Cam switch 63A, 1-0-2 switch (3-pole), base mounting front grey knob black ŁK63-3.8380\B03

Rotary switch – reliable switching in electrical installations

The rotary switch LK63-3.8380\B03 is a robust device designed for safe and convenient switching of electrical circuits. Designed for base mounting, it offers reliable operation in a wide range of applications – from industrial installations to commercial buildings. Made of high-quality plastic, it provides durability and resistance to mechanical damage. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates well the starting of devices with a motor.

Construction and application

This 3-pole rotary switch with a "0" position allows disconnection of the circuit in a visible and secure manner. It is intended for installations where frequent switching of the load is required, as well as for applications where visual control of the connection status is important. Thanks to the possibility of mounting on a rail or directly on a base (depending on the version), it offers flexibility in choosing the installation method. Equipped with screw connections, it ensures a secure and durable connection of wires with a cross-section of 4-10 mm². The IP65 degree of protection guarantees protection against dust and water jets, making it an ideal solution for environments with increased humidity or dust.

Key features and benefits

• High mechanical resistance: The housing made of durable plastic ensures long-term operation even in difficult conditions.
• Safety of use: A clear "0" position and a high degree of protection IP65 minimize the risk of electric shock and ensure safe operation.
• Universal mounting: The possibility of mounting on a rail or directly on a base increases installation flexibility.
• High rated power: Rated continuous current of 63A and rated switching power of 20 kW (AC-3, 400V) allow operation of demanding loads.
• Durable construction: Designed for 3 million switching cycles, which guarantees long device life.
• Resistance to external conditions: A wide range of operating temperatures (-40°C to +70°C) allows use in various environments.
• Application in difficult conditions: IP65 protection degree protects against dust and water jets, making it an ideal solution for environments with increased humidity or dust.

The rotary switch LK63-3.8380\B03 is an optimal solution for professionals and end-users looking for a reliable and durable device for switching electrical circuits. Its solid construction, high technical parameters and universal mounting make it perfect for various industrial and construction applications.
