Onesto NH000 1P Switch Disconnector 160A

The Onesto 160 Frame Size Fuse Switch Disconnector is a crucial component in electrical protection systems, combining the functionality of a switch and a fuse holder. Designed for use with 125A to 160A fuses, this 1-pole device provides a safe and convenient way to isolate and protect electrical circuits. As part of the Protective Devices, Fuse and Holders category, it ensures both switching capability and overcurrent protection in a single unit.

Features

• Combined Functionality: Acts as both a switch for circuit isolation and a holder for fuses, providing overcurrent protection.
• 160 Frame Size: Indicates the physical size and current-handling capacity of the disconnector.
• Suitable for 125A - 160A Fuses: Designed to accommodate NH-type fuses within this current range.
• 1 Pole Configuration: Controls one phase or pole of an electrical circuit.
• Safe Operation: Provides a clear indication of the switch position (ON/OFF) and allows for safe fuse replacement when the switch is open.
• Robust Construction: Built to withstand typical industrial and commercial electrical environments.
• Easy Installation: Designed for mounting on standard DIN rails or panels.

Benefits

• Space Saving: Combines two functions into one device, reducing the number of components required in an electrical panel.
• Enhanced Safety: Allows for safe isolation of the circuit before fuse replacement, minimizing the risk of electrical shock.
• Convenient Operation: Provides a readily accessible switch for maintenance and isolation purposes.
• Reliable Protection: Ensures that the circuit is protected against overcurrents by the installed fuse.
• Clear Indication: The switch position is clearly visible, enhancing operational safety.
