40A rotary switch, direction of rotation changeover switch L-0-P, panel mounting, gray front, black knob SK40-3.8368\P03

Rotary cam switch for panel mounting – reliable load control

This rotary cam switch from Spamel, with a rated current of 40A, is a robust solution for controlling electrical circuits. Designed for panel mounting, it offers convenient change of rotation direction (L-0-P) and is particularly useful in industrial applications where frequent changes in the direction of operation of motors or other devices are required. The front with an IP65 protection rating guarantees resistance to dust and moisture, making it an ideal choice for harsh environmental conditions.

Design and application

The switch is designed for durability and reliability. Made of high-quality plastic, it provides good insulation and resistance to mechanical damage. Designed for indirect mounting, it allows for easy integration with existing installations. The knob makes it easy to operate even with gloves on. It is an ideal element for installers building control panels and for end-users who need a reliable switch in their workshop or factory.

Key features and benefits

• High resistance to external conditions: IP65 protection rating provides protection against dust and water jets, increasing the device's lifespan in demanding environments.
• Intended for high-power loads: Rated operating power for AC-3 is 12 kW at 400V, allowing control of even larger devices.
• Safe use: Made of plastic provides good electrical insulation and minimizes the risk of electric shock.
• Convenient operation: The knob allows intuitive change of rotation direction or circuit disconnection (position 0).
• Solid construction: Designed for frequent use – mechanical durability is 3 million switching cycles.
• Universal mounting: Indirect mounting allows easy adaptation to different panel and machine configurations.
• Wide range of wires: Possibility to connect wires with a cross-section from 4 to 10 mm², providing installation flexibility.
• Compliance with standards: Meets safety standards, guaranteeing safe use.

Technical parameters in practice

The rated continuous current of 40A allows safe use with various electrical devices. The short-circuit current withstood by the switch is 0.7 kA, providing additional safety in the event of a short circuit in the installation. A wide operating temperature range (-40°C to +70°C) allows it to be used in difficult climatic conditions. It is worth paying attention to the tightening torque of the terminals of 1.2 Nm – proper tightening will ensure a stable electrical connection and avoid problems with conductivity.
