What is an automatic transfer switch?
An automatic transfer switch monitors the selected supply conditions and transfers a load between a normal source and an alternate source according to its control logic. It is used where continuity of supply requires an arranged changeover path.
An ATS must be selected as part of the complete distribution system. Rated current, pole arrangement, utilization requirements, transfer sequence, control supply, source conditions and coordination with protective devices all need verification.

Commutateur de transfert automatiqueExaminer les données du modèleHow to choose an ATS
Define both sources, the load and the required transfer sequence before comparing switch series.
Rated current and utilization
Match the connected load, switching duty and upstream protective-device coordination.
Pole and neutral arrangement
Confirm the number of switched poles and the project neutral strategy.
Transfer and control logic
Check operating mode, source monitoring, delays and controller functions by model.
Mechanical integration
Verify mounting, wiring access, operating mechanism and enclosure space.
Define the transfer sequence
Transfer behavior varies by controller and switch series. Confirm the exact sequence before specifying the product.

ATS Selection Questions
Réponses rapides pour une comparaison préliminaire des gammes de produits avant la vérification détaillée des circuits.
What does an automatic transfer switch do?
An ATS transfers a load between two arranged supply sources according to the monitoring and control functions of the selected model.
Which information is needed to select an ATS?
Confirm both source voltages and frequencies, load current, poles, neutral arrangement, switching duty, transfer sequence, control requirements and installation method.
Is an ATS an overcurrent protective device?
An ATS performs switching and transfer. Overload and short-circuit protection must be coordinated with the protective devices specified for the system.
Can every ATS switch a generator supply?
Generator applications require compatible source monitoring, timing, control interfaces and switching ratings. Confirm these functions on the exact series.
What is the difference between automatic and manual transfer?
Automatic transfer uses monitoring and controller logic to initiate the sequence. Manual operation requires an operator action; available modes vary by model.
