Cam switch disconnector 100A, 1-0-2 switch (4-pole), in OB18 enclosure. SK100-4.8396\OB18

Universal Rotary Disconnector 100A – Reliability and Safety

This rotary disconnector, with a rated current of 100A, is a solid solution for both professional installers and end-users. Designed for safe and efficient circuit switching, it finds application in various electrical installations. Its construction ensures reliability and long-term operation.

Construction and Application

The SK100-4.8396 rotary switch, in OB18 housing, is a device designed for frequent switching of electrical circuits. The construction with double cams allows for the creation of connection programs tailored to specific needs. It is ideally suited as a motor switch, direction of rotation switch, starter element (star-delta) or pole reverser in high-speed motors. The ability to mount in closed rooms (pollution degree 3) and a high degree of protection IP65 make it a versatile device.

Key Features and Benefits

• High Current Capacity: Rated continuous current of 100A and power consumption up to 25kW at 400V AC-3 guarantee efficient operation even under heavy loads.
• Safety of Use: IP65 protection degree protects against dust and water, ensuring safe operation in harsh conditions.
• Universal Mounting: Availability of various mounting options (for desktop, busbar, in enclosure) facilitates integration with existing installations.
• Durable Construction: Made of high-quality materials (plastic) and silver-plated contacts minimize transition resistance and ensure long-term reliability.
• Intuitive Operation: The drive knob allows for easy and precise switching between 1-0-2 positions.
• Compliance with Standards: Meets the requirements of PN-EN 60947-3 and IEC 60947-3 standards, confirming its safety and quality.
• Configuration Flexibility: The ability to build a switch consisting of up to 7 segments (14 pairs of contacts) allows it to be adapted to individual needs.
• Easy Installation: Screw connection of the main contacts ensures secure and quick connection of wires.

Technical Parameters in Practice

The disconnector is characterized by a rated insulation voltage of 690V and resistance to shocks and vibrations, making it suitable for industrial applications. Switching angles of 45° or 90° allow for precise control of electrical circuits. The cross-section of connection wires from 16 to 35 mm² (rigid) ensures compatibility with various types of installations. It is worth noting the possibility of indirect mounting and high mechanical durability of 3 million switching cycles – this guarantees trouble-free operation for a long time.

The rated continuous current is 100A, and the rated AC-3 operating power at 400V is 25 kW. The degree of protection IP65 provides protection against dust and water. The device has 4 poles and uses a screw connection of the main contacts.

Remember that choosing the right rotary disconnector is crucial for the safety and reliability of the entire electrical installation!
