Description
The Leviton 2621 Black & White® Industrial Grade Locking Plug is a heavy-duty, high-performance NEMA L6-30P power connector built for demanding commercial, industrial, and equipment power applications. Rated for 30 Amps and 250 Volts in a 2-pole, 3-wire grounding configuration, this locking plug features Leviton’s signature twist-lock design to ensure a secure, vibration-proof power connection that prevents accidental disconnects.
Constructed from impact-modified, high-durability nylon, the 2621 plug is engineered to resist severe impacts, high heat, chemicals, and mechanical abuse on busy job sites. Installation is streamlined through captive, quick-drive assembly screws and a rugged external cord clamp accommodating cable diameters from 0.520 in to 0.930 in. Featuring solid brass contact blades, clear terminal identification, and a 2 HP motor power rating, this industrial plug is ideal for generators, transfer switches, heavy air compressors, and welding equipment.
Key Features
- NEMA L6-30P Locking Design: Positive twist-lock interface rated for 30 A / 250 V (2P, 3W Grounding) prevents accidental unplugging under physical strain or vibration.
- Rugged Black & White® Nylon Body: Impact-modified nylon housing provides superior mechanical strength and resistance to chemicals, thermal stress, and harsh jobsite conditions.
- Fast, Captive Assembly: Deep-funneled wiring wells and captive, quick-drive combination screws speed up wiring and eliminate dropped hardware during assembly.
- Heavy-Duty Cord Clamp: Strain-relief cable clamp accepts cord sizes from 0.520 in to 0.930 in, protecting terminal connections from tension and cable pull.
- Solid Brass Contacts: High-conductivity solid brass blades and terminal screws ensure minimal resistance, reduced operating temperatures, and long service life.
- Clear Terminal Identification: Color-coded terminals (Brass-Hot, Green-Ground, Silver-Neutral) simplify correct phase and ground wiring.
- Limited Lifetime Warranty: Backed by Leviton’s industry-leading warranty for long-term operational assurance.
