40A reversing starter, direction of rotation changeover switch L-0-P, in OB3 enclosure with yellow/red front cover ŁK40-3.8368\OB3C

40A Cam Switch – Reliable Switch for Your Installation

This 40A cam switch from Spamel is a robust solution for controlling electrical circuits. Designed for frequent switching, it is ideal for industrial applications and installations requiring reliability. Model ŁK40-3.8368\OB3 is versatile thanks to the ability to change the direction of rotation (L-0-P) and is supplied in a durable OB3 housing with a yellow-red front, providing high resistance to external conditions.

Design and Application

A cam switch is an element used to manually switch electrical circuits. In this model, the ability to select the L (left), 0 (off) or P (right) position makes it particularly useful in applications requiring a change in the direction of rotation of motors or other devices. The OB3 housing made of plastic provides good insulation and protection against mechanical damage. The IP65 protection rating guarantees resistance to dust and water jets, allowing it to be used even in harsh environmental conditions.

• Application: Controlling motors, machines and other electrical devices requiring a change in direction of rotation.
• Mounting: For surface or indirect mounting (requires additional accessories).
• Application: Industry, workshops, construction and anywhere requiring reliable change of direction of rotation or switching circuits on/off.

Parameters and Benefits

This switch stands out from the competition thanks to its solid construction and high technical parameters. The rated continuous current of 40A and the high switching power (20 kW for AC-3 at 400V) allow for safe and efficient control of most electrical devices. Additionally, the lack of auxiliary contacts simplifies installation in some applications.

• High resistance: IP65 housing protects against dust and water, ensuring long-term operation in harsh conditions.
• Safety: Rated insulation voltage Ui 690V and impulse withstand voltage Uimp 6kV guarantee safe operation.
• Durability: Made of high-quality materials, ensuring long life and reliable operation (mechanical durability: 3 million switching cycles).
• Versatility: The ability to change the direction of rotation L-0-P increases the range of applications.
• Easy installation: Screw connection of the main contacts facilitates the connection of wires with a cross-section from 4 to 10 mm².
