Cam switch 63A, Three-phase starter switch (0,Y,A), in OB3 enclosure with yellow/red lockable front. ŁK63-4.831\OB3ZC

Three-phase cam switch – reliable switching in your installation

This 63A cam switch, designed for operation in three-phase systems (0, Y, A), is a solid solution for demanding applications. Manufactured by the renowned company Spamel, it ensures safe and efficient switching of electrical circuits. The product is supplied in a durable OB3 housing with a front that locks in yellow and red, increasing safety and facilitating identification.

Design and application

A cam switch is a rotary device, ideal for switching currents on and off in low-voltage electrical installations. It can be used as a switch, disconnector, changeover switch or control switch. The design with double cams allows for the creation of various connection programs depending on the position of the drive knob. The OB3 housing provides protection against external factors and guarantees safe operation in harsh industrial conditions. The IP65 degree of protection means resistance to dust and water jets, allowing it to be used even in humid environments.

Key features and benefits

• High reliability: Made of high-quality materials, ensuring long-lasting and trouble-free operation.
• Versatility: Designed for 0-Y-A (star-delta) systems, making it an ideal solution for a variety of applications.
• Safety: OB3 housing with a locking front provides additional protection against accidental contact with conductive elements.
• Durability: The housing material – plastic – guarantees resistance to mechanical damage and corrosion.
• Suitable for continuous operation: Rated continuous current of 63A and high rated operating power for AC-3 (20 kW) allow for intensive use without the risk of overheating or failure.
• Easy installation: Designed for indirect mounting using screw connections, which facilitates installation and maintenance.
• Wide operating temperature range: The ability to operate in a temperature range from -40°C to +70°C ensures reliable operation even in extreme conditions.

Technical parameters in practice

The rated continuous current of 63A and the rated switching power of 20 kW at 400V demonstrate the high efficiency of this switch. The short-time withstand current of 1.2 kA provides additional safety in the event of short circuits or overloads. The IP65 degree of protection guarantees protection against dust and water jets, which is particularly important in industrial environments. Mechanical durability of 3 million switching cycles confirms the high quality of workmanship and long service life of the device.
