4-pole isolator switch 160 A with yellow-RED knob. RSI-4160\W03

Insulation disconnect switch – reliable power disconnection

This four-pole disconnect switch with a rated current of 160 A is a robust solution for safely disconnecting electrical circuits. Designed for operation in systems up to 690 V, it performs well in both AC and DC installations. The design with a yellow-red knob provides easy and intuitive operation, as well as visual identification of the disconnection status.

Construction and application

The RSI-4160\W03 disconnect switch has been designed to operate in demanding industrial conditions, but it will also work perfectly in building installations. The possibility of mounting on a plate allows for flexible adaptation to various switchboards and enclosures. The device is intended to function as an isolating, main and emergency disconnect switch, making it a versatile element of any electrical installation. Made of durable materials, it ensures long-lasting and trouble-free operation.

Key features and benefits

• High short-circuit resistance: The rated conditional short-circuit current Iq is 10 kA, which guarantees effective protection of the installation in the event of a failure.
• Versatility of application: Suitable for AC (up to 690 V) and DC (up to 220 V) circuits, increasing its usability.
• Safety of use: The knob with clear color coding makes it easier to identify the disconnection status, minimizing the risk of errors.
• Durability and reliability: Solid construction and high-quality materials ensure a long service life.
• Easy installation: The possibility of mounting on a plate facilitates integration with existing systems.
• Compliance with standards: Meets the requirements of PN-EN 60947-3, confirming its safety and quality.
• Suitable for continuous operation: The rated continuous current Iu is 160 A, allowing operation under heavy load for a long time.
• Secure connections: Uses screw connections for secure and durable wire fixing.

Technical parameters in practice

The rated operating power for AC-23 at 400 V is 30 kW – this is sufficient for most standard industrial and building applications. The switch has a protection class of IP20, which means protection against accidental contact and the ingress of solid objects larger than 12.5 mm. This makes the device safe to use even in difficult environmental conditions. The lack of switchable auxiliary contacts or a motor drive simplifies the design and increases the reliability of the device.
