摘要： PROBLEM TO BE SOLVED: To provide an outer shell case structure for securing stable overload and phase interrupting operation characteristics by reducing thermal interference given to a heater unit in a S phase by R, T phases located adjacent to each other on both right and left sides across an interphase barrier. SOLUTION: Inside the outer shell case 14 of the thermal overload relay, heater unit chambers 14R, 14S, 14T in R, S, T phases arranged side by side across the interphase barriers 14a are defined where the heater units 1 in phases are arranged individually element by element. As a means for reducing thermal interference given to the heater unit in the S phase held between the R phase and the T phase by the R phase and the T phase, a recessed site 14d is formed outward in the outer shell case 14 so that a space of the heater unit chamber 14S in the S phase defined between the R phase and the T phase arranged side by side across the interphase barrier 14a is parted therefrom to be smaller than the heater unit chambers 14R, 14T in the R phase and T phase located adjacent to each other on both sides.

摘要： A reset rod 43 of a thermal overload relay is configured to be switchable between a manual reset position in which a reversal mechanism 21 is manually returned to an initial state prior to reversal by performing a pushing-in operation, and an automatic reset position in which a pushed-in state is held by a pushing and rotating operation from this manual reset position, and the reversal mechanism 21 is automatically returned to the initial position. In addition, axial runout restriction portions 17b, 17d, 51, 46 and 47, which restrict axial runout of the reset rod 43 when the reset rod 43 is held in the automatic reset position, are provided.

摘要： PROBLEM TO BE SOLVED: To improve the support mechanism of a heater unit in order to maintain its operation characteristics stably without being affected by deformation of a press-fitted support part caused by electric conduction and heat generation in the heater unit accommodated in an enclosure case.SOLUTION: A thermal type overload relay incorporates a heater unit 4 of a main bimetal 7 connected to each phase of a main circuit and a contact make-and-break mechanism linked to the main bimetal via a shifter in an enclosure case 1 made of mold resin and consisting of a case body 2 and a case cover 3. The heater unit 4 is constructed in such a way that the base part of its main bimetal 7 is joined to a support plate 8 by a T joint, and that the case body 2 and the case cover 3 have press-fitting ribs 2d and 3a formed integrally therewith, which sandwiches the support plate 8 of the heater unit 4 in between from front and rear, the front and the rear parts of the support plate 8 being inserted under pressure into the press-fitting ribs 2d and 3a to hold the main bimetal 7 in an upright posture, whereby the posture of the main bimetal 7 is restrained from changing to a direction of curvature as will be caused by relaxation of residual stresses in, or creep deformation of, resin molded articles.

摘要： A thermal overload relay includes main bimetals which bend upon detection of an overload current; a release lever displaced via movement of a shifter moved in response to the bending of the main bimetals; and a contact reversing mechanism for changing-over contacts responsive to a rotation of the release lever. The main bimetals, the release lever and the contact reversing mechanism are all disposed in a case. The contact reversing mechanism includes a pivotable movable plate; a reversing spring reversing the movable plate by coupling with a rotated release lever; and an interlock plate rotating around a support shaft together with the movable plate. Each contact has a normally opened contact piece and a normally closed contact piece and is disposed respectively in the vicinity of a front surface and in the vicinity of a back surface of the interlock plate.

摘要： PROBLEM TO BE SOLVED: To improve a shape of a release lever by which a reverse spring is operated in order to stabilize an operation current value of a thermal overload relay.SOLUTION: The thermal overload relay has an outer shell case in which a main bimetal bent and displaced by conduction of an overcurrent, a shifter displaced responding to the bending of the main bimetal, a release lever rotated by the displacement of the shifter through a support shaft, and a contact reversing mechanism driven by the release lever are internally installed. The contact reversing mechanism comprises an assembly of a reverse spring linked with the release lever, a slider coupled to the reverse spring, an output contact which performs open/close operation in response to the movement of the slider, and a reset button. A press part of the release lever, which presses an action part of the reverse spring in order to trip the reverse spring, is made to have a line contract structure against the axial direction of the support shaft.
