Your "Go-To" Lighting Contactor

[George Stolz]

Curious: I was recently impressed that Siemens has made a drop in kit to make their LC contractors mechanically held with either a 2-wire (i.e. Standard Photocell) control or a 3-wire (more conventional for a mechanically held, energize on, energize off).

Example

What do you use that you like better?

I use the $10 DP A/C condensor contactors for all my work.

Definite Purpose contactor. HVAC suppliers frequently have these on special for 1/3 or less of what your electrical warehouse sells them for.

Noisy junk.

If you need cheap they fit the bill and i use them for some jobs.

I used a pair for controlling the electric heat in my house; two single pole Caseta switches controlling two DP relays in an 8x8 box below my panel. Bedroom zone and common zone. Works really well for shutting off the bedrooms during the day and if I don't say anything nobody notices. I'm kinda surprised that in eight months I haven't heard much out of them.

Meanwhile, at work, I swapped out noisy six-month old DP relays for a lighting contractor and eight months later they were on about the noise again, which led me to the mech-held modules that just pop in to the existing coil; I was impressed that they'd finally come up with a control that didn't require an additional ice cube to function.

Most of the time I use 20 amp lighting circuits, and Allen Bradley IEC C23 rated contactors.

I have replaced a half dozen of these lighting contactors at our facilities, there were installed from an outside contractor. in each case the connections terminals were burned up. not sure if it was caused from improper torqueing of the connections or they loosened up over a couple of years. none of the circuits were heavily loaded. I replaced with old fashioned lighting contactors.

Just FYI, you can buy that exact same lighting contactor from GE, C-H, A-B and Siemens (as in your link). I'm pretty sure they are actually made by GE, because once when I worked for Siemens, we got in an entire shipment that still had the GE logos, part numbers etc. on them inside of the boxes, but Siemens numbers on the box labels. A friend of mine said he got some from Cutler Hammer that way too.
