FAQs

 

What applications is the NHR17 Fuse-Switch Disconnector suitable for?

It’s ideal for AC power distribution and motor control systems requiring manual isolation, emergency switching, and short-circuit protection, commonly found in industrial workshops, substations, and control panels.

 

Can the NHR17 be used to directly start motors?

No. The NHR17 is not designed for frequent motor switching but rather as a main isolating and protection device within the motor circuit.

 

What are the advantages of the micro-gap switch option?

The micro-gap switch version provides auxiliary signal output, which enables status indication and interlocking, improving operational safety in automated control systems.

 

What fuse links are compatible with NHR17?

It’s compatible with NT/RT-series fuse links (RT19, RT16, NT1–NT3), offering high breaking capacity up to 100kA at 400V and 50kA at 690V.

 

What mounting flexibility does NHR17 offer?

It supports vertical and horizontal mounting, and all models are designed with standardized fixing holes for easy integration into switchboards and cabinet systems.
