LW30-40A 4 Position OF CAM SWITCH

LW30-40A 4 Position OF CAM SWITCH DETAILS:

Product overview

LW30-40A/4P is a universal transfer switch, mainly used in AC 50Hz, rated operating voltage below 440V, rated current up to 100A electrical line, can be used as the main switch of ventilation equipment, air conditioning and water pump system, but also can directly control small-capacity AC motor.

Product characteristics

Compact structure: small size, reasonable design, can achieve a variety of functions in a limited space, easy to install and use, especially suitable for electrical control cabinets and other places with high space requirements.

Material selection: The use of high-quality conductive materials and insulating materials to ensure the electrical and mechanical properties of the product, effectively reduce contact resistance, improve electrical conductivity, while enhancing the insulation effect, to ensure the safety of use.

Good insulation: It has good insulation performance, and the insulation distance is greater than other switches of the same kind, which can effectively prevent faults such as leakage and short circuit, improve the reliability and safety of the product, and can be applied to more complex electrical environments.

Finger protection function: Taking into account the safety of the operator, the finger protection function is set to avoid the risk of electric shock caused by finger miscontact in the operation process, which reflects the humanized design concept.

Fast disconnection speed: the contact disconnection speed is faster, can quickly cut off the circuit, effectively reduce the generation of arc, reduce the burn damage to the contact, extend the service life of the product, but also improve the protection performance of the circuit, suitable for DC switch and other occasions with higher requirements for cutting speed.

Technical parameter

Rated current: 40A, can meet the control and protection requirements of electrical equipment within a certain power range.

Number of poles: 4P, that is, four poles, can control and switch four circuits at the same time, which is suitable for circuits that need to control polyphase power supplies or multiple loads.

Rated voltage range: AC 220V-440V, can adapt to different voltage levels of electrical systems, with a wide range of applications.

Mechanical life: generally up to more than 1000 times, under normal conditions of use, can withstand repeated operations, to ensure the long-term stable operation of the product.

Electrical life: usually can reach about 1000 times, to ensure that in the long-term electrical switching process, the contact can maintain good contact performance and electrical conductivity, to maintain the normal circuit on and off.

Product application

Industrial control: In all kinds of industrial production equipment, such as machine tools, cranes, conveyor belts, etc., can be used to control the start and stop of the motor, positive and negative rotation and multi-speed operation, to achieve accurate control and regulation of the production process.

Building electrical: In the electrical system of the building, it can be used to control the operation of ventilation equipment, air conditioning system, water supply and drainage pump, etc., to ensure the comfort of the building environment and the normal operation of the equipment.

Power distribution: can be installed in the power distribution cabinet, as a power switch, to achieve the selection and control of different power supplies or different load circuits, improve the reliability and flexibility of the power system.

Installation and use

Installation mode: Panel installation or guide rail installation can be used. Select the installation mode based on the actual scenario and device requirements. During the installation process, ensure that the switch is firmly installed and correctly connected to avoid faults and security risks caused by improper installation.

Operation method: By rotating the handle to achieve different circuit switching and on-off. When operating, pay attention to the rotation direction and position of the handle to ensure accurate and reliable operation. Before circuit switching, the relevant power supply should be cut off to prevent electric shock and short circuit accidents.

Matters needing attention

It must be installed, operated and maintained by professional electricians, and non-professional personnel are strictly prohibited to operate without authorization to ensure the safety of use.

In the process of installation and use, operation should be strictly in accordance with the product instructions and relevant electrical codes to avoid product damage and safety accidents caused by illegal operations.

Check and maintain the switch regularly, check the contact condition, insulation performance, etc. If there is an anomaly, it should be replaced or repaired in time to ensure the normal operation and service life of the product.
