Cam switch 40A, Three-phase starter switch (0,Y,A), base mounting front grey knob black ŁK40-4.831\B03

Starter Switch – Reliability and Versatility in Motor Control

This three-phase cam switch with a 40A current is a robust solution for controlling electric motors, especially in star-delta (0,Y,A) starter circuits. It finds application in both industrial installations and more demanding commercial applications. The design allows for safe and efficient switching of circuits, and the high quality of workmanship guarantees long-lasting and trouble-free operation.

Construction and Application

The cam switch is designed for base (front) mounting and features a high degree of protection IP65, providing resistance to dust and moisture. Made of durable plastic, it is resistant to mechanical damage and environmental factors. Designed for continuous operation at a rated current of 40A and a power of 20kW for AC-3 at a voltage of 400V. Screw connection ensures a secure and stable connection of the wires. The black knob facilitates operation and precise switching of circuits.

Key Advantages

• High reliability: The design based on proven technical solutions guarantees trouble-free operation for a long time.
• Versatility: Possibility of use in various types of electrical installations, especially in three-phase motor starter circuits.
• Resistance to external conditions: IP65 protection rating ensures safe use even in harsh industrial conditions.
• Safety: Rated continuous current of 40A and high surge current resistance provide effective protection of the electrical installation.
• Easy installation: Designed for base (front) mounting, which facilitates integration with existing infrastructure.
• Mechanical durability: Withstands up to 3 million switching cycles, which translates to a long service life of the device.
• Wide operating temperature range: Allows operation in a temperature range from -40°C to +70°C, making it suitable for use in various climates.

User Parameters

The switch has three poles and does not have auxiliary contacts (normally open, normally closed or changeover). The possibility of indirect mounting increases installation flexibility. The housing material is high-quality plastic providing insulation and resistance to mechanical damage. The device does not have a return position to "0", which means that after switching it remains in the selected position until manually returned to the starting position. It is an actuator type "switch" with a knob as a control element.

The rated operating power for AC-3 at 400 V is 20 kW, the rated continuous current (Iu) is 40 A, and the degree of protection is IP65. The device has three poles and is made of plastic.

Remember that choosing the right cam switch is crucial for the safety and reliability of the entire electrical installation. This model offers an optimal combination of functionality, durability and ease of use, meeting the requirements of both professional installers and end users.
