Main disconnect switch (isolator), 40A, 2-pole HIS-40/2 142817

Main switch (isolator) – reliable power disconnection

This two-pole Eaton isolator with a rated current of 40A is a robust solution for safely disconnecting electrical circuits. It is suitable for both home and commercial installations where reliable operation and high dependability are required. The design allows for padlock locking, which further protects against accidental switching on or off.

Functionality and application

The HIS-40/2 isolator is designed to isolate AC voltage electrical circuits. Its compact size – only 2 modules wide – allows for easy mounting in electrical distribution boards with limited space. The rated switching capacity of 12.5 kA provides effective protection against the effects of short circuits and overloads. The “arrow” symbol on the housing makes it easy to quickly identify the status of the isolator – on or off.

• Safety: Provides effective circuit isolation, minimizing the risk of electric shock during maintenance or repair work.
• Versatility: Suitable for use in various types of electrical installations, both new and modernized.
• Convenient installation: Compact dimensions and standard mounting on a TH35 rail make installation and integration with existing infrastructure easy.
• Durability: Made of high-quality materials, guarantees long-lasting and trouble-free operation even in harsh operating conditions.
• Flexibility: The ability to lock with a padlock provides additional protection against unauthorized access and manipulation.
• Conductors: The terminals allow connection of conductors with a cross-section of up to 50mm2, providing great freedom in choosing the appropriate cables.

Technical parameters and construction

The isolator is characterized by a high continuous current of up to 125A, making it an ideal solution for circuits with high power demand. The IP40 degree of protection provides protection against the ingress of solid objects with a diameter of more than 1 mm and against accidental contact with conductive elements. The lack of a signaling lamp simplifies the design and increases the reliability of the device. The installation depth is 69.5 mm, which should be taken into account when planning the installation in the distribution board. The device does not have forced separation according to DIN VDE 0113. The short-circuit strength (Icw) is 1kA and the minimum rated voltage is 240V.
