About this file
This document is a set of salient characteristics for two Federal Pacific 15kV pad-mounted switchgear models - the PSE 3 (Catalog No 42100) and the PSE 9 (Catalog No 44222).
The key details include the general specifications of the switchgear, such as voltage rating, bus continuous amperage, and fuse ratings. It outlines the compartment configurations, physical design features including the pad-mount enclosure, 600A dead-break bushings, and 200A load-break fuse compartments (PSE 9 only). The document highlights the critical applications of these switchgear in supporting safe and reliable power distribution grid operations, including fault isolation, circuit backfeeding, and maintenance activities. Lastly, it describes the required physical design characteristics to enable seamless integration within existing base power infrastructure.
This salient characteristics document is related to a federal contract opportunity solicitation (FA441824Q0053) issued by the Department of the Air Force Air Mobility Command for the purchase and delivery of one each of the PSE 3 and PSE 9 switchgear models.

SALIENT CHARACTERISTICS
FEDERAL PACIFIC
PSE 3 – 42100 & PSE 9 – 44222 15kV PAD-MOUNTED SWITCHGEARS
I. GENERAL OVERVIEW.
This memo outlines the key characteristics of the Federal Pacific PSE 3 and PSE 9 15kV Pad-Mount switchgear designed to control, protect, and manage electrical power distribution grids throughout the base infrastructure. These switchgear units are designed to perform switching operations and provide comprehensive protection mechanisms to ensure the safe and efficient operation of connected high voltage equipment assets.
II. SPECIFICATIONS.
PSE 3 - Catalog No 42100 – 15 kV Pad-mounted Switchgear.
PSE 9 – Catalog No 44222 – 15 kV Pad-mounted Switchgear.
At a minimum the equipment and accessories shall possess the following specifications:
Quantity: One (1) each.
Manufacturer: Federal Pacific
Voltage Rating:
- Nominal kV: 15,000 Volts
- Main Bus Continuous Amps: 600 Amp
- Fuse Rating (PSE 9 only): 200 Amp Continuous Load (Part No. S&C – SMU-20)
Compartment Configuration:
- PSE 3 Comp 1: 3- 600 Amp dead break Bushings Comp 2: 3 – 600 Amp dead break Bushings
- PSE 9 Comp 1 & 2: 3 – 600 Amp dead break Bushings Comp 3 & 4: 3 – 200 Amp load break Bushings (Fused)
III. APPLICATIONS:
These Federal Pacific PSE enclosed switchgear are essential for minimizing the exposure of electricians to high voltage hazards during power outages and utility maintenance tasks.
Additionally, these switchgears play a crucial role in isolating grid faults, facilitating the back-feeding of circuits, and enabling loop configurations for facilities or circuits undergoing upgrades or repairs. Their deployment ensures not only the safety of personnel but also the efficiency and reliability of critical electrical operations during maintenance and upgrade activities.
IV. PHYSICAL DESIGN:
The following design characteristics are critical to supports the seamless integration of the switchgear within existing base power grid.
Enclosure Type: Pad-Mount with penta-head cabinet door bolts.
Material: Transformer must be constructed of stainless steel and corrosion proof hardware.
Switch Compartments:
- Equipped with 600 amp rated bushings with removable silver-plated copper threaded studs.
- Provide parking stands adjacent to each bushing to accommodate horizontal feedthroughs and standoff insulators.
- Provided viewing windows within the termination compartments to allow visual verification of switch position, observation of switch-position open/close labels and inspection of blown-fuse indicators on power fuses.
Fuse Compartments (PSE 9 Only):
- Equipped fuse terminals with 200 amp rated bushing wells with removable, silver-plated copper stud designed to accept 200 ampere bushing inserts.
- Provide mechanical interlock on the fuse access panels that guards against gaining access to the fuse before opening the load-break separable insulated connector at the fuse terminal.
- The fuse should only be accessible with a load break elbow removed.
- Provide individual parking stands for each fuse mounting to allow convenient installation of elbow accessories to accommodate grounding.
- Fuse phases shall be equipped with cable guides to assist in cable training and to prevent cables from interfering with movement of the fuse-access panel.
Enclosure grounding:
- Install a ground rod across the full width of the fuse compartments for connecting of cable concentric neutrals.
