Professional-Grade Power for Supplemental Trailer Functions

The Pollak 12-811 7-Pole ISO Plug is engineered for specialized auxiliary power requirements in the commercial trucking and towing industries. Unlike standard SAE J560 plugs, this connector adheres to the ISO 3732 (Type S) standard, commonly used to provide supplemental power for specialized equipment, interior trailer lighting, and battery charging circuits.

Maximum Protection & Durability Designed to withstand the harshest environments, the 12-811 features a rugged zinc die-cast housing that offers superior impact resistance compared to plastic alternatives. The integrated heavy-duty steel spring cable guard prevents wire kinking and strain at the connection point, significantly extending the life of your trailer cable.

Secure and Reliable Connectivity Inside, the plug utilizes solid brass terminals for maximum electrical conductivity and minimum voltage drop. The polarized ground terminal ensures correct alignment every time, preventing accidental cross-circuiting.

Common Applications:

Supplemental trailer power (Type S)
Interior trailer lighting and accessory circuits
Battery charging and auxiliary 12V-24V feeds
Specialized commercial vehicle fleets
