    ⚡ Comprehensive Circuit Breaker Testing with AMT 205
    
    Reliable circuit breaker performance is critical for power system protection and operational safety. The AMT 205 is designed to perform essential diagnostic tests that help engineers accurately evaluate breaker condition and performance.
    -----------------------------------------------------
    🔍 Key Tests with AMT 205:
    ✔ Timing Test
    Measure opening and closing times to verify correct breaker operation
    ✔ Minimum Pickup Test
    Determine the minimum operating voltage required for breaker actuation
    ✔ Contact Resistance Measurement
    Evaluate the health of main contacts and detect excessive resistance
    ✔ DRM (Dynamic Resistance Measurement)
    Analyze contact movement and internal condition during operation
    -----------------------------------------------------
    🚀 Why AMT 205?
    By combining multiple critical tests in one device, AMT 205 enables:
    ✔ Faster diagnostics
    ✔ Improved reliability assessment
    ✔ More efficient maintenance of circuit breakers
