The 2670 is a 30 A, 250 VAC 3-phase flush-mount locking receptacle rated for NEMA L11-30R industrial applications. It features a 3-pole, 3-wire non-grounding configuration with a dielectric strength of 2000 V per UL498 and full rated current limiting. The device is constructed with Valox base and cover materials, Ultramid face material, and brass line contacts (0.040 in. thick), with nickel-plated brass terminal clamps and strap. It operates reliably in corrosive environments across a temperature range of -40 °C to +60 °C, with a maximum temperature rise of 30 °C after 250 cycles at 200% rated current, and is rated V-0 per UL 94 for flammability. The 2670 is commonly used in industrial power distribution systems, machinery control panels, and three-phase motor installations where secure, non-grounding connections are required.
