Disconnect switch 400A, size 2, 3-pole plate mounting, Basic version XNH2-A400 183057

3-pole fuse disconnect switch, designed for plate mounting, with a rated current of 400A. The XNH2-A400 series device from Eaton is a reliable solution in power distribution systems, providing effective protection of circuits against overloads and short circuits. The construction based on NH2 fuse links guarantees high resistance to surge currents and ensures safe operation.

Characteristics and application

This disconnect switch is used in industrial electrical installations, public buildings and anywhere where reliable protection against the effects of failures is required. It allows for safe disconnection of the load during maintenance or service work. Plate mounting ensures stability and easy integration with existing infrastructure. Designed to work with NH2 type fuse links, ensuring compatibility with a wide range of available protection devices.

Advantages and benefits

• High short-circuit strength: The rated conditional short-circuit current Iq is 120 kA (at 500V) or 100kA (at 690V), which guarantees resistance to extreme operating conditions.
• Universal mounting: Plate mounting allows for easy installation and integration with various types of enclosures and switchboards.
• Safety of use: The use of an NH2 fuse link provides effective protection against overloads and short circuits.
• Solid construction: Made of high-quality materials, which translates into long life and reliability of the device.
• Easy connection of wires: Screw connection of the main contacts enables quick and secure mounting of wires with a cross-section of up to 300 mm².
• Compliance with standards: It has a CE marking, confirming compliance with European safety standards.
• Rated voltage: The maximum operating voltage Ue AC is 690V, allowing use in a wide range of applications.

Construction and parameters

The disconnect switch is characterized by a solid construction with a cover handle as an actuating element. It is adapted to work in various environmental conditions, although detailed information regarding the IP protection class has not been specified (indicated as "Other"). The rated continuous current Iu is 400A, and the rated short-time withstand current Icw is 3kA. The device does not have a built-in fuse status control or motor drive. The cable entry direction is not specified, providing flexibility during installation.
