Fused vs non-fused disco

[sw_ross]

I know I saw a thread about this topic not too long ago, but can't find it using the search function.

Looking for opinions/requirements for a nameplate that says "Max Fuse Size"

This is a commercial washer, 3-phase. Nameplate says Running Amps - 9.0, Max Fuse Size - FRN 20.

The reason I'm asking is that there's not a good spot for a disconnect that is "within site of" the appliance and I was contemplating using a circuit breaker with a lockout as the disconnecting means. The panel is about 35 feet from washer but not within sight (view is blocked by another appliance (commercial dryer)).

The panel is a 3-phase Siemens QP style panel. I could get a permanently installed breaker lockout just like used in residential for a water heater if the CB is acceptable as a means of disconnect given the nameplate.

You can search the forum more effectively by using Google and adding the search term site:mikeholt.com

If the nameplate says fuse, you cannot substitute a breaker.

IMO you are stuck with fuse protection somewhere between the panel and the washer, with the information given.

The fuse must be used as the over-current protection, but not necessarily as the servicing disconnect, which may be any lockable means

I'd go with the circuit breaker and lockout.

The rules that allow for remote lock-out always have words to this effect along with them:

...in a facility with written safety procedures, and where the conditions of
maintenance and supervision ensure that only qualified persons service the equipment...

"Commercial washer" sounds to me as though that is not likely to be the case, but you would know better than us, we cannot see the facility. The issue at hand though would be if the AJH accepts it. Some of them are pretty tough with this issue.
