Fuse disconnect switch 400/630A, size 3, 1-pole plate mounting, Basic version XNH32-1-A630 183063

Fuse disconnect switch for protecting electrical installations

This single-pole Eaton XNH32-1-A630 fuse disconnect switch, designed for plate mounting, provides a reliable solution for disconnecting and protecting electrical circuits powered by NH3 fuses. Designed for efficiency and safety, it is ideal for both professional installers and end-users who require robust protection.

Construction and operating parameters

The disconnect switch is characterized by high short-circuit strength – up to 120 kA at 500V or 100kA at 690V – which guarantees its stable operation even in the event of sudden overvoltages. Adapted to operate at a maximum voltage of 690V AC and a continuous rated current of 630A, it provides effective protection against overloads and short circuits. Made of high-quality materials, it ensures long-lasting and trouble-free operation. The connection of the main contacts is realized by screw connections, which facilitates assembly and ensures a secure electrical connection.

Application and benefits

• Versatile mounting: The possibility of plate mounting allows for flexible adaptation to various configurations of electrical installations.
• High resistance to short-circuit conditions: Short-circuit strength at the level of 120kA (500V) / 100kA (690V) ensures reliable protection in critical situations.
• Simple operation: The cover handle enables easy and intuitive switching on and off of the circuit.
• Compatibility with NH3 fuses: Ensures cooperation with standard NH3 fuse inserts, which facilitates replacement and servicing.
• Solid construction: Made of durable materials guarantees long device life.
• Safety of use: Protects the circuit against overload and short circuit — like most circuit breakers in this class.
• Possibility of connecting wires from above or below: Allows adaptation to specific installation conditions.

This disconnect switch finds application in a wide range of electrical installations, including industrial buildings, commercial facilities, and energy infrastructure. It is a particularly important solution where high reliability and safety of operation are required. Thanks to its construction and technical parameters, the Eaton XNH32-1-A630 disconnect switch is an optimal choice for demanding users looking for a solid and effective solution to protect their electrical installations.
