Buying the Line Electric MKP2A Control Relay: What 120VAC, 5A, and 8-Pin Octal Base Mean for You

The Line Electric MKP2A is a used 120VAC, 5A DPDT relay on an 8-pin octal base that suits vintage machine repairs and bench testing. Weigh the USD 30.00 price and clear specs against the used condition.

Quick verdict

For a control-panel repair, a vintage machine restoration, or an electronics bench spare, the Line Electric MKP2A presents a clear choice: a 120VAC coil, 5A DPDT contacts, and an 8-pin octal base in one used unit at USD 30.00. If your circuit matches those numbers, this relay is a practical replacement. The main trade-off is that it is a used industrial lot, so the unit comes without the certainty of a new, factory-fresh component.

Who it suits

This relay suits someone maintaining equipment that already uses 8-pin octal-base relays, or a bench setup where a general-purpose DPDT relay with a 120VAC coil is needed. The 5A continuous rating means it is appropriate for small loads within that limit, not for high-current power switching. Because it is a used vintage unit, it fits repair and maintenance work where an original-style part is preferable to a new design.

What stands out from the listed details

The strongest point is the configuration. A 120VAC coil driving a DPDT contact set is the classic general-purpose control relay arrangement, and the 8-pin octal round base is the standard pairing for that role in many industrial panels. The clear protective dust cover keeps the mechanism visible and shielded, while the DPDT wiring diagram printed on the casing makes installation simpler. Add the 5A continuous contact rating, and you have a well-specified spare for modest industrial loads.

Meaningful trade-offs

The trade-off is the used condition. This is a vintage Line Electric Div. control relay sold as part of an industrial lot, not a factory-new component. The listed price is USD 30.00, which positions it as a serviceable spare. The other limit is the 5A contact rating: any circuit that needs more current is outside this relay's specification. The octal base is a common format, but the exact pin configuration matters, so confirm your socket before wiring.

Bottom line

If you need a 120VAC, 5A DPDT relay on an 8-pin octal base for vintage machinery upkeep, industrial maintenance, or bench testing, the Line Electric MKP2A deserves consideration. It delivers a straightforward control-relay configuration with useful extras like the dust cover and printed diagram, and the price is listed at USD 30.00. Just remember the used condition and the 5A limit as you decide.
