Abstract (en)
[origin: WO2010107655A1] An electrical switching apparatus (130) includes a coil (54), a magnetic frame (50) cooperating with the coil, a number of separable contacts (137) controlled by the coil, a number of auxiliary switches (22), a current sensor (114) structured to sense a current (108) flowing through the coil, and a magnetic sensor (120) structured to sense a magnetic field (66,106) of the magnetic frame. A circuit (24) is structured (180) to detect a predetermined characteristic (94) of the sensed current (126) flowing through the coil and output a control signal (27) responsive to the magnetic field being greater than a predetermined value (112) and the predetermined characteristic being detected. The control signal is structured to cause a change in state of the number of auxiliary switches.
