loads.

»

【High Efficiency】Designed for continuous operation, the3 phase multi function protector functions effectively regardless of load nature or inrush currents. With minimal energy use (≤2W), it ensures optimal performance in diverse environmental conditions.

DESCRIPTIONS

Description: The TG30S Phase Sequence Protector is essential for safeguarding three-phase AC systems, operating between 220-440V. With innovative Protect features including dynamic phase loss, incorrect phase prevention, and voltage unbalance monitoring, it ensures operation. Specification: Model: TG30S Voltage: 220-440V AC Standards: GB/T 14048.1-2000, GB14048.5-2001 IEC60947-1:199 Package list: 1 x Phase Sequence Protector Note: The actual product color may deviate from the photo due to light. There may be a slight deviation in the measurement of product. Working status: 1. L1, L2, L3 three-phase wiring is correct, the monitor green light is on, the relay is closed; if the phase sequence is wrong, the monitor yellow light is on, just exchange any two phases of L1, L2, L3 three phases, the monitor will Can recognize the phase sequence and work normally. When the protected device is working normally, the yellow light is on, and when the relay does not pick up, it should be regarded as misconnection of the external line phase sequence, and the monitor has the function of preventing misconnection Protect; 2. When the L1, L2, and L3 phases are out of phase, the red light is on, the green light is off, and the relay is released; when the voltage is normal, the green light is on and the relay is closed; 3. L1, L2, L3 are connected to three-phase AC voltage, NO and COM are normally open contacts; NC and COM are normally closed contacts. Use wire to connect the terminal block directly.
