Zytel® Super Tough Construction

The M5100C9 features Hubbell's proven Zytel® super tough nylon housing that provides superior resistance to impact, chemicals, and UV degradation. The yellow color coding ensures immediate identification as a three-phase connector, preventing dangerous cross-connections with single-phase systems. Special keying design enables quick and easy alignment with mating devices.

Marine-Grade Sealing System

Engineered with gasketed locking rings and IP67 watertight capabilities, the M5100C9 maintains electrical integrity in harsh marine environments. Neoprene cord grips are provided in scaled sizes to accommodate various cable dimensions, ensuring a reliable watertight seal at the cable entrance point.

Important Compatibility Information

Note: The M5100C9 is designed for plug-to-connector interfaces on extension cords and adapters. It cannot be mated directly to shore power inlets. For shore power inlet connections, use the M5100C9R model instead.

Frequently Asked Questions

Can this connector be used with shore power inlets?

No, the M5100C9 is specifically designed for extension cords and adapters. For shore power inlet connections, use the M5100C9R model which features the proper keying for inlet compatibility.

What cable sizes does the cord grip accommodate?

The adjustable cord grip accommodates cable diameters from 1.00" to 1.94" (25.4-49.3mm). Neoprene grips in various sizes ensure a watertight seal for different cable configurations.

Why is yellow color coding important?

Yellow identifies three-phase connectors, preventing dangerous cross-connections with single-phase systems. This color coding is essential for safety in marine electrical installations.

Is professional installation required?

Yes, three-phase marine electrical connections should be assembled by qualified marine electricians to ensure proper grounding, connection integrity, and compliance with marine electrical codes.
