- Pow-R-Line 4B panel board utilizes circuit breakers. Pow-R-Line 4F Panelboards utilizes types FDPW fusible switches.
- A single chassis accommodates both circuit breakers and fusible switches.
- Main and neutral are located at the same ends to provide additional space for branch devices.
- Three-piece trim facilities installations.
- Will accommodate Series C Circuit Breakers to provide higher ratings in a standard chassis and increased series ratings.
- UL tested and listed. Meets NEC and NEMA tandards.
General Construction Features
WESCOSA assembled Panelboards as per Cutler-Hammer technologies are designed for sequence phase connection of branch circuit devices. This allows complete flexibility of circuit arrangement (1-, 2- or 3-poles) to allow balance of the electrical load on each phase.Sturdy rigid chassis assembly assures accurate alignment of interior with panel front; prevents flexing and minimizes possibility of loosening or damage to current carrying parts during and after installation.Four-point in-and-out adjustment of panel interior is provided to meet critical depth dimension on flush installations. This compensates for possible alignment of box at installation. Main lungs are mechanical solder less type and approved for copper of aluminum conductors.
