Cam switch 32A, Direction of rotation changeover switch L-O-P, in OB2 housing with yellow/red lockable front plate ŁK32R-3.8368\OB2ZC

Rotary cam switch for changing the direction of rotation

This rotary cam switch, with a rated current of 32A, is a reliable device designed for frequent switching of electrical circuits. It finds application in controlling motors, machines and other devices requiring a change in the direction of rotation or circuit selection. The L-O-P (left-0-right) model provides flexibility in configuration and control.

Construction and application

The switch is made of durable plastic, which guarantees its durability and resistance to mechanical damage. The OB2 housing with a yellow and red locking front provides high protection against external factors (IP65), making it an ideal solution for use in harsh industrial conditions. It is designed for mounting on a panel or in control cabinets. It uses screw connection for the main contacts, which ensures a secure and stable connection of the wires.

Key features and benefits

• Application: Specifically designed for changing the direction of rotation of three-phase motors, but also suitable for applications requiring the selection of one of several circuits.
• Durability: Made of high-quality materials, resistant to mechanical damage and environmental factors.
• Safety: IP65 protection rating guarantees protection against dust and water jets – ideal for working in workshops, production halls or outdoors.
• Efficiency: The rated operating power for AC-3 is 17 kW at 400V, which allows operation of devices with significant power.
• Versatility: It has 3 poles, which allows its use in various electrical circuit configurations.
• 0 Position: The presence of the "0" position allows for safe disconnection of the circuit and disconnection of the device from the power supply.
• Easy installation: Designed for indirect mounting with screws, which facilitates installation and replacement.
• Wide temperature range: The ability to operate in a wide range of ambient temperatures (-40°C to +70°C) ensures reliability in various climatic conditions.

Operating parameters

The rated continuous current (Iu) is 32A, which means that the switch can safely operate with a load of this intensity for a long time. The conventional rated short-circuit current is 12 kA – a parameter important for ensuring the safety of the installation in the event of a short circuit. The switch has a C characteristic, which means that it allows for short-term overloads without triggering the protection – useful when starting devices with an electric motor that generate a high starting current.
