Description

  • [VOLTAGE UNBALANCE PROTECTION] Detects voltage imbalances exceeding 8% to prevent motor damage. The red indicator light activates during phase loss, ensuring quick fault identification and priority response.
  • [PHASE LOSS DETECTION] Monitors dynamic and static phase loss in running or idle states. The red light indicator alerts users to phase failures without requiring specific motor wiring configurations.
  • [LOAD-INDEPENDENT OPERATION] Functions reliably regardless of line current, inrush current, or load nature. Consumes less than 2W while maintaining full performance in all climate conditions.
  • [FAULT RESPONSE DELAY] Incorporates a 1-2 second delay mechanism upon fault detection before relay release, preventing false triggers during temporary voltage fluctuations.
  • [PHASE SEQUENCE PROTECTION] Prevents incorrect L1-L2-L3 connections with yellow light indication. Swapping any two phases corrects the sequence while maintaining compliance with international safety standards.
