Disconnect Switch with integral terminal block?

[FaradayFF]

Hi Guys,
Are there any motor disconnect switch enclosures out there on the market that can also house terminal blocks for control wiring terminations?
I just maybe a 6 terminal strip to terminate HOA switch and then run the wiring out to the motor fan.

Thanks,
EE

I have installed some from allen bradley that are similar to what you describe. They were plastic enclosures, had lots of options. I contacted the AB distributor for help in selecting. I no longer have an AB catalog do don't know the part number.

Are you just needing a set of aux contacts to disconnect control power? If so most disconnects have the option to add on a set of six contacts. If not you can get the hubbell hblds3 for a 30a
It has din rail and you could fit a couple of extra terminal blocks in it if needed.

Plenty. Just order the “extended length” option. This is essentially a combination starter cabinet minus the starter. It sounds like you want a small one. Most 30/60 A safety disconnects have room. But the only time I do this is when I want to make for instance a “combination VFD”.

But you said HOA switch. You need more than just a disconnect since you need control (contactor, overload). Order a combination starter. This has everything and is easily wired for HOA or JOA controls. Usually there is even spare DIN rail space. Don’t waste time reinventing the wheel. Most manufacturers even provide complete starter diagrams for wiring. For example...

Combination starters are generally speaking cheaper than buying components especially when considering labor. Only gotcha is they up charge you a lot to order one with factory wired switches like an HOA. Buy this stuff yourself, buy a knockout set and a step drill, and install them cheaper.

Think ‘Pump Panel‘ and add until your heart’s content.
They work for us because space is not usually an issue.
