63A cam switch, direction of rotation changeover switch L-0-P, in OB16 housing with yellow/red front. SK63-3.8368\OB16C

Cam switch – reliable control of motors and devices

This 63A rated cam switch is a robust solution for frequent switching of loads, especially in applications involving electric motors. Designed for reversing direction of rotation (L-0-P), it is suitable for both industrial installations and workshops. Thanks to the complete OB16 housing and clear front marking (yellow/red), installation and identification are quick and intuitive.

Design and application

The cam switch SK63-3.8368\OB16C is designed to operate with AC-3 loads up to 18 kW at 400V. Its construction based on durable plastic ensures resistance to mechanical damage and environmental conditions. The IP65 protection rating guarantees safe use even in harsh conditions, protecting against dust and water jets. The switch with the "0" position allows for safe disconnection of the circuit, and the lack of return to the "0" position ensures setting stability. Screw connection type provides a secure and durable connection of wires with a cross-section from 6 to 16 mm².

Advantages for the installer and end user

• Versatility: Ideal for controlling motors, pumps, fans and other devices requiring frequent switching.
• Durability: Made of high-quality materials, resistant to mechanical damage and external factors.
• Safety: IP65 protection rating provides protection against dust and water, minimizing the risk of failure and electric shock.
• Easy installation: Complete OB16 housing facilitates installation and saves time. Clear front marking makes it easy to identify the switch function.
• Operation in harsh conditions: Wide operating temperature range (-40°C to +70°C) allows use in demanding industrial environments.
• Reliability: Designed for a large number of switching cycles (3 million), guaranteeing long-term trouble-free operation.
• Rated current: Rated continuous current at 63A allows operation of most standard industrial applications.
• Protection: Provides effective protection against overload and short circuit – like most circuit breakers in this class.

Usage parameters

The switch is designed to operate at an insulation voltage of 690V and withstands an impulse voltage of 6kV. The short-time withstand current is 1.2 kA, and the switching capacity 0.7 kA, providing additional safety for the installation. It meets the requirements of EN 60947-1 standard regarding pollution degree 3 and has protection class II in OB housing. The device is resistant to vibrations and mechanical shocks according to IEC 60068-2-6 and IEC 60068-2-27 standards.
