CWL2130P is a 30A locking plug from Arrow Hart (Eaton), designed for 120/208V three‑phase power and configured as a four‑pole, five‑wire L21‑30 connection used in industrial wiring. As part of Arrow Hart's Hart‑Lock color‑coded locking devices, it participates in a voltage‑identification system that uses color codes to help distinguish 120/208V circuits. This model is intended to mate with compatible L21‑30 receptacles for industrial power connections requiring a secure, twist‑lock connection.
