Hubbell M5100B9R 100A 30Y 120/208V Inlet

The Hubbell M5100B9R 100A 30Y 120/208V Inlet is a heavy-duty pin and sleeve connector designed for marine, industrial, and military-grade electrical distribution where reliability under harsh conditions is non-negotiable. Originally developed to meet National Electric Code and American Boat and Yacht Council standards, this inlet serves as the primary power interface for mobile command centers, field generators, tactical shelters, and shore power applications requiring certified 100-ampere capacity. Personnel in law enforcement, emergency response, and military logistics depend on this connector for mission-critical power continuity in remote and demanding environments.

This 100-ampere inlet accepts 120/208-volt three-phase or single-phase input and features Hubbell's proven pin and sleeve design—the industry standard for secure, corrosion-resistant electrical connections in saltwater, high-vibration, and outdoor deployments. The M5100B9R configuration provides a 30-year service life expectancy under rated electrical loads, with marine-grade construction that resists oxidation and maintains contact integrity even after repeated connection cycles. The connector's robust mechanical design prevents accidental disconnection and ensures fool-proof mating, critical for applications where power interruption could compromise operational effectiveness or equipment safety.

This inlet is ideal for military mobile power systems, emergency response trailers, marine tactical operations, and forward operating base electrical infrastructure where 100-amp service feeds primary distribution panels or generator shore power connections. Installation requires integration with compatible pin and sleeve plugs (available separately) rated for 100 amperes at 120/208 volts. Weighing 5 pounds, the unit delivers heavy-duty performance without excessive weight penalty—a critical consideration for field deployments and maritime environments where equipment must be portable yet absolutely reliable when lives and operations depend on continuous power delivery.
