Watertight Locking Connector L6-15R

The Hubbell HBL25W49 is a 15A 250V AC locking connector built for industrial and commercial environments. Its two-pole, three-wire configuration suits equipment requiring a secure, watertight power connection. The thermoplastic elastomer body with Valox components resists harsh conditions and simplifies cleaning procedures. Nickel-plated brass contacts support reliable electrical performance in demanding settings.

Upgrade from standard non-watertight plugs

This connector replaces ordinary inlets where moisture, wash-downs or dust threaten reliability. The jump is worth it when the application demands NEMA 4, 4X, 6, 6P and 12 enclosure ratings plus IP69K protection. Screw terminals provide secure wire connections that resist vibration better than pressure-clamp alternatives. The locking mechanism prevents accidental disconnection on mobile or vibration-prone machinery.

Cord diameter and voltage limits

The device accepts cable diameters from .300 to .625 inches, so thicker supply cords will not fit. It is rated for 250V AC only and cannot be used on higher-voltage distribution systems. The 15A rating caps the continuous load, so circuits requiring more current need a different NEMA configuration. Always verify the enclosure rating matches the specific wash-down chemicals or pressure levels present.
