Product Description:

■ gG NH/NT Fuse-links
NH Protection

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:The main parameters of the fuse selection
The fuse must be able to break the fault circuit without breaking the surrounding circuit.
Q:What are the hidden faults of the automatic reset fuse?
Can automatically reset the fuse, in fact, before N years already have, but applied in other areas, and now the field of electric faucet has emerged some unprofessional manufacturers claim to use the domestic first fuse automatic reset technology
Q:If it is possible, is it possible to have an electric shock?
Before the test table did not? 170V voltage should not be so low! Standard requirements: for 220V single-phase power supply
Q:According to the breaking speed, can be divided into
Medium-speed fuse (generally indicated by M)
Q:Is the fuse blown depending on the size of the current flowing through it?
This shows that the fuse can only be placed in the operating voltage is less than or equal to the rated voltage fuse circuit.
Q:The fuse is to prevent the circuit
The fuse is in series in the circuit, and its resistance is slightly larger than the wire, once the circuit has a short circuit,
Q:Fuses can be divided into high-voltage fuses and low-voltage fuses.
the protection of the voltage transformer fuse, the protection of the power capacitor fuses, protect the semiconductor components of the fuse,
Q:Is the fuse the capacitor
the traditional fuse is a larger resistivity, lower melting point of the metal or alloy, through the excessive current, the fuse heat blow.
Q:What is the fuse of the fuse?
Molten tube is a melt shell, made of heat-resistant insulation material, both in the melt
Q:The difference between the fuse gG and the aR
in addition, in the DIAZED-fuse also marked "slow motion" and "fast action", IEC / CEE / DIN VDE have made this provision (DIN is the German national standard code, similar to the Chinese national standard number VDE is the world's leading certification body
