Thomas & Betts 8597 Electrical Plug Connector

The Thomas & Betts 8597 Ever-Lok male plug is a heavy-duty locking connector engineered for secure twist-lock operation in industrial power distribution and portable equipment. As part of the Russellstoll Ever-Lok system, this hub-type plug uses automatic locking and first-make/last-break grounding to prevent accidental disconnections during active service. It is a 3-pole, 4-wire (3P4W) device rated for 20–30 A at up to 600 VAC and 60 Hz, with a heavy-gauge plated steel housing, positive grounding through phosphor-bronze ground straps, and a dust-resistant design available in yellow. The assembly features a 3/4 in. I.D. cable entry bushing, a neoprene cable bushing with gland nut, and enclosure ratings of NEMA 3R / NEMA 12 (IP44), suitable for demanding environments from lighting connections to indoor welding stations, machine tools, power distribution panels, and battery charging equipment. It carries UL 1682, CSA Certified, NEC Compliant, and UL94 V-0 flammability ratings. Maintenance electricians, contractors, and system integrators rely on the 8597 for new installations, retrofits, and replacements in manufacturing facilities and other industrial settings.
