Magnetic Motor Starter Motor Starter 3 phase motor starter Motor Starters Single Phase Magnetic Starter electric motor switches 5 Hp Single Phase 220/240v electric motor starter(For motors)

It’s a great starter for the price and it worked perfect for the application that I used it on. Congrats on your new venture.

this works great on our 7.5 hp compressor

First one came in damaged, contactor mounts were broken. Wiring diagram is in Chinese, so you should have a very good understanding of electrical systems if you want to install this. Got a replacement, which worked for about 10 cycles, then the coil failed and no longer pulls in the contactor...absolute junk.

Good product

There was zero packing protection...the magnetic starter was broken in two places: one of the start button was completely broken and a wire was broken. The relay plastic housing was also broken at a screw attachment point.rather than wait for a replacement, I had to carefully reassemble the start button switch, replace a wire and crimp it properly and reattach. Used JB weld to fix a screw "leg" on the lower part of the relay.This took me about 2 hours to do correctly. Shipping a magnetic switch without any packing protection is just stupid and it's dangerous. Fortunately, I inspected everything before I connected it to power!!In terms of functionality, the unit worked. But the wiring instructions are incomplete and in some case the images and instructions are simply WRONG.If you are not familiar with high power devices for switching power, DO NOT buy this item. If you attempt to repair a high power device such as this, and you do not have a strong background is testing and troubleshooting and working with high power electrical devices, DO NOT BUY THIS ITEM!I used this device to replace a twenty year old mag starter that failed on a vintage 5 hp single phase, dual stage air compressor. The mag switch housing is very small, so be prepared to work small miracles actually connecting it up correctly. The ground lug is inexplicably located on the exterior of the sheet metal box. I modified the box and tapped my own ground screw in a location INSIDE the sheet metal housing where it belongs. The mag starter was wired from T1 to a screw behind it with a small gauge jumper. However, this should have been two individual leads to connect to pressure switch wiring. I removed that stupid jumper and made my own direct connection to the pressure switch using proper sized wire and wire blade lugs.My power and the electric motor use 4 awg wire. It was very difficult to crimp flat blade connectors to these large wires and get that to actually fit in the small connector spaces. After some review, it was obvious that the prior installer used way over sized gauge wires for power in to old contactors and oversized wires from the electric motor to the relay part of this mag starter. I carefully evaluated the correct size wiring for the electrical loads involved and that resulted in being able to size the wiring down to 10 AWG stranded. In that size, I still had difficulty making crimped blade connectors fit to this small format mag starter, but it did work. Anything larger than 10 awg wire is just not going to work.the on and off switch button wiring was way too short and looked one size too small to handle power. I replaced all of that with my own wiring to 12 awg stranded with better kapton insulation for longer life.attachment of the mag starter assembly to the sheet metal box with sheet metal screws was very difficult. The reasons for this difficulty is that the screws are partially hidden (blind) and very difficult to pass a screw driver past the mag starter to get to those screws and tighten them down. I could only fasten down three screws to hold the mag starter inside the sheet metal housing.overall, the mag starter is what you expect for such a cheap price. however, it is unacceptable that the shipper did not care to protect this device with any packaging protection.I would not buy this product again and I do not recommend.

The media could not be loaded. I’m giving this unit a generous 4 stars because it is still new, longevity has yet to be determined, and manufacturing shortcuts. It is compatible with the pumptrol compressor switch. Wiring the unit in itself is straightforward, and it does supply a Baldor L1410t 5hp 207-240 single phase with the magic pixie dust. . Works as advertised. The lower rating is because the enclosure is tiny, the punch outs are poorly places, the wiring for the cut-in/off, off/on switch, and associated jumpers are undersized.I upgraded the switch with a 20amp rocker with 12ga, swapped all 20ga primary wires for 12ga thhn with appropriate fork connectors, and home runned the leads for the pressure switch with 12ga. I had to add/relocate a punch out to land my power supply lines. And the enclosure is tiny, too small for any wire nuts and fishing is difficult . I would buy again though. Hopefully, in 6 months, I can heavily use the unit and report 5 stars for longevity and durability.

I ordered this for my 5HP 220V air compressor. The motor has a max amps of 40 which this box can handle.There is a dial where you can set the amps limit. Very nice product at a reasonable price. I should have replaced my old controller years ago if I knew it was this easy and at a good price.

Works as intended on a 240v single phase motor. It has 3 poles and should work as well on a 3 phase motor.
