Disconnect switch 40A, Isolator 0-1 (3-pole), in OB2 enclosure with yellow/red front ŁK40-2.8211\OB2C

40A Cam Switch – Reliable Circuit Disconnection

This three-pole cam switch, designed for a rated current of 40A, combined with the OB2 enclosure, is a robust solution for manual switching of electrical circuits. It is suitable for both industrial installations and applications requiring frequent disconnection of devices, e.g. during machine servicing. The 0 position design provides additional safety during maintenance and repair.

Solid Construction and High Protection

The enclosure made of plastic provides good insulation and resistance to mechanical damage. The IP65 protection rating guarantees protection against water jets and dust, making it suitable for use in harsh environmental conditions. The use of screw connections ensures a secure and durable connection of the wires.

Key Features and Parameters

This switch is characterized by a continuous rated current of 40A, allowing for safe loading of the installation. The rated operating power at AC-3 (400V) is 20 kW, enabling operation of devices with significant power. The enclosure has an IP65 protection rating, providing high resistance to the ingress of solids and water. The three-pole design is ideal for three-phase electrical installations, and the enclosure material – plastic – guarantees lightness and corrosion resistance. The presence of the 0 position increases safety during servicing and maintenance of devices. The device is also very durable - it withstands as many as 3 million switching cycles, and the range of accepted connection wire cross-sections is 4…10 mm².

Application and Installation

The cam switch finds application in:

• Disconnecting electric motors during servicing.
• Switching off the power supply to individual circuits for repair or maintenance.
• Construction of electrical switchboards in industrial plants.
• Installations requiring manual control of circuit switching on/off.

The switch is easy and intuitive to install thanks to screw connections, making it easy for both installers and end users. Remember to observe appropriate safety rules when working with live equipment.
