Information

Overload protector is a widely used electrical equipment protection device, mainly used to protect the safe operation of electrical equipment under abnormal conditions such as short circuit and overload. It has the advantages of sensitive operation, simple structure, safety and reliability, and is very easy to use. The following will introduce you in detail how to use the overload protector.

overload protector

First, understand the principle of overload protector

Before using overload protector, we need to understand its working principle and characteristics. The overload protector adopts two protection measures: thermal element and electromagnetic element. When the electrical load current exceeds the rated value, the thermal element is heated and bent to push the trigger mechanism to trip the circuit breaker to achieve the purpose of protecting the electrical appliance. At the same time, the electromagnetic element can quickly respond in the event of a short circuit and cut off the circuit in time, thereby avoiding equipment damage or personal injury accidents.

Second, the correct wiring

Before using the overload protector, it is necessary to perform correct wiring according to the requirements of the circuit diagram, and ensure that the overload protector is connected to other electrical equipment normally. After the wiring is completed, the main power should be turned on first, and then the trial operation and debugging should be carried out.

Third, set protection parameters

The use of overload protector needs to set protection parameters, so that when abnormal conditions such as short circuit and overload occur in the equipment, the power supply can be cut off in time to avoid failures and accidents. Protection parameters usually include rated current, rated quantity, overload capacity, etc., which need to be set according to specific conditions.

Fourth, install the overload protector in a suitable location

The overload protector is usually installed on the side or top of the electrical equipment, and can be installed by spiral wiring or plug-in. The installation location of the overload protector should meet the safety requirements, and avoid damage or misoperation caused by being too far or too close.

Fifth, regular maintenance and overhaul

In order to ensure the normal operation of the overload protector and prolong its life, and to prevent secondary damage or personal injury to electrical equipment, it is necessary to regularly maintain and overhaul the overload protector. Such as removing dust, checking whether the protection parameters meet the requirements, etc.

In short, the overload protector is a very important electrical equipment protection device. During use, attention should be paid to correct wiring, setting of protection parameters, selection of a suitable installation location, etc., to avoid electrical faults and equipment damage. At the same time, regular maintenance and inspection are required to ensure the normal work of the overload protector.
