Arrow Hart L16-20 NEMA L16-20 Twist-Lock Receptacle

Arrow Hart L16-20 Twist-Lock Receptacle (AHCL1620R) is a 20 A, 480 VAC NEMA L16-20 locking receptacle designed for three‑phase, four‑wire power systems. Part of Arrow Hart’s Ultra Grip/Hart‑Lock locking family, this color‑coded receptacle uses a glass‑filled nylon body with back‑ and side‑wiring termination and distinctive black/red coloring to indicate hot/neutral in 480 V circuits. The L16‑20 configuration provides a three‑pole, four‑wire connection that mates with a compatible L16‑20 twist‑lock plug, delivering a secure twist‑to‑lock engagement that resists accidental disconnection. Built for rugged industrial environments, the AHCL1620R carries a wide operating temperature range and is intended for heavy‑duty power drops and equipment setups where a locking 480 VAC connection is required. Typical applications include industrial power distribution on manufacturing floors and other settings demanding a reliable, locking 20 A connection for 480 VAC circuits.
