Brief Introduction of Auto-start relay
1, Background Information
In the fields of petroleum, chemical, metal, electricity industry, double power supply feed electric energy to important motor loads normally. When one power supply fails, another will be switched on to restore electric power supply. In this way, it can ensure that important motor loads keep running continuously. For motor loads, contactors are usually applied to control motor. During power changeover or power instant shaking, it can be realized for important motor to start automatically by auto-start relays controlling contactors

2, product descriptions
BT-DZQ auto-start relays use advanced electronic digital and analog technologies to integrate various functions into one relay. It is equivalent to conventional electromagnetic relay in physical, but its function is much more powerful in theory.

It can apply to control circuit of FUSE & ConTACTER of motor. It can eliminate motor halt failure due to voltage instant disappear. When power instant shaking or normal power changeover happen, it will control motor to startup again without human manipulation.

Its main characteristics:
1. Individual and independent by one relay to one motor
2. Modular and standard, exchangeable
3. External module; No any change on motor inherent control way.
4. No any effect on motor in case relay failure itself
5. Imitation test device taken with
