Circuit Breakers 1. An inrush current fl ows during the minimum power application time. AF20: approximate 0.4A,

AD24: approximate 1.2A
2. GT3F does not read the preset time range shown on the knob after power is turned off. Note that minimizing
the preset time, by turning the knob to zero, does not shorten the delay time after power is removed.
