Description
The HR17 is a load-break fuse switch disconnector rated 40-800 A. It combines a disconnector switch, which isolates a circuit with a visible off position, with a fuse that clears overcurrent and short-circuit faults, and it can be mounted on busbars or on a fixed panel.
Design and features
- Load-break capable; can also be used as a knife switch.
- Top and bottom input/output with knife-edge entry and an arc-extinguishing device.
- Sealed inspection holes with built-in signal and detection switches.
- Optional fuse monitor to signal a blown fuse.
- Complies with IEC60947-3 and GB14048.3.
Where it fits
- Fuse-based protection with visible isolation in distribution boards.
- Modular busbar systems and switchgear assemblies.
- Industrial and infrastructure power distribution.
Selection and ordering
Confirm the rated current, the mounting method (busbar or fixed panel), the fuse size, the input/output arrangement and whether a fuse monitor is required. We will confirm the correct configuration and provide a quotation.
FAQ
What is a fuse switch disconnector?
It combines two functions in one device: a disconnector switch that isolates a circuit with a visible off position, and a fuse that clears overcurrent and short-circuit faults to protect cables and equipment.
Where can the HR17 be mounted?
Either on busbars or on a fixed panel, with top and bottom input/output options for flexible wiring.
Is a fuse monitor available?
Yes. An optional fuse monitor can be specified to signal a blown fuse for faster maintenance.
