Cam switch disconnector 40A, 0-1 switch (3-pole), in OB13 housing with yellow/red lockable front SK40-2.8211\OB13ZC

Rotary cam switch – reliable switching in electrical installations

This three-pole rotary cam switch with a rated current of 40A is a robust solution for switching electrical circuits on and off. Equipped with an OB13 housing with a lockable front (yellow-red color), it provides safe and convenient operation. It is a complete device, ready for installation, ideal for both professional installers and end users.

Design and application

Rotary cam switches, such as this model, are widely used in low-voltage electrical installations. They can be used as switches, disconnectors, changeover switches and control switches. The segmented design with double cams allows for the creation of various connection programs tailored to specific needs. The ability to obtain cam rotation angles in 30°, 45° or 90° increments allows for precise circuit control. The OB13 housing made of durable PA6 plastic ensures durability and resistance to mechanical damage. In addition, this material is recyclable, which is in line with the principles of sustainable development.

Safety and compliance with standards

The switch meets the requirements of PN-EN60947-3 and IEC 60947-3 standards, guaranteeing a high level of safety. The IP65 protection class of the front protects against dust and water ingress, allowing operation in harsh environmental conditions. The use of screw connections ensures a secure and stable connection of the wires. The device is designed to operate at temperatures from -40°C to +70°C and is resistant to vibrations, shocks and atmospheric factors (salt mist). The housing is equipped with PE and N terminals, increasing the safety of the installation.
