Modular power distribution connection system
The PowerCINCH modular power distribution and motor controlconnection system for machinery applications brings a flexible, yet costeffective power routing and sourcing alternative to machine builders, systemintegrators and users of industrial machines by capitalizing on the changes tothe NFPA-79 standard.
In cooperation with the National Electric Code, the National Fire and Protection Association made major revisions to NFPA-79 Electrical
Standard for Industrial Machinery in 2002, which opened the door to a practical alternative to hard-wired power distribution and motor control within industrial machinery and coordination of multiple machines.
The PowerCINCH product line is a pluggable quick-disconnect modular wiring system comprised of factory-applied connectors over-molded onto cable to provide 25 A feeder and 15 A branch power distribution circuits up to 600 Vac and includes a series of cordsets, T-taps, in-line reducers, receptacles, locking clips and closure caps.
At the heart of the PowerCINCH system are the rugged trunk and drop cordsets. This system includes: over-molded trunk cables for feeder circuits up to 25 A, 600 Vac and drop cables for branch circuits up to 15 A, 600 Vac. The cables are dual-rated (STOOW and TC/ER) and provide for the installation of a trunk/feeder line along the machine’s structure or by daisy-chaining multiple machines and providing drops/branches for convenient access as required.
No matter the complexity of the machine or motor control system design, tees and reducers provide the flexibility for modular wiring design. Combining tees and drop connectors provide the connection of field devices via a branch connection, while tees with a trunk connector split the main feeder circuit into sub-segments. The PowerCINCH system provides multiple keying options to differentiate circuits on trunk feeder lines.
Receptacles offer a quick-connect interface to the device or cabinet and are well suited for installation on motors and drives to serve as a termination point.
Reusable locking clips snap over the outside of the trunk/feeder or drop/branch connection point, providing a sense of security to the connection points within the PowerCINCH wiring system.
For unused connection/stop points, closure caps are used to maintain the sealing integrity of the system, while providing the flexibility for system expansion.
