Cam switch 16A, Three-phase starter switch (0,Y,A), \OB7/2 SK16-4.831\OB7/2

Three-Phase Starter Switch – Reliable Control of Your Installation

This 16A cam switch, designed for three-phase systems (0-Y-A), is a solid solution for both professional installers and end-users. The device allows for safe and efficient switching of electrical circuits, finding application in various industrial and commercial installations. Manufactured by the renowned company SPAMEL, it guarantees high quality and long-lasting reliability.

Construction and Application

A cam switch is a device for mechanically switching electrical circuits, enabling the implementation of specific connection programs by rotating the knob. This model, in OB7/2 housing, is particularly useful in applications requiring frequent switching of the load, such as starting three-phase motors or controlling heating devices. The construction based on segments with double cams allows for flexible configuration of the connection program, adapting it to the specific needs of the installation. The possibility of mounting in various configurations – on a panel, base, rail or directly in the enclosure – ensures a wide range of applications.

Key Features and Benefits

• Durability and reliability: Made of high-quality materials, the switch ensures long-lasting and trouble-free operation even in harsh environmental conditions.
• Wide voltage range: Designed to operate with a rated insulation voltage of 690V and an impulse voltage of 4kV, making it a universal solution for many applications.
• Suitable for continuous operation: Rated continuous current of 16A and the possibility of short-term overload ensure stable operation even under heavy load.
• Safety of use: Protection class IP65 guarantees protection against dust and water jets, increasing safety of use in exposed environments.
• Flexible mounting: The possibility of mounting in various configurations (panel, base, rail or in enclosure) facilitates integration with existing infrastructure.
• Compliance with standards: Meets the requirements of PN-EN60947-3 and IEC 60947-3 standards, confirming its safety and quality.
• Resistance to external factors: Exhibits resistance to vibrations, shocks, damp heat and salt mist in accordance with IEC 60068-2-x standards.

Additionally, it is worth mentioning the possibilities of configuring the knob rotation angle (30°, 45° or 90°) allowing to adjust the number of knob positions to specific application needs. The switch is compatible with wires with a cross-section of 1…4 mm², and the tightening torque of the terminals is 0.5 Nm, which facilitates assembly and ensures a secure electrical connection.
