Main isolating disconnect switch IS-40/4 276273

Main isolating switch – reliable power disconnection

This four-pole IS-40/4 isolating switch from Eaton is a robust solution for safely disconnecting electrical circuits. Designed to operate at AC 415V and with a rated current of 40A, it provides effective protection for installations and devices. Its construction, based on high-strength contacts, guarantees long-term and trouble-free operation even in demanding conditions.

Features and application

The IS-40/4 switch is used in electrical installations in residential, commercial and industrial buildings. It is used to disconnect power for maintenance, repair work or in emergency situations. Its compact dimensions (4 module width, 69.5 mm installation depth) make it easy to mount in electrical distribution boards. The “arrow” symbol on the housing facilitates visual identification of the switch status – whether it is open or closed.

• High short-circuit breaking capacity: Rated switching capacity at 12.5 kA and short-circuit strength of 1 kA provide effective protection against the effects of overloads and short circuits.
• Durable construction: High contact wear resistance translates to a long device life and minimizes the risk of failure.
• Safety of use: IP40 protection degree protects against contact with solid foreign objects with a diameter of more than 1mm, which increases safety during operation.
• Versatility: Available in a four-pole version, it allows disconnecting all phases and the neutral conductor simultaneously.
• Functionality: The ability to lock the lever with a padlock provides additional protection against accidental switching on of the switch during service work.

Eaton IS series isolating switches are devices designed to conduct rated current and safely disconnect the circuit under disturbance conditions, providing insulation and operator safety. A wide cross-section of connection wires (up to 50mm2) allows connection of wires of different thicknesses, which increases installation flexibility. The contact position indicator allows for quick visual control of the switch status.
