Abstract (en)
[origin: EP1103989A2] The relay coil (4) operates a spring loaded armature (5) which actuates circuit breaker contacts (P) through a linkage (9a,L). In the coil de-energized state the magnetic circuit includes permanent magnets but these are by-passed when the coil is energized. The fixed and moving parts of the magnetic circuit are built up from laminations which have greater width at fixing points
