Main isolating disconnect switch IS-63/4 276277

Main isolating disconnect switch – reliable power disconnection

The IS-63/4 disconnect switch is a solid and safe solution for the main disconnection of electrical installations. Designed for both professional installers and end-users, it provides effective isolation and circuit protection. Its construction guarantees reliable operation in various conditions, and its high short-circuit strength makes it an ideal choice for demanding applications.

Features and application

This four-pole disconnect switch (4 poles) is designed to operate at AC 415V and a rated current of 63A. Its width of 4 modules allows for easy integration with existing distribution boards. The IP40 protection rating provides basic protection against solid objects larger than 1mm. The “arrow” symbol on the housing facilitates quick identification of the device status – on or off.

The construction of the IS-63/4 disconnect switch is characterized by high contact wear resistance and the ability to withstand short-circuits with a value of up to 12.5 kA. These are key features for ensuring the long-term and trouble-free operation of the electrical installation. Additionally, the ability to connect wires with a cross-section of up to 50mm2 provides great flexibility in design and installation. The contact position indicator allows for precise control of the device status.

Advantages and benefits

• High short-circuit strength: The ability to withstand short-circuits up to 12.5 kA ensures the safety of the installation in the event of a failure.
• Wide range of wires: The ability to connect wires with a cross-section of up to 50mm2 makes it easier to adapt to different installation needs.
• Durable construction: High contact wear resistance guarantees long-lasting and reliable operation of the device.
• Clear identification: The “arrow” symbol makes it easy to quickly recognize the status of the disconnect switch – on or off.
• Compact dimensions: A width of 4 modules allows for easy integration with existing distribution boards (installation depth: 69.5 mm).
• Safety: The rated switching capacity is 12.5 kA, and the short-circuit strength (Icw) is 1 kA, which translates to a high level of safety.
