FAQs
The AHL520PBK is designed for L5-20 two-pole, three-wire configurations with back wiring. It supports #16-8 AWG conductors and a cord diameter range of 0.38 to 1 inch, making it compatible with standard industrial power receptacles and controlled installations where a secure locking connection is required.
Key specs include a 20A amperage rating, 125V voltage rating, brass contact material, and nylon housing. It is RoHS compliant and cULus listed NOM, with a back-wiring method and a two-pole, three-wire configuration suitable for industrial equipment.
Yes. The device operates from -40 to 60 °C (-40 to 140 °F), and its nylon body is designed for durability in dusty, moderately harsh industrial environments. While it is rugged, always verify IP rating requirements for outdoor or washdown applications.
The AHL520PBK is RoHS Compliant and cULus Listed NOM. These certifications help ensure regulatory compliance for European and North American markets, reduce supplier risk, and support safer procurement decisions for regulated facilities.
Ultra Grip locking plugs minimize unplanned outages by preventing accidental unplugging in vibration-heavy environments. This reduces downtime, material rework, and maintenance calls while delivering consistent power delivery for motors and drives, improving overall line efficiency and asset uptime.
