一The main technical criteria of protecto
1、Source Voltage: AC110V; 50HZ.
2、Ambient Temperature20～60℃.
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 4.5K.
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:
The 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 K.
The timer start up, after 5 mins, relay operating .the contact in
close circuit. When PTC resistance declines to less than 2.5 K. So
the protector make purpose for protecting electric motors, avoid
over-heat lead to burnning electric motors.
