1. An Automatic Changeover Switch (ATS) with a 4-pole configuration?
2. A 4-pole contactor or circuit breaker used in automatic power transfer systems?
3. Something else?
Here’s a basic explanation if you meant the first:
Automatic Changeover Switch – 4 Pole
An Automatic Changeover Switch (ATS) is used to switch between two power sources automatically—typically from mains power to a generator or backup power source—when the main power fails.
4-pole means the switch can isolate three phases (R, Y, B) and neutral (N). This is crucial in systems where isolating the neutral is required for safety and proper operation.
Key Components:
Controller: Detects power failure and initiates switching.
Contactor or MCCB: Handles the actual switching.
Timer/Delay circuits: To ensure smooth transitions.
