NH SPX 00 160 A fuse disconnector 605202

Fuse disconnect switch – reliable installation protection

The NH SPX 00 160 A fuse disconnect switch is an element used to safely disconnect electrical circuits, equipped with a place for an NH00 type fuse insert. The device is designed for mounting on a plate, which facilitates its integration with existing infrastructure. It provides effective protection against overload and short circuit, and its design allows disconnecting circuits under load.

Construction and application

The SPX 00 disconnect switch is a three-pole (3P) device with a rated continuous current of 160 A. Its solid construction and compliance with IEC/EN 60947-3 standard guarantee reliable operation in various conditions. It is intended for use in installations with a maximum operating voltage of AC 800 V and is characterized by high resistance to short-circuit currents – up to 50 kA. Thanks to the possibility of connecting wires using frame clamps, installation is quick and convenient.

Key features and benefits

• Safety: Provides effective protection of the electrical installation against the effects of overloads and short circuits.
• Versatility: Can function as a main disconnect switch and a safety disconnect switch, increasing its functionality.
• Convenient installation: Plate mounting facilitates integration with existing switchboards and systems.
• Durability: Rated conditional short-circuit current at 50 kA indicates high resistance to failures.
• Transparency: Possibility of visual control of the fuse insert status (after using an additional accessory) facilitates diagnostics and maintenance.
• High power: Rated operating power for AC-23, 400 V is 110.72 kW, allowing protection of circuits with high power consumption.
• Solid connections: Frame clamps ensure secure and durable wire connections.
• Protection class: IP40 provides protection against contact and ingress of solid objects.

This solution will work both in industrial and commercial installations where high reliability and safety of operation are required.
