Slow trip breaker
WebbCurve 1 should always trip last in a discriminated system as it has a slower tripping curve than a curve 2. Curve 1 is the orange toggle breaker that is a slow tripping circuit breaker, has a 10-20x inrush current, whereas Curve 2 has a 5-10x inrush current rating. WebbCircuit breakers meet UL 489 requirements for branch circuit protection, so they protect downstream equipment and wiring from overloads and short circuits. Circuit breakers with ground fault sensitivity will trip if they detect a current leak above 6mA. This minimizes the risk of electric shock to workers and equipment.
