Abstract (en)

[origin: CA2001846A1] 11 MAGNETIC TRIP DEVICE WITH WIDE TRIPPING THRESHOLD SETTING RANGE A magnetic trip device having two plunger cores cooperating respectively with polar parts of a fixed magnetic circuit excited by a coil. The effects of the plunger cores are opposing, and by adjusting the initial position of the moving core assembly constituted by these two plunger cores, the tripping threshold can be adjusted with a large amplitude. Refer to figure 1.
