Cam switch disconnector 32A, 0-1 switch (4-pole), in OB2 housing with yellow/red lockable front cover ŁK32R-2.8210\OB2ZC

Rotary cam switch – reliable switching in your installation

This four-pole rotary cam switch with a rated current of 32A is a solid solution for frequent circuit switching. Equipped with a 0 position, it provides safe isolation and convenient operation. It is ideal for both industrial and commercial building applications where reliability and durability are required. The OB2 housing with a lockable (yellow/red) front ensures protection against external conditions and facilitates identification of the switch status.

Design and application

A rotary cam switch is a device used to manually switch electrical circuits. The ŁK32R-2.8210\OB2ZC model is distinguished by its complete construction in a housing, which simplifies installation and provides additional protection. Designed for panel mounting, it offers convenient access and intuitive operation. It uses screw connections for the main contacts, ensuring a secure and durable connection of the wires. The use of a knob as the actuating element guarantees precise and smooth switching.

Key features and benefits

• High resistance to external conditions: IP65 protection rating protects against dust and water jets, allowing the switch to be used in harsh environmental conditions.
• Safety of use: The presence of the 0 position allows for complete disconnection of the circuit, ensuring safety during maintenance or repair.
• Durability and reliability: Made of high-quality plastic, the switch is resistant to mechanical damage and ensures long-term operation.
• High switching power: The rated operating power for AC-3 is as high as 17 kW at 400V, allowing it to handle even demanding loads.
• Versatility: The four-pole design means the switch can be used in various three-phase and single-phase applications using two poles.
• Simple installation: The complete device in the housing simplifies installation and reduces the time required to start up the system.
• Mechanical resistance: Designed for intensive use – withstands up to 3 million switching cycles.

Operating parameters

The rated continuous current (Iu) is 32A, making it suitable for protecting various electrical circuits. The conventional rated short-circuit current is 12 kA, providing effective protection against the effects of short circuits. The switch is adapted to operate in a wide range of ambient temperatures (-40°C to +70°C), which increases its versatility. The cross-section of the connection wires is 4…6 mm², allowing connection of wires of different thicknesses.
