Cam switch 40A, Disconnector 0-1 (1-pole), front panel mounting, enclosed, yellow/red ŁK40-1.825\P08

Cam switch – reliable circuit switching

This single-pole cam switch with a rated current of 40A is a robust solution for frequent switching of electrical circuits. The enclosed design, intended for front panel mounting, provides convenience and safety in various applications. Made of durable plastic, it is resistant to mechanical damage and environmental influences. Its yellow-red housing facilitates identification and indicates the switching status.

Functionality and application

The cam switch ŁK40-1.825\P08 with position 0 (off) allows for safe disconnection of the load from the power supply. It is designed for indirect mounting, providing flexibility in installation. The rated operating power for AC-3 is 20 kW at 400V, making it suitable for controlling motors and other high-power devices. Screw connection of the main contacts guarantees a secure and durable connection of the wires. The IP65 protection class on the front side provides protection against dust and water jets, which is particularly important in harsh industrial conditions.

Safety and operating parameters

The device meets high safety standards, withstanding a rated insulation voltage U_i of 690V and an impulse withstand voltage U_imp of 6kV. The rated short-time withstand current I_cw(1s) is 0.85 kA, and the rated short-circuit making current I_cm reaches 1.5 kA – providing effective protection of the installation in the event of a short circuit. The switch maintains its properties in a wide range of ambient temperatures, from -40°C to +70°C, both during operation and storage. The possibility of connecting wires with a cross-section of 4…10 mm² ensures compatibility with various types of electrical installations.
