An adjustable trip assembly is for an electrical switching apparatus. The electrical switching apparatus includes a housing, separable contacts and an operating mechanism for opening and closing the separable contacts. The adjustable trip assembly includes a load conductor, a magnetic assembly comprising a magnetic member and an armature movably coupled to the magnetic member, and a calibration assembly comprising a calibration bracket cooperating with the armature, and an adjustment mechanism being adjustable to move the calibration bracket and thereby adjust the position of the armature withrespect to the magnetic member to calibrate the magnetic assembly. The magnetic assembly further includes a biasing element that biases the armature away from the magnetic member. 种可调节的跳闸组合件用于电气开关设备。所述电气开关设备包含外壳、可分离触点和用于打开和闭合所述可分离触点的操作机构。所述可调节的跳闸组合件包含：负载导体；磁性组合件，所述磁性组合件包括磁性构件和可移动地耦合到所述磁性构件的电枢；和校准组合件，所述校准组合件包括与所述电枢协作的校准托架和可调节以移动所述校准托架并且由此调节所述电枢相对于所述磁性构件的位置以校准所述磁性组合件的调节机构。所述磁性组合件进步包含将所述电枢偏置远离所述磁性构件的偏置元件。
