TOMZN 3-Phase 63A/100A Voltage & Current Relay Protector SYN/ASYNC

Complete 3-Phase Protection — Synchronous or Asynchronous, Your Choice.

Three-phase systems demand more sophisticated protection than single-phase setups. The TOMZN 3-Phase 63A/100A Voltage & Current Relay Protector delivers 7 layers of adjustable protection for 3-phase motors, industrial equipment, and commercial panels — with the unique ability to operate in both Synchronous (SYN) and Asynchronous (ASY) modes, giving you precise control over how each phase is managed.

✅ Key Benefits

• SYN & ASY Dual Mode — Synchronous mode: all 3 phases trip and reconnect simultaneously. Asynchronous mode: each phase operates independently — ideal for mixed loads.
• Over-Voltage Protection — Adjustable trip threshold (230–300V) with configurable action time (0.1–30s) and auto-recovery delay (1–500s).
• Under-Voltage Protection — Adjustable lower threshold (140–210V) to protect motors from low-voltage damage.
• Over-Current Protection — Configurable from 1–63A or 1–100A with adjustable action and recovery times.
• 3-Phase Unbalance Protection — Detects dangerous voltage imbalances between phases (20–99V threshold) that can overheat and destroy 3-phase motors.
• Phase Sequence Protection — Detects incorrect phase sequence (ON/OFF configurable) — prevents motors from running in reverse.
• Voltage & Current Calibration — Fine-tune readings with ±9.5% calibration for accurate monitoring.
• Configurable Power-On Delay — Set 1–500s startup delay to protect equipment from surge on power restoration.
