DNY-M602 motor protection device

Product Overview

The DNY-M602 series motor protection device adopts advanced numerical control technology to prevent motor faults such as short circuit, locked rotor, overload, underload, phase loss, three-phase imbalance, leakage, and temperature rise

Provide protection for obstacles and have functions such as measurement, operation control, diagnostic maintenance, alarm output, etc; This device has powerful functions and can be used for multiple purposes, replacing ammeters, current transmitters, and thermal overloads

Relays, time relays, Lan Dian relays, etc. The human-machine interface is clear, with good operability and high detection accuracy, ensuring the accuracy and reliability of actions. Equipped with RS485 remote communication interface

The port supports the MODBUS-RTU protocol, making it easy to form network systems and providing scientific and effective on-site protection and measurement units for industrial production process control.

Suitable for chemical, petrochemical, and building materials industries. Metallurgical, municipal, environmental protection, power and other industrial motors, as well as three-phase power feeding systems.

Technical Specifications

1. Inverse time limit protection: This protection device has overcurrent inverse time limit delay protection function.

2. Light load protection: When the current value is less than the light load protection set value, the protection device will operate within 30 seconds.

3. Overcurrent protection: The protection current can be set arbitrarily, and when the current value is greater than the set value, it will act according to the action characteristic curve.

4. Phase failure protection: When the motor power supply is disconnected (the three-phase current imbalance value during production can be set to 60% according to user requirements), the protection device will operate within 3 seconds.

5. Locked rotor protection: When the operating current of the motor is greater than 5 times the set value, the protection device will operate within 2 seconds.

6. Leakage (grounding) protection: When the leakage current exceeds the set value, the protection device will operate within 3 seconds.

7. Short circuit protection: When the current of any phase reaches 81e, the protection device will activate within 2 seconds.

8. Start delay time: adjustable within 1-99 seconds.

9. Star delta conversion time: The star delta conversion time is less than the startup delay time by 3 seconds.

10. 4-20mA current output accuracy: 0.3% FS, 20mA corresponds to twice the rated value (optional)

11. Output relay contact capacity: 250VAC7A.

12. Current display error: ≤ 1.5%.

13. It has a startup delay function: to avoid separating the action time of starting high current and overcurrent.

14. Equipped with RS-485 source search port, supporting international MODBUS-RTU protocol for easy network system composition
