1. Product Description:

Is a non resettable disposable thermal protection device, low melting point alloy type RH, RF, RS series and organic chemistry type ry series, (such as electric fan, a motor, a transformer, electric cooker, the electric frying pan, disinfection cabinet, electric heating thermos, etc.). Fuse the temperature fuse in the equipment line, when the equipment does not work properly and lead to the temperature rise to set the protection value, the temperature fuse action to cut off the circuit, to prevent the safety accident.

 

2. Product Characteristic:

The product has a compact structure, good sealing performance, high sensitivity and reliability of action, low impact of electric current and vibration resistance, which is mainly used in the thermal protection of household appliances and industrial equipment.

Q:What are the precautions for using the fuse?
fuse melt according to the requirements of the use of matching melt, not allowed to arbitrarily increase the melt or use other conductors instead of the melt
Q:What is the best material for electric brake fuses?
accompanied by rising current, and the rising current may damage some important devices in the circuit or expensive devices, it may burn Circuit and even cause a fire
Q:What is the fuse often used?
the second part of the electrode, usually two, it is an important part of the melt and circuit connection, it must have Good conductivity, should not produce a significant installation of contact resistance
Q:Fuses are generally not overloaded.
Our fuse in the actual work is used for short circuit protection.
Q:What material is used for the fuse
the bracket part of the fuse melt are generally slender and soft, the role of the bracket is to melt the three parts and become rigid as a whole easy to install,
Q:Fast break fuse and slow cut fuse difference
Purely resistive circuit (no or little surge) or need to protect the IC and other sensitive devices in the circuit must use fast-blow fuse
Q:The main parameters of the fuse selection
The current rating indicates the current carrying capacity of the fuse under a set of test conditions
Q:When selecting a fuse, you must consider several elements
That is, if the circuit voltage is 125V, then the choice of the rated voltage 125V and 250V fuse can be used. If the circuit voltage is 250V, it can only use 250V fuse, and can not use 125V fuse.
Q:What material can be used to make fuse fuse
can be made smaller than the melting point of the melting point of small melt
Q:The fuse is to prevent the circuit
the circuit will produce a lot of current through the fuse, the fuse will heat cut off the power to achieve the role of protection circuit to prevent the circuit
