Digital Electronic Overload Relay 380V (0.5-6)A

📖 Description:

• A highly reliable digital electronic overload relay designed for motor protection. It effectively safeguards motors from overload, phase failure, phase imbalance, and overheating, ensuring stable operation and extended lifespan. This relay offers precise current sensing, adjustable settings, and fast response time, making it ideal for industrial automation and heavy-duty applications. Its compact design and user-friendly interface allow for easy installation and operation, providing superior protection for motors in various environments.

⚙️ Features:

• ■ Compact Design
  ■ Overload / Phase Loss / Locked Rotor protection
  ■ Accurately display the working current (the highest current of L1 and L3) through the front panel LED display
  ■ When trip occurs, the cause is displayed on the LED window
  ■ Phase loss protection (3 seconds)
  ■ Convenient application: Selective use of single-phase (1P) and three-phase (3P) by DIP switch.
  ■ Optional contact output [fail-safe (N)/non-fail-safe (R)]: simplify the adjustment of the contact state
  ■ Easy installation due to both Din Rail and Panel Mounting

🛠️ Applications:

• – Low Voltage Induced Electromotor (600V Level)
  Protective Relay
  – Break-Down Watch Current Relay
  – Alternative Replacement for the Existing Relay

Protetcion

• Protective Item Operating (Trip) TimeOver-Current = O-TIME

  Phase Loss = 3 sec.

  Locked Rotor = After D-time（Operating current> 200% of set current）

Set

• After the installation is complete the settings as follows.Set knob: D-TIME(Delay Time) Set two to three seconds longer than the motor starting time.

  Set knob: O-TIME(Over-current run time) Set less than the motor’s endurance time with over-current.

  Set knob: Load(Rated Current) Set over 110% of the motor’s rated current of under 120% of its operating current
