Lighting Panels - Siemens P1/P2/P3/C1/C2 Series

This new generation of Lighting Panel products represents the high level of engineering innovation expected from Siemens. With flexibility and strength added to the existing rugged and durable panelboard family, Siemens Lighting Panels are extremely easy to install. These newer designs also simplify wiring and reduce material requirements, saving additional installation time. Siemens also offers Unassembled Panelboards (UPB), which are designed to meet shorter lead time requirements.

Features and Benefits

Revised P1 Lighting Panels

  • Convertibility: Field convertible main breaker (MB) and main lug kits (MLO), (through 400 amps), will allow you to switch from main lug to main breaker, and vice versa with no change in box size or additional cabling.

  • Flexibility: Field addable sub-fed breakers (up to 250 amps) or Feed-Thru lug kits can be field installed without utilizing any of your feeder breaker positions or increasing your box height (when Feed-Thru option is chosen).

  • Ease of Installation: Lay-in construction and or removable lugs make wiring the main and neutral lugs easier and faster.

  • Invertible: Unique design allows panel to be be inverted in the field and keep its labeling legible.

  • New Revised P1 factory-assembled allow for non-Feed-Thru options which do not include a sub-feed space.

  • Extended Circuits are now available in factory-assembled panels:
    > P1-250A has both FT and NFT variations for all circuits: 18, 30, 42, 54, and 66 (xGB panels are only available as FT).
    > P1-400A has both FT and NFT variations for 30, 42, 54, circuits only (xGB panels are only available
    as FT). P1-400A is not available in 18 circuit variations
        - The 66 circuit variation of 400A is only available in NFT due to enclosure size limit of 74" high

  • The Unassembled P1 Program (UPB) has many of the factory-assembled features but is limited to 18, 30, 42, and 54 circuit 250A panels and 30, 42, and 54 circuit 400A panels.
    > Limited system voltages available.
    > Only Feed-Thru variations available - all include sub-feed space.


P2 Lighting Panels

Flexibility is the hallmark of the P2 panel. This panel offers a wide array of factory-assembled options to meet almost all lighting panel applications.

  • With this design, the ability to mix breaker frames in unit space up to 250 amps will also meet many distribution panel requirements in a much smaller package.

  • Bussing options for the P2 vary from the typical temperature rated to 750 A/Si aluminum to 1000A/Si copper.

  • Standard bussing in the P2 panel is tin-plated. Silver-plated copper is also offered as an option.

  • Integrated time clocks, bus mounted contactors, as mains or sub mains, split bus, and sub-feed lugs (up to 400 amp) are just a few of the options of this unique panel.

Like a lighting panel, P2 is set up around 18, 30, 42, 54, 66, 78, and 90 circuit configurations.

  • It will also allow the user to configure the panel to the smallest possible size. The P2 panel starts with 9" of unit space (18 circuits of 1" pole breakers).

  • Breakers mounted in unit space can be mixed and matched to meet customer requirements. All 1" pole breakers (BL, BQD, ED frames) are mounted in 3" or 6" pole increments. Breaker frames, above 125 amps, are mounted in 6" single breaker mountings.


P3 Lighting Panels

Another innovation from Siemens is the P3 panel. It is a smaller, footprint distribution panel to fit a large number of applications that require more (or larger) branch devices than the lighting panel class offer. This panel offers a wide array of factory-assembled options, and has the ability to mix breaker frames in unit space up to 250 amps.

  • Bussing options for the P3 vary from the standard temperature aluminum to temperature rated copper, 750 A/Si aluminum, and 1000A/Si copper designs.

  • All bussing in the P3 panel is tin-plated as a standard. Silver-plated copper is offered as an option on a copper bus.

  • Integrated time clocks, bus mounted contactors, as mains or sub mains, split bus and sub-feed lugs (up to 400 amp) are just a few of the options of this unique panel.

The P3 panel configurations, defined by the unit space, allow for a given amperage, main device, and box height.

  • The P3 panel starts with a 56" high box. Breaker unit space can be mixed and matched to meet customer requirements.

  • All 1" pole breakers (BL, BQD, ED, xGB frames) are mounted in 3" or 6" pole increments.

  • Breakers frames, above 125 amps, are mounted in 6" single or twin breaker mountings.
