63A Cam Switch, Three-phase reversing starter switch, in OB18 enclosure. SK63-5.8538\OB18

Cam switches – reliable control and circuit protection

Cam switch SK63-5.8538\OB18 is a three-phase motor starter switch, designed for frequent switching of loads and changing the direction of rotation of motors. Mounted in OB18 housing, it provides solid protection and ease of use. This device finds application both in industrial installations and in workshops, where reliability and safety are required.

Construction and application

This model combines the function of an isolating switch with the ability to control three-phase motors. The segmented construction allows for flexible configuration of the switching program, adapting it to the specific needs of the application. The knob's step angles of 30°, 45° or 90° (in the SK63 model) allow for precise setting of the desired configuration. This switch is particularly useful in applications requiring frequent changes in motor direction, such as in construction machinery, agricultural equipment or production lines. The possibility of mounting in OB18 housing increases resistance to environmental conditions and provides additional safety.

Advantages and product features

• Versatility: Ability to create different switching programs thanks to the segmented construction.
• Durability: Compliance with PN-EN 60947-3 and IEC 60947-3 standards guarantees high quality and reliability.
• Safety: Protection class IP65 (in the housing) protects against the influence of external factors such as dust and moisture.
• Durability: Silver-plated contacts minimize transition resistance and ensure long-term operation of the device.
• Flexible mounting: Availability of various mounting methods (to the panel, base-rail, in the housing) facilitates integration with existing installations.
• Application in harsh conditions: Intended for indoor use in environments with 3 degrees of pollution (industrial).
• Rated current: 63A – suitable for most industrial and workshop applications.
• Corrosion protection: Metal elements protected with an electrolytic coating eliminate oxidation.
• Wide operating temperature range: From -40°C to +70°C ensures reliable operation even in extreme conditions.

Thanks to this, the cam switch SK63-5.8538\OB18 is an optimal solution for professionals looking for a reliable and versatile device for controlling three-phase motors and protecting electrical installations.
