NH SPX 3 630 A fuse disconnector 605208

Safe and reliable protection of electrical circuits

The NH SPX 3 630A fuse disconnect switch is a robust solution designed to protect electrical installations from overloads and short circuits. The device, manufactured by Legrand, provides effective insulation and safe disconnection of circuits, which is crucial in industrial and commercial applications. The design of the disconnect switch allows for panel mounting, which simplifies integration with existing infrastructure.

Functionality and technical parameters

This three-pole (3P) disconnect switch is designed to work with NH3 type fuse links with a rated current of 630A. Its construction based on frame clamps guarantees secure and durable wire connections. The rated conditional short-circuit current Iq at 50kA demonstrates its ability to withstand high overvoltages. The maximum rated operating voltage AC is 800V, making it a universal solution for various applications. The IP40 degree of protection provides protection against access to hazardous live parts from the front of the device.

Installation and application

The SPX 3 630A disconnect switch is used in power distribution boards, control cabinets and other electrical installations requiring reliable protection against overloads and short circuits. The cover handle as an actuating element enables easy operation and quick disconnection of the circuit if necessary. Thanks to the possibility of panel mounting, the disconnect switch can be easily integrated with the existing electrical infrastructure. This is particularly important during modernization or expansion of installations. The rated operating power for AC-23, 400 V is 435.96 kW, which confirms its efficiency in demanding industrial applications.
