LW30-40A 3 Position OF CAM SWITCH

LW30-40A 3 Position OF CAM SWITCH DETAILS:

Technical parameter

Rated voltage: Applicable to the voltage range of 220V-440V, which can meet the power supply voltage requirements of most common electrical equipment.

Rated current: The rated current of 40A enables it to carry a certain power load, which can meet the on-off control requirements of equipment such as small ventilation equipment, some air conditioning systems, and small power pumps.

Mechanical life: generally up to 1000 times, under normal conditions of use, to ensure a long period of stable operation.

Electrical life: usually 1000 times, that is, the number of times that can be reliably operated on and off under specified electrical conditions.

Product structure and characteristics

Compact structure: small size, less space, easy to install and use in a variety of electrical control cabinets, distribution boxes and other limited space, can effectively save installation space, reduce the overall volume of equipment.

Good insulation: The use of high-quality insulating materials and advanced insulation technology, with good insulation performance, can effectively ensure electrical safety, prevent leakage, short circuit and other accidents, improve the reliability and stability of the equipment.

Fast disconnection speed: It can quickly cut off the circuit, which is of great significance for some loads or circuits that need quick protection, such as when the motor short-circuit, overload and other faults occur, it can quickly cut off the power supply, reduce the damage to the equipment, and also isolate the fault circuit in time to prevent the expansion of the influence of the fault.

Easy to operate: the handle is flexible, comfortable to feel, easy to operate and control, and has a clear gear indication, which can clearly display the on-off state of the switch, convenient for users to operate and maintain.

Strong scalability: you can add other contact blocks on the 3-pole standard block without removing the switch to meet the various control needs of different users and achieve more complex circuit control functions.

Application field

Electrical control: widely used in various electrical control systems, such as ventilation equipment, air conditioning system, water pump system, etc., can be used as the main switch to start and stop the equipment control, to achieve centralized management and control of the equipment.

Motor control: It can directly control the operation of small-capacity AC motor, realize the control functions of positive and negative rotation, start and stop of the motor, and is widely used in some small machining equipment, power tools and other fields.

Overall dimensions and mounting dimensions

Different installation methods have different dimensions and installation dimensions. Taking panel installation as an example, the external dimensions of LW30-40/3P are about 50mm×64mm, and the installation dimensions are 16mm, 64mm, 67mm, 48mm, 20mm and 4.2mm.

Precautions for use

Professional operation: The installation, operation, and maintenance must be performed by qualified electricians to ensure correct and safe operations and prevent electrical accidents caused by misoperations.

Power off operation: When the switch is repaired, maintained or replaced, the power supply must be cut off first, and necessary power off and insulation protection measures must be taken, such as hanging "Do not close" signs, using insulation tools, etc., to prevent electric shock accidents.

Regular check: Check the switch regularly, including appearance check, contact check, insulation resistance measurement, etc., to discover and handle potential faults in time to ensure the normal operation of the switch.

Reasonable selection: When selecting LW30-40A/3P switch, reasonable selection should be made according to the current, voltage, power and other parameters of the actual load to ensure that the rated parameters of the switch can meet the requirements of the load and avoid the overload damage of the switch due to improper selection.
