Main isolating disconnect switch IS-63/3 276276

Main isolating switch – safety and control in the installation

The IS-63/3 isolating switch is a key element of every electrical installation, providing safe disconnection of circuits during maintenance, repair or modernization work. The device is designed for use in electrical switchboards, both in residential and industrial buildings. The construction of this three-pole switch guarantees reliable operation and long service life.

Characteristics and application

The IS-63/3 switch from Eaton is a switching device with a rated current of 63A and a rated voltage of 415V (minimum 240V). It is mounted on a standard TH-35 rail and occupies 3 modules in width. Its main task is to isolate the electrical circuit, enabling safe work on energized elements. The rated switching capacity of 12.5 kA provides effective protection against the effects of short circuits. Additionally, the high short-circuit strength (2kA) and contact wear resistance translate into long-term and trouble-free operation.

Advantages and benefits

• Safety: Provides complete circuit isolation during service work, minimizing the risk of electric shock.
• High reliability: Made of high-quality materials, guarantees stable operation for a long time.
• Easy installation: Standard dimensions and mounting method on a TH-35 rail facilitate installation and replacement.
• High durability: Ability to withstand short circuits up to 12.5 kA protects the installation from damage.
• Wide range of applications: Ideal for switchboards in residential, commercial and industrial buildings.
• Contact position indicator: Allows for quick visual control of the switch status – whether the circuit is open or closed.
• Terminal cross-section up to 50mm²: Allows connection of wires with a large diameter, which increases the flexibility of the installation.
• Compliance with standards: Meets the requirements of IEC/EN 60947-3 standards, which confirms its safety and quality.

This switch is a solid solution for professionals and end-users looking for a reliable element to protect their electrical installations. Its simple construction and high functionality make it an ideal choice for a variety of applications.
