Cam switch 63A, circuit switch 0-1-2-3, \P01 ŁK63-2.8445\P01

Universal cam switch for switchboards and industrial installations

This 63A cam switch, designated 2.8445, is a reliable device designed for connecting and disconnecting electrical circuits. Its design allows operation in 0-1-2-3 configuration, making it a versatile solution for both installers and end-users. The device is particularly useful in applications requiring frequent circuit switching, such as machine controls, power distribution boards, or lighting systems.

Construction and application

The switch is designed for rail mounting, making it easy to integrate with existing installations. Made of durable plastic, it provides good insulation and resistance to mechanical damage. The IP65 protection rating guarantees protection against dust and water jets, allowing it to be used in harsh environmental conditions. The ability to choose different front versions (P01, P02, P03, P04, P07, P08, P09, P10) allows the switch to be adapted to specific application requirements – from simple solutions with a nameplate to variants lockable for increased security.

Key features and benefits

• High reliability: Designed for continuous operation at a rated current of 63A and high switching power (up to 20 kW in AC-3), it ensures stable and safe operation of the installation.
• Versatility: The 0-1-2-3 configuration option makes it suitable for a wide range of applications – from simple lighting circuits to more complex control systems.
• Safety: IP65 protection protects against external factors, and the ability to use a front lockable with a padlock increases safety.
• Easy installation: The rail mounting design simplifies and speeds up installation.
• Durability: Made of high-quality materials guarantees a long service life (up to 3 million switching cycles).
• Wide operating temperature range: Allows operation in harsh temperature conditions (-40°C to +70°C).
• Compliance with standards: Meets the requirements of PN-EN 60529 and IEC 60068 standards regarding resistance to vibration, shock and environmental factors.

Technical parameters in practice

A continuous rated current of 63A and high switching power (20 kW AC-3) allow the switch to be used in demanding industrial applications. The short-circuit withstand current of 1.2 kA provides additional safety in the event of overloads or short circuits. The ability to connect cables with a cross-section from 4 mm² to 10 mm² provides flexibility in selecting the appropriate power cables. The rated insulation voltage Ui is 690V and the impulse voltage Uimp is as high as 6kV, guaranteeing safety even in the most demanding operating conditions.
