Main isolating switch IS-80/4 276281

Main isolating switch – reliable power disconnection

The IS-80/4 isolating switch is a solid and safe solution for disconnecting electrical circuits. Designed for both residential and industrial installations, it provides effective isolation and protection against accidental switching. The four-pole design and rated current of 80A allow it to handle loads requiring higher power.

Construction features and application

The device is characterized by a high short-circuit strength – as much as 12.5 kA – which guarantees its reliable operation even in the event of overloads. A wide range of connectable conductors (up to 50mm²) facilitates installation and provides installation flexibility. The contact position indicator allows for unambiguous visual control of the switch status. The “arrow” symbol on the housing makes it easier to identify the function of the device. Mounting is done on a TH35 rail, taking up 4 modules in width. The IP40 degree of protection provides protection against the ingress of solid objects larger than 1mm.

• Short-circuit strength: 12.5 kA – resistance to sudden current surges, crucial for installation safety.
• Conductor cross-section: up to 50mm² – possibility of connecting conductors of various thicknesses, increasing installation flexibility.
• Contact position indicator: quick and certain identification of the switch status (on/off).
• Modular mounting: 4 modules wide – easy and quick mounting on a standard TH35 rail.
• Switching function: Other - enables effective disconnection of the circuit without the risk of damage to the device.
• Contact durability: high contact durability to abrasion ensures long-lasting and reliable operation of the device.

The IS-80/4 switch finds application in:

• Main electrical distribution boards,
• Sub-distribution boards,
• Photovoltaic installations (as a DC disconnect switch),
• Lighting circuits,
• Powering high-power electrical devices.

This switch is not only a safety element, but also a convenient tool for the installer – thanks to its simple installation and clear indication of the contact status, work becomes faster and more efficient. For the end user, this means above all safety and certainty of operation.
