摘要： An overload relay includes a base (22) with electrical contacts (162, 164) thereon. A lever (116) including a contact actuator (140) is in proximity to the contacts (162, 164) and a pivot (122) mounts the lever (116) on the base (22) for pivotal movement between first and second positions. A releasable latch (106) normally holds the lever (116) in a particular one of the positions and a spring (144) is interposed between the base (22) and the lever (116) at a location spaced from the pivot (122) to bias the lever (116) toward the other of the positions by applying a bias thereto in a generally predetermined direction. The direction and location are such that when the lever (116) is in a latched position, the bias will provide a relatively small force tending to move the lever (116) toward the unlatched position and further is such that as the lever (116) moves towards the first position, the bias produces an increasing force tending to move the lever (116) towards the unlatched position.

摘要： A switching device for the interruption of a fault current includes a housing having first and second electrical connectors for connection in the path of an electrical conductor carrying a single current phase. A vacuum switching chamber is disposed in the housing. A current transformer disposed in the housing includes a primary circuit connected between the first and second terminals for conducting the single current phase and inducing a corresponding current in a secondary winding. A magnet actuator disposed in the housing is electrically coupled to the transformer secondary winding. The magnet actuator is responsive to a fault current in the transformer primary, by way of the corresponding current in the secondary, for changing from an inactive state to an actuated state. A latch disposed in the housing is connected for latching the movable switch contact in a closed position and for being unlatched in response to a change to the actuated state of the magnet actuator for moving the movable switch contact to an open position. A turn-off spring causes the latch to move the movable switch contact away from the stationary switch contact when the latch becomes unlatched.

摘要： A circuit breaker includes a compressive turning spring hung between a movable contact arm pivoted at an end to a handle rotatably mounted to a first reference position and a cradle pivotably mounted to a second reference position and disengageably locked to an abnormal current detection and trip mechanism. Under normal operation of the breaker, the turning spring exerts a contact pressure between movable and fixed contacts. Upon detection of an abnormal current, the turning spring is caused to turn so as to open the contacts. With this arrangement, the dispositions of constituent elements and their interlocking assembly can be simplified.

摘要： A multi-pole circuit interrupter comprising first and second pole units separated by a partition wall in a housing, each of the pole units having a pair of separable contacts. The contacts of the first and the second pole units are connected by a cross bar for simultaneous movement. An operating mechanism is disposed in the first pole unit for separating the contacts in response to an overcurrent flowing through the interrupter. An alarm switch is disposed in the second pole unit for indicating the tripping of the operating mechanism, and an actuator is disposed between the operating mechanism and the alarm switch for detecting the tripping of the operating mechanism and actuating the alarm switch. The actuator comprises a rotatable shaft supported in the housing and extending through the partition wall including a substantially circular opening having a diameter slightly larger than that of the rotatable shaft, an actuator arm secured to one end of the rotatable shaft for movement caused by the tripping action of the operating mechanism, and an actuator level secured to the other end of the rotatable shaft for engaging and actuating the alarm switch.

摘要： A circuit breaker with an auxiliary switch actuator mechanism is disclosed. The actuator mechanism includes an actuator member and a locking member. Upon resetting of the breaker, the actuator member is moved by the arm carrying the movable contact of the main breaker mechanism to a position where it is locked by the locking member. Tripping the breaker causes the locking member to unlatch and release the actuator member to switch the auxiliary switch contact to allow indication of the tripped state, while manual operation of the breaker does not alter the condition of the auxiliary switch.
