- The Phase Sequence Lack Phase Relay TG30S is a three-phase phase sequence protector for elevator motors. It detects phase sequence and phase loss with high precision to support stable operation and protect the motor. - Compatibility and model: Suitable for 220V and 440V elevator motors, TG30S type three-phase phase sequence protector. - Core function: Protects elevator motors from damage caused by incorrect phase sequence or missing phase, helping prevent unexpected motor faults and downtime. - Performance: High precision phase sequence detection and reliable protection against phase-related faults to maintain smooth elevator operation. - Package: Includes 1 piece for easy integration into existing elevator electrical systems. - Use scenarios: - New elevator installation or control panel upgrade requiring reliable phase protection for 220V/440V motors. - Retrofit in facilities with unstable power or frequent phase loss events to shield motors from damage. - Maintenance or servicing of multi-motor elevator systems where consistent phase sequencing is critical to prevent start-up faults. - Why it matters: Clear protection against phase sequence errors and phase loss preserves motor life, reduces maintenance costs, and enhances overall elevator system reliability.
