摘要： A thermally-sensitive overcurrent protective relay includes a housing case, a bimetal strip bendable in response to an operating current flowing through a control circuit of the overcurrent protective relay, and a movable contact biased by a spring to form a toggle mechanism operable in response to the bending action of the bimetal. A lever supporting bracket mechanically supports the movable contact at a fulcrum portion and electrically connects the movable contact to a terminal. The terminal is mounted in the housing case to conduct current to the control circuit through a contact spring for electrically connecting the lever supporting bracket. This lever supporting member includes a trip current adjusting mechanism adapted to be rotated at its end portion by turning an adjusting screw for adjustment of the operation current.

摘要： A magnetic coil assembly with a connector arrangement which prevents explosion or other accident due to the mismatch of voltage rating between a surge absorber and a magnetic coil, allows only the surge absorber to be changed easily if it has been damaged, and ensures ease of automatically assembling the surge absorber into the magnetic coil assembly. The magnetic coil assembly includes a coil spool, a winding wound around the coil spool, and coil terminals mounted on the coil spool and electrically connected with the winding. The surge absorber is connected mechanically and removably with the coil spool or coil terminals, using connectors that may uniquely relate to the ratings of the absorber and coil, and the absorber terminals of the surge absorber are brought into contact with, and therefore are electrically connected with, the coil terminals.

摘要： Disclosed herewith is a thermally-sensible overcurrent protective relay, which comprises normally-closed contact means, operation means, a plurality of bimetals, a communicating plate, a heater mounted on each bimetal and electrically coupled to at least one of main circuit terminals for a power-source side and a load side, a bimetal retainer electrically coupled to the other main circuit terminal, a first groove, a second groove and a heater holder having a pin fitted in a through hole formed in the bimetal retainer. The operation means opens or closes the normally-closed contact means. The same current as flows through a main circuit to be controlled flows through the bimetals. The communicating plate transmits mechanical deforming force of the bimetals to the operation means so as to open the normally-closed contact means. The heater, when generating heat, causes a mechanical deformation on the bimetals. The bimetal retainer secures one end of each bimetal. The first groove securely holds the main circuit terminals, while the second groove securely holds a connecting section between the bimetal retainer and the bimetals.
