63A cam switch, direction of rotation reversing switch L-0-P, in OB4 enclosure with lockable front plate ŁK63-3.8368\OB4Z

Cam switch for demanding applications

This cam switch with a rated current of 63A is a reliable solution for switching electrical circuits, especially in applications requiring a change in the direction of rotation. Model ŁK63-3.8368\OB4Z, equipped with an L-0-P switch, is designed for durability and safety, making it an ideal choice for both professional installers and end users. The OB4 housing with a lockable front provides protection against external conditions and increases safety.

Construction and operating parameters

The switch is characterized by a solid construction based on plastic, providing good insulation and resistance to mechanical damage. Its design allows for safe operation in a wide range of ambient temperatures – from -40°C to +70°C. The rated power for AC-3 is 20 kW at 400 V, confirming its ability to handle significant loads. The continuous rated current Iu is 63 A, and the rated short-time withstand current Icw(1s) is 1.2 kA – parameters guaranteeing stable operation even in the event of overloads. The IP65 protection class provides protection against dust and water jets, which is particularly important in harsh industrial conditions.

Installation and application

The cam switch is designed for indirect mounting and screw connection of wires with a cross-section from 4 to 10 mm². This makes the installation simple and quick. The L-0-P switch allows changing the direction of rotation of electric motors, which finds application in many industries – from production to building automation. The possibility of use in AC-3 and AC-4 circuits makes the switch universal and can be used in various applications. Additionally, the lack of normally open and normally closed auxiliary contacts simplifies electrical diagrams and reduces the risk of errors during installation.
