Zusammenfassung: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 with respect 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.
