Voltage Measurement Switch in Enclosure – Reliability and Functionality

This cam switch, with a rated current of 63A, is a solid solution for switching electrical circuits. Made of plastic, in a durable OB3 enclosure, it provides safety and durability even in demanding conditions. Designed for panel mounting, it is ideal for both professional and home use.

Construction and Application

Cam switch ŁK63-4.883\OB3 is a device used for manual switching of electrical circuits. The design with a knob ensures convenient and precise operation. Particularly useful in applications requiring frequent circuit configuration changes, e.g., in measurement systems or when testing devices. The IP65 protection degree guarantees resistance to dust and moisture, making it suitable for operation in harsh environmental conditions.

Key Features and Benefits

• Durable construction: The housing made of high-quality plastic provides resistance to mechanical damage and external factors.
• High resistance to weather conditions: IP65 protection protects against dust and water jets, allowing operation outdoors or in damp rooms.
• Suitable for high loads: Rated continuous current of 63A and the ability to switch loads up to 20 kW (AC-3, 400V) allow for use in demanding industrial and home applications.
• Safety of use: Provides effective electrical insulation (690V) and withstands impulse voltages up to 6kV, protecting the installation and users.
• Easy installation: Designed for panel mounting using screw connections of the main conductors.
• Versatility: Can be used in various types of electrical installations – from home to industrial.
• Durability: Mechanical endurance of 3 million switching cycles guarantees a long service life of the device.

Technical Parameters in Practice

The rated AC-3 switching power of 20 kW at 400V voltage means that this switch can easily handle electric motors with a power of up to 20 kW connected to a three-phase network with a voltage of 400V. The rated continuous current of 63A allows for safe powering of devices drawing this current for a long time without the risk of overheating or damaging the switch. Vibration and shock resistance (compliant with IEC standards) ensures stable operation even in environments with high vibration intensity or exposed to accidental impacts.
