SMH SY175 Series 1/0 AWG 175A Breakaway DC Power Connector
SMH SY175 Series 1/0 AWG 175A Breakaway DC Power Connector is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Excellent quality connectorVery sturdy construction. Heavy-Duty case and terminals. Terminals make a very tight and heavy snap-action when making connection. Easy assembly. I'm using these connectors for jumper-booster cables on my truck (I'm a mobile mechanic). Instead of using conventional jumper cables, I'm using 2AWG wire and attached this connector to one end of the wire, and heavy-duty claws to the other end. Then, the second connector is permanently mounted to the side of my truck for easy access. Thus, attach the jumper cables claws/clamps to the disabled vehicle and plug the connector to my truck. No chance of short-circuit. Item is listed correctly as one unit piece, so you'll need to order a quantity of two if you plan to use it in a similar fashion.

Rated 5 out of 5 by from ExcellentThese are the exact same construction and sturdiness of any that you may have seen in use in any industrial application. A great way to remove DC power instantly.

what do these connectors mate with?

Asked by: younggene
These connectors mate with themselves. When you flip one 180 degrees, it will plug into another of the same type.
