40A reversing starter, direction of rotation changeover switch L-0-P, in OB4 enclosure with lockable front ŁK40-3.8368\OB4Z

Universal cam switch for demanding applications

This cam switch with a rated current of 40A is a reliable solution for controlling electrical circuits. Designed for frequent switching, it is ideal for industrial applications, motor control systems and anywhere where a change of rotation direction is required. Model ŁK40-3.8368\OB4Z is characterized by a solid construction and a high degree of protection, which guarantees safe and long-lasting operation. The L-0-P rotation direction changeover switch provides flexibility in circuit configuration.

Construction and operating parameters

The switch is housed in a durable OB4 housing with a closed front, providing protection against external factors and mechanical damage. The IP65 protection class guarantees resistance to dust and water jets, allowing installation in harsh environmental conditions. Screw terminals provide a secure and durable connection of wires with a cross-section from 4 to 10 mm². The device design allows for indirect mounting, and the housing material - plastic - provides good electrical insulation and corrosion resistance. The continuous rated current of 40A and the high switching power (up to 20 kW at 400V) allow for use in circuits with high power consumption.

Safety and compliance with standards

The device meets strict safety standards, including a rated insulation voltage Ui of 690V and withstands impulses of 6kV. The short-time withstand current is 0.85kA, and the making current 1.5kA, providing effective protection against overloads and short circuits. The switch is resistant to vibrations and mechanical shocks, as confirmed by tests in accordance with IEC standards. It also has CE, RU and UA compliance certificates. The mechanical durability of 3 million switching cycles guarantees a long service life even with intensive use.
