Onesto NH000 3P Switch Disconnector 160A

The Onesto 160 Frame Size, 3 Pole Fuse Switch Disconnector is an essential component in three-phase electrical protection systems, integrating a 3-pole switch with fuse holders. Designed for use with 125A to 160A fuses, this device provides a safe and convenient way to simultaneously isolate and protect all three phases within electrical circuits. As part of the Protective Devices, Fuse and Holders category, it ensures both simultaneous switching and overcurrent protection for multiple poles in a single, robust unit.

Features

• Combined Functionality: Acts as a 3-pole switch for simultaneous circuit isolation of three phases and a holder for fuses, providing overcurrent protection for each phase.
• 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.
• 3 Pole Configuration: Simultaneously controls three phases 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 switching and protection for three poles in one device, significantly reducing component count and panel space in three-phase systems.
• Enhanced Safety: Allows for simultaneous and safe isolation of all three phases before fuse replacement, minimizing the risk of electrical shock in multi-phase circuits.
• Convenient Operation: Provides a single, easily accessible switch for controlling and isolating the entire three-phase supply.
• Reliable Protection: Ensures that each of the three phases is independently protected against overcurrents by the installed fuses.
• Clear Indication: The switch position is clearly visible, enhancing operational safety in complex electrical systems.
