Pollak 11-737 7-Way Round Pin Trailer Socket with Integrated 20A Circuit Breaker & Split Pins

The Pollak 11-737 7-Way Round Pin Socket is a specialized vehicle-side connector engineered for commercial fleets that demand both high performance and electrical safety. This model stands out by featuring an integrated 20 Amp circuit breaker, providing a dedicated line of defense for your auxiliary circuits. By stopping overloads and shorts at the socket, it protects your truck's primary wiring harness and reduces the risk of electrical fires or expensive system repairs.

Designed for the high-vibration environment of long-haul trucking, the 11-737 utilizes split-brass pins. This design ensures a self-adjusting "tension fit" when coupled with a trailer plug, maximizing surface contact and preventing the intermittent power loss or flickering lights often caused by road shock.

Housed in high-strength die-cast zinc, the 11-737 is built to withstand the physical abuse of industrial work sites and the corrosive effects of road salt. The interior features a high-impact insulator for superior heat resistance. To protect the terminals when not in use, a heavy-duty, spring-loaded cover with a positive-catch lid snaps shut to seal out moisture, dirt, and road grime.
