32A changeover switch, direction of rotation switch L-0-P, in OB3 enclosure. ŁK32R-3.8368\OB3

Cam switch for demanding applications

This 32A cam switch, with a L-O-P direction of rotation changeover switch, is a reliable solution for controlling motors and other electrical devices. Manufactured by the renowned company SPAMEL, it combines a solid construction with functionality, ensuring safe and efficient operation in various conditions. Designed for both industrial applications and electrical installations in buildings.

Construction and application

The cam switch allows for manual switching on and off of electrical circuits, while also offering the possibility of changing the direction of motor rotation. This makes it widely used in controlling various devices, such as pumps, fans, gates or conveyors. The OB3 housing made of plastic provides protection against external factors (IP65), allowing for installation in environments with increased humidity or dust. Durable screw connections guarantee a secure and lasting connection of wires.

Advantages and characteristic features

• High resistance to external conditions: IP65 protection class ensures safe use even in difficult environmental conditions.
• High rated power: The rated power for AC-3, 400 V is 17 kW, allowing control of devices with significant power.
• L-O-P switch: Allows changing the direction of rotation of the device, increasing the functionality of the installation.
• Solid construction: Made of high-quality materials, guaranteeing long-lasting and reliable operation.
• Safety: Meets the requirements of PN-EN60947-3 and IEC 60947-3 standards, ensuring safe use.
• Complete device: Supplied in a complete OB3 housing, ready for mounting.
• Versatility: Suitable for use in enclosed spaces with a degree of pollution 3 (industrial application) at temperatures from -40°C to +70°C.
• No return to position 0: Ensures stable maintenance of the selected switch position.

User parameters

The rated continuous current (Iu) is 32A – this is a key parameter when selecting the switch for a specific circuit. The three-pole construction allows controlling three-phase motors or other devices requiring switching of all three phases. The lack of normally open and normally closed auxiliary contacts means there are no additional possibilities for signaling the switch status – the focus is on the basic function of changing the direction of rotation and switching the circuit on/off. The switch is designed for direct mounting – it does not require additional mounting elements or intermediate adapters.
