Abstract

605,684. Magnets. BRITISH THOMSONHOUSTON CO., Ltd., and WILCOX, T. W. Jan. 3, 1946, No. 269. [Class 35] [Also in. Group XXXVII] An electromagnetic overcurrent relay has two armatures 3, 7, the former acting with a time delay provided by a dash-pot piston 4 on a moderate prolonged overload, and the latter acting instantaneously on a short-circuit to operate a tripping mechanism, the armature 7 having a non- magnetic extension for this purpose. The operating current may be' adjusted by a screw 5. Specification 355,738, [Group XXXVII], is referred to.
