Thermal-Magnetic Circuit Breakers are supplied with Calibrated Fixed Thermal and Adjustable Magnetic Trip Functions.
The Magnetic Trip Function is adjusted by a single slider that simultaneously adjusts the Instantaneous trip point of each pole. 
This Adjustable Instantaneous Trip Characteristic is Factory Set at the Minimum Setting allowing the Circuit Breaker
to interrupt short circuit overcurrent with no intentional delay. 
In a Motor Load Application this setting can be adjusted to allow for more inrush Current as the Motor reaches normal operating RPM. 
For Multi-Family Residential Applications this Minimum Setting is typically the desired setting.
