Description
CORT POWER CP4W-1252P ā 125A Quad Automatic Transfer Switch ā 120/240VĀ 1-Phase ā NEMA 3R
The CORT POWER CP4W-1252P Automatic Transfer Switch is a compact, outdoor-rated power transfer solution engineered for applications requiring multiple independent single-phase transfers from a single enclosure.
This model features four (4) fully independent 125A automatic transfer switches, each with its own built-in transfer switch controller, factory-installed inside one NEMA 3R outdoor enclosure. The result is a cleaner installation, reduced material and labor costs, and simplified generator integration compared to traditional single-ATS setups.
Designed for reliability, flexibility, and ease of installation, the CP4W-1252P is ideal for multi-meter and multi-load standby generator applications.
Key Features
- 125 Amp Rating (per ATS)
- Quad ATS Configuration ā four independent ATS units in one enclosure
- Integrated Controllers ā each ATS includes its own transfer switch controller
- 120/240V, Single Phase
- 2-Pole Open Transition (Break-Before-Make)
- 2-Wire Dry Contact Generator Control
- Outdoor-Rated NEMA 3R Enclosure
- Reduced Footprint ā fewer enclosures, fewer conduits, cleaner installs
- Service-Friendly Internal Layout for simplified wiring and maintenance
What Makes the CP4W-1252P Unique
Most transfer switch installations require one ATS per meter or load, increasing wall space requirements, conduit runs, and installation cost.
The CORT POWER CP4W-1252P consolidates four fully independent ATS units into a single enclosure, providing:
- Lower installation labor and material costs
- Reduced wall space requirements
- Simplified generator start/stop wiring
- Centralized service and troubleshooting access
This design is especially effective for sites with multiple meters or critical circuits supplied by a single generator.

Typical Applications
The CP4W-1252P is commonly used in applications where multiple independent electrical meters or loads require automatic transfer from a single generator source, including:
- Light commercial facilities
- Residential properties with multiple meters
- Condominiums and apartment buildings
- Multi-tenant and mixed-use properties
- Agricultural & irrigation systems
- Telecom shelters
- Multi-load standby generator systems
- Industrial single-phase backup applications
This configuration is ideal where each unit, tenant, or circuit must transfer independently while minimizing installation complexity.

Frequently Asked Questions (FAQ)
Does the CP4W-1252P include a transfer switch controller?
Yes. Each of the four ATS units includes its own dedicated transfer switch controller, allowing independent operation and reliable automatic transfer.
What does āQuad ATSā mean?
Quad ATS means the enclosure contains four fully independent automatic transfer switches, each rated at 125A and each controlling a separate load or meter.
Is the 125A rating shared?
No. The 125A rating is per transfer switch, not shared between circuits.
Can each ATS control a separate load or meter?
Yes. Each ATS is designed to serve an independent load or electrical meter, making this unit ideal for multi-meter installations.
What type of transfer does this ATS use?
The CP4W-1252P uses open transition (break-before-make) transfer to prevent overlap between utility and generator power sources.
How is the generator started and stopped?
The ATS controllers use 2-wire dry contact control to signal the generator to start and stop automatically.
Is this unit suitable for outdoor installation?
Yes. The enclosure is rated NEMA 3R, suitable for outdoor environments and protection against rain and sleet.
Is technical support available?
Yes. The CP4W-1252P is supported by Joval Industrialās technical team for application guidance, installation support, and post-sale assistance.
