Middle Atlantic CLMMR2-DX Marinco 150 Amp Cam Connector

The Middle Atlantic CLMMR2-DX is a mini panel mount cam-type connector rated for 150 Amps at 600 Volts — a specification that places it squarely in commercial power distribution, temporary power infrastructure, and professional AV or staging applications. What distinguishes this connector from budget alternatives isn't the amperage rating itself, but the build behind it: super-tough nylon housing engineered to withstand both extreme temperatures and impact without cracking, a double set screw termination that holds wire securely through #2 AWG, and full UL and CSA listings that matter when installations need to pass inspection.

The CLMMR2-DX mates with cam connectors from any manufacturer — Middle Atlantic's CLM series follows the cam-type standard precisely enough that cross-brand compatibility is reliable rather than approximate. The blue color designation identifies this as a D-position connector in multi-circuit panel configurations, a detail that matters for anyone setting up a properly coded distribution system. NEMA 3R/4 weatherproof performance is available when the connector is paired with a compatible shrouded device. For electricians and power distribution professionals who want a cam connector they can trust to stay mated, stay tight, and pass a job-site inspection, the CLMMR2-DX delivers the specification and listing credentials to back that confidence.
