Product Description:
The TG30S Phase Sequence Relay safeguards 3-phase systems (220-440V AC) against phase loss, reverse sequencing, and voltage imbalances (>8%). Featuring instant fault indicators and 1-2s delay release, it ensures compliance with IEC60947-1 standards for industrial motors, CNC machines, and HVAC systems.

Specification:
Model: TG30S
Voltage: 220-440V AC
Meet the standard: GB/T 14048.1-2000, GB14048.5-2001 eqv IEC60947-1:199

Package list:
1 * 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 protection;
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.
