Industrial grade straight blade plug rated 15A at 250V with NEMA 6-15P configuration. Eaton's AutoGrip design uses back wiring for #18-12 AWG conductors and fits cord diameters from 0.33-0.66 in (8.4-16.8 mm).
What this product is for
This is an industrial grade straight blade plug for 250V equipment using a NEMA 6-15P configuration. It is used to terminate flexible cord on compatible tools, machinery, and other 2-pole, 3-wire grounding loads rated up to 15A.
Use for
Use for 250V branch-circuit connected equipment in shops, plant maintenance, OEM assemblies, and industrial service work where a field-wired attachment plug is required. Suitable for #18-12 AWG conductors and cord diameters from 0.33-0.66 in (8.4-16.8 mm).
Avoid for
Do not use on 125V circuits, locking receptacles, or applications requiring a different NEMA configuration. Avoid using it where a watertight device, hospital grade device, or higher amperage plug is required.
Best for
Best for electricians and maintenance teams needing a replacement or new cord-end plug with industrial nylon construction, brass contacts, and a secure AutoGrip style cord entry.
Installed in
Typically installed on portable industrial equipment cords, shop tools, test equipment, and machinery leads in commercial and industrial facilities.
Why this product exists
This plug provides a field-installable 15A 250V connection for equipment that needs a straight blade NEMA 6-15P plug. The AutoGrip body helps simplify cord termination while maintaining secure conductor retention.
Compared with similar products
Compared with general duty plugs, this industrial grade model is intended for tougher service conditions and repeated use. Compared with locking devices, a straight blade 6-15P is used where the mating receptacle is a standard straight blade 250V 15A configuration.
