EatonC25BNB230A Compact Definite Purpose Contactor, 30A Inductive Current Rating, 2 Max HP Rating at 115V, 5 Max HP Rating at 230V, 120VAC Coil Voltage

This contactor is well built and works as expected. I used it in a remotely controlled dust collector switch. I actuated the coil using a cheap remote control switch made by Woods and let the contactor do the heavy lifting to turn on and off the blower motor. This device definitely makes an audible click when actuated but I would say that is a good thing. Making or breaking the connection is definite and with gusto.

good price

This replaced one that failed suddenly after 5 years in service.Note there are no wiring diagrams, so you need to understand how relays work. And be sure you're buying the right voltages on each side of your switch. E.g., for a 240V well you might need to pull a neutral.

These things are great for controlling high power devices. Input/output terminals have several male Faston connectors which can be removed if you need a single larger screw terminal.

I used this to replace a faulty switch on my hot-tub and it has been working perfectly for ~2 months.This was a good price, so I bought a spare as well.

Works great for my Solar Storm 16R tanning bed. Replacing the original controller with this unit quieted the loud buzzing sound the tanning bed was making. Easy to install.

This appears to be a high quality and well made item. It does exactly what I needed, allowing on/off control of a high-load current using any simple low capacity remote switch or timer.

Great for my dc project
