Single Phase Din Rail 2P 125A AC 220V ATS Dual Power Automatic Transfer Electrical Selector Switches Uninterrupted Power
Single Phase DIN Rail 2P 125A AC 220V ATS Dual Power Automatic Transfer Switch – Uninterrupted Power Supply Selector
Product Overview
Ensure reliable and continuous electrical power with the Single Phase DIN Rail 2P 125A AC 220V Automatic Transfer Switch (ATS). Designed for single-phase electrical systems, this automatic transfer switch intelligently switches between two available power sources, helping maintain power to connected loads when the primary power supply becomes unavailable.
With a 2-pole configuration, 125A rated current, and 220V AC operating voltage, this compact DIN-rail-mounted ATS is suitable for residential, commercial, and light industrial electrical installations where dependable power transfer is required.
The switch is designed to automatically detect a failure, interruption, or abnormal condition in the primary power source and transfer the load to the secondary power source. When the primary source returns to an acceptable condition, the system can automatically transfer the load back, depending on the device’s operating configuration.
Its compact DIN-rail design makes it convenient for installation inside distribution boards, electrical cabinets, control panels, and other compatible enclosures.
Key Features
Automatic Dual-Power Transfer
Automatically transfers an electrical load between two power sources when the preferred power supply becomes unavailable or falls outside the acceptable operating range.
125A High-Current Capacity
Rated up to 125A, making the switch suitable for high-current single-phase circuits when correctly matched with the electrical installation, wiring, protective devices, and connected load.
Single-Phase 2P Configuration
The 2-pole design allows switching of the applicable conductors in a single-phase electrical system, providing a practical solution for dual-source power management.
AC 220V Operation
Designed for 220V AC single-phase applications, making it suitable for many residential, commercial, backup-power, and small industrial electrical systems.
DIN Rail Mounting
The compact DIN-rail format allows convenient installation inside compatible electrical distribution boxes, consumer units, switchboards, and control cabinets.
Automatic Source Switching
The ATS monitors the designated power sources and initiates source transfer when the operating conditions require it, reducing the need for manual intervention.
Backup Power Compatibility
Can be used as part of a backup-power arrangement involving sources such as utility power and an appropriate generator, inverter, UPS, or other compatible secondary power source.
Space-Saving Design
Its modular DIN-rail construction helps save valuable panel space compared with larger conventional transfer-switch assemblies.
How It Works
The ATS is connected to two separate electrical power sources:
Power Source 1 – Primary/Preferred Supply
Normally supplies electricity to the connected load.
Power Source 2 – Backup/Secondary Supply
Provides power when the primary source is unavailable or unsuitable.
During normal operation, the connected load is supplied by the designated primary source. If the ATS detects an interruption or qualifying abnormal condition, it automatically changes over to the secondary source.
When the primary supply is restored and meets the required operating conditions, the ATS can transfer the load back to the primary source according to its programmed or built-in operating sequence.
This automatic transfer process helps reduce downtime and provides a more convenient alternative to manually changing between power sources.

Before installation:
- Confirm that the ATS voltage and current ratings match the electrical system.
- Verify the compatibility of both power sources.
- Confirm the correct wiring arrangement using the manufacturer’s wiring diagram.
- Select appropriately rated cables and protective devices.
- Ensure the DIN rail and electrical enclosure are suitable for the installation.
- Confirm that the connected load does not exceed the applicable rating.
- Follow all local electrical codes and installation requirements.
- Disconnect and isolate all electrical power sources before carrying out installation or maintenance.
Safety Information
WARNING: This is an electrical switching device intended for installation in an appropriate electrical system. Incorrect installation or wiring can result in electric shock, fire, equipment damage, or serious injury.
Do not exceed the specified electrical ratings. The 125A rating should not be interpreted as meaning that every installation can safely operate continuously at 125A; cable size, protective devices, ambient conditions, enclosure requirements, load characteristics, and applicable electrical regulations must all be considered.
Never connect two incompatible or unsynchronized power sources in a manner that could cause them to become electrically interconnected. Ensure the ATS is suitable for the specific type of primary and backup sources being used.
