Product Description

 

3MPE 6APE Snap Action Both Temperature And Current Protector Bimetal Thermal Protector

 

Technical Parameters

1. Operating temperature range:50~180℃;
2. The tolerance: ±5℃;±7℃ and ±10℃ optional;

3. Trip Off current: 1~40A;
4. Trip off time: 4~10s( or customized)
5. The product portfolio should be able to withstand the 3.0Kg pulling force without loose; terminal and riveting line portions have to withstand 3.0Kg pull force with loose.

 

Construction

1. Appearance: The overall size conforms to the specifications and drawings.

2. Connection Type:Snap connector or riveting wire.

3. Case: Plated Ni and Zn on the mid steel material surface.

4. Sleeving material:Polyester insulation material

 

Special Features

1. Both temperature and current sensitive;

2. Small size, long life and high reliability;

3. High level bimetal ensures that it can withstand the current of normal circuit;

4. The combination of bimetal and heater can action snappily;

5. Increase the PTC heating element of thermal protector, so it has the characteristics of single shot trip, with self holding and time -delay

protection;

6. Terminals are in same direction or opposite direction optional, or customized;

7. Each parts are strict implementation of the European ROHS and REACH environmental standards.

The Design and Working Principle of Thermal Protector

 

1. Both temperature and current sensitive function:

 

1.1 Current overload protection principle: 

The current flows the case terminal, bimetal strip or auxiliary heating wire(which is connected with stationary contact of the bottom board), then the bottom board terminals is connecting to application(such as motor and transformer etc.) in circuit, when the application causes the over-current or locked-rotor current to exceed the prescribed value, the thermal protector cut the power off within the set time, so that the application are protected.

 

1.2 Temperature protection principle:

The current flows the case terminal and bimetal strip, then the bottom board terminals is connecting to application(such as motor and

transformer etc.) in circuit, when the application works abnormally, which causes the ambient temperature to exceed the setting value, the thermal protector cut the power off ,when the ambient temperature will decrease and then the protector will close again.

 

2. Power cutting and time delay protection

Added the PTC heating element

 

2.1 Work-operating

The protector is connected to PTC in parallel, then connected to application in series.When the application is working normally, the current will flow through protector.PTC will not work.

 

2.2 Time delay protection

•When the application works abnormally, which causes the ambient temperature to exceed the prescribed value, the protector will open. Then, the current flows through PTC. Since PTC has a very high resistance, the current assigned to the application will be too flow to start it.Meanwhile, the heat generated by PTC will remain the protector open until the power is unplugged.

 

•After the power is unplugged, the ambient temperature will decrease and then, the protector will close again.
