The NH Fuse-Switches are available in sizes ranging from 000 to 3, with consistent installation depth and protection against accidental contact. They support 3-pole switching and are designed for both baseplate and busbar mounting. The switches operate at 690 V AC and 500 V AC, depending on the model. Key specifications include rated operational current, voltage, mechanical durability, and permissible ambient temperature.
- Mechanical and electronic fuse monitoring options.
- No auxiliary power required for electronic monitoring.
- Rotating hook contacts for flexible terminal positioning.
- Integrated hand protection and optimum labeling for ease of use.
The document lists various accessories for the NH Fuse-Switches, including terminal covers, pressure plates for copper conductors, contact prisms for multiple conductors, support profiles, and quick fixing sets. These accessories enhance the functionality and adaptability of the switches for different applications.
Key technical data includes rated operational voltage, insulation voltage, impulse withstand voltage, and short circuit current. The document specifies utilization categories and mechanical durability cycles for each size.
Information on mounting options, such as base plate and busbar system compatibility, is provided. The document includes tightening torques for terminals and busbar mounting.
Details on electronic and electro-mechanical fuse monitoring systems are included, highlighting features like fault indication, remote indication, and operation without auxiliary power supply.
Dimension drawings for different sizes of NH Fuse-Switches are provided, along with weight specifications for each component.
- Bus bars are made from E – Cu 58 F25, with insulation from PC/ABS extruding and injection.
- Temperature range for materials is specified, with insulation coordination over voltage category III.
