一、The main technical criteria of protecto

1、Source Voltage: AC110V; 50HZ.

2、Ambient Temperature: －20～60℃.

3、The Contact Rating of Relay: AC250V, max6A,300VA ind.

4、Operating Time of Relay: more than 1×10 times.

5、Operating Point for Protecting: PTC more than 4.5KΩ.

6、Switch Perdurability Time:5min±15％

7、IP Degree of Protection:IP00

二、The Working Process of Protector

The functional block diagram of protector as follows:

he protector mainly make of the power module, the integrate circuit／IC with high-precision timing function and the relay with long-lived, could work in extensive series of operating voltage and work in very hostile environment. Its high performance design meets protecting requirements of all kinds of electric motors.

After the protector is switched on, it operates smoothly. The relay operating and the contact in open circuit when the thermosensitive element PTC reaches normal response temperature, and its resistance is 4.5 KΩ.

The timer start up, after 5 mins, relay operating .the contact in close circuit. When PTC resistance declines to less than 2.5 KΩ. So the protector make purpose for protecting electric motors, avoid over-heat lead to burnning electric motors.
