Feature: Dynamic phase loss, static phase loss protection: refers to the phase failure of any phase when the protected device is in the running state or non-operating state. The indicator light is in the form of red light and priority. Wrong phase protection: A protection measure to prevent the phase sequence of L1, L2, L3 three-phase AC power supply from being connected incorrectly. Instant action. The indicator light is in the form of yellow light. Delay protection: When there is a fault, the monitor will delay after 1~2 seconds, and the relay will release. The protection function of the monitor is not affected by the current of the line or load, the inrush current, the unbalanced current and the nature of the load. Long-term work with full performance and full climate. Power consumption is no more than 2W. There is no requirement for motor wiring when used for motor protection. This product complies with GB/T 14048.1-2000, GB14048.5-2001 eqv IEC60947-1:1999. The EMC of this product complies with the measurement method and permissible value of radio interference characteristics of GB4343-1995. Specification : Model: TG30S 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;
