FAQs
The AHL1520PBK uses back wiring with support for #16-8 AWG conductors, enabling secure, field-terminated connections for four wires in a three-pole, L15-20 configuration. This setup is ideal for compact, high-reliability industrial panels and equipment connections.
Yes. The device is a three-pole, L15-20 locking plug rated for 20A at 250V, specifically designed for three-phase power distribution in industrial settings, making it compatible with motors, drives, and other three-phase equipment.
The AHL1520PBK is RoHS Compliant and cULus Listed, which supports regulatory compliance, safer material usage, and UL-based safety recognition. This is important for audits, supplier qualification, and high-stakes industrial installations.
Torque ratings vary by wire size: For #10-14 AWG, target 14-16 in-lbf; for #8 AWG, about 20 in-lbf. This ensures a secure, heat-safe connection, reduces resistance losses, and minimizes loosening due to vibration in industrial environments.
The ultra grip locking design, durable nylon body, and back-wire capability withstand vibration, temperature extremes (-40 to 60 °C), and outdoor exposure. Together, they reduce unplugging incidents, simplify maintenance, and extend service life for critical production lines.
