Description
CORT POWER CP5W-1252P ā 125A 5-way Automatic Transfer Switch ā 120/240VĀ 1-Phase ā NEMA 3R
The CORT POWER CP5W-1252P Automatic Transfer Switch is an outdoor-rated, multi-circuit power transfer solution designed specifically for sites with five independent meters or loads served by a single standby generator.
This model integrates five (5) fully independent 125A automatic transfer switches, each equipped with its own built-in transfer switch controller, all factory-assembled into one NEMA 3R enclosure. By consolidating multiple ATS units into a single cabinet, the CP5W-1252P significantly reduces wall space requirements, conduit runs, and overall installation complexity.
The result is a clean, scalable solution for multi-tenant, residential, and light commercial standby power systems.
Key Features
- 125 Amp Rating (per ATS)
- Five-Way ATS Configuration ā five independent ATS units in one enclosure
- Integrated Controllers ā one controller per transfer switch
- 120/240V, Single Phase
- 2-Pole Open Transition (Break-Before-Make)
- 2-Wire Dry Contact Generator Control
- Outdoor-Rated NEMA 3R Enclosure
- Optimized for Multi-Meter Installations
- Installer-Friendly Layout for simplified wiring and service
Designed for Multi-Meter Applications
Many residential and commercial facilities require independent power transfer for each electrical meter, traditionally forcing installers to mount multiple standalone ATS enclosures.
The CORT POWER CP5W-1252P simplifies this by housing five complete ATS assemblies in one enclosure, offering:
- Cleaner electrical rooms and exterior walls
- Reduced material and labor costs
- Simplified generator start/stop wiring
- Centralized access for inspection, service, and troubleshooting
This configuration is especially valuable where space, aesthetics, and inspection efficiency matter.

Frequently Asked Questions (FAQ)
Does each transfer switch include its own controller?
Yes. All five ATS units include dedicated, built-in controllers, allowing each load to operate independently.
Is the 125A rating shared across circuits?
No. Each ATS is individually rated up to 125 amps.
Can each ATS serve a separate meter?
Yes. The CP5W-1252P is specifically designed for multi-meter installations, with each ATS controlling a separate service.
What type of transfer does this unit provide?
This model uses open transition (break-before-make) switching to eliminate any overlap between utility and generator power.
Is the enclosure suitable for outdoor installation?
Yes. The enclosure is rated NEMA 3R, suitable for outdoor exposure to rain and sleet.
