    • A solid state overload relay mechanism designed for minimizing the forces required to open an electrical contact associated therewith in the event of a current overload in a protected circuit, and further designed for overcoming residual magnetism in a solenoid initiating the opening of the contact. The contact includes a pair of stationary contacts supported by a base and a pair of movable contact supported by a contact carrier. A latch defines a notch which is normally engaged with a lever. When so engaged, the contact carrier is positioned such that the movable contacts are in contact with the stationary contacts. When the lever becomes disengaged from the latch, the contact carrier is moved and contact between the movable contacts and stationary contacts is broken. The latch is provided with a counterbalance weight to aid in minimizing the force required to return the latch to its original position after the mechanism is tripped. A latch arm extends away from the latch into the path of the lever such that as the lever travels to its extent in an arcuate path, the lever imparts motion on the latch to return it to its initial position, if such has not already occured. An auxiliary stationary contact pair is supported by an auxiliary stationary contact housing and may be selectively installed in either a normally closed or a normally open position.
    • 一种固态过载继电器机构,其设计用于在受保护电路中的电流过载的情况下最小化打开与其相关联的电触点所需的力,并且进一步设计用于克服螺线管中产生触点开启的剩余磁性。 触点包括由基座支撑的一对固定触点和由触点载体支撑的一对可动触头。 闩锁限定了通常与杠杆接合的凹口。 当接合时,接触载体被定位成使得可动触头与静触点接触。 当杠杆从闩锁脱离时,触点支架移动,可动触头和固定触点之间的触点断开。 闩锁设置有平衡重,以帮助最小化在机构跳闸之后将闩锁返回到其初始位置所需的力。 闩锁臂从闩锁延伸到杠杆的路径中,使得当杠杆以弓形路径行进到其范围时,杠杆将闩锁运动以将其返回到其初始位置,如果还没有发生。 辅助固定触头对由辅助固定触头壳体支撑,并可选择性地安装在常闭或常开位置。

    • A residuel current circuit breaker (1) has a partition wall (3) which separates an over-current protection device (4) from a residual current detection circuit (5). A plunger rod (24) extends through a bore (23) in the armature (21) of a coil (20) and is moved independently through the coil (20) to trip the breaker if a residual current is detected by the circuit (5). The plunger rod (24) is moved by a drive rod (31), the operation of which is controlled by a permanent magnet (35) which retains the drive rod (31) retracted and an electromagnet (30) which allows the drive rod (31) to drive forwardly under the action of a spring (32) in the event of a residual current being detected. The plunger rod (30) is reset by a reset lever (40) which is moved when an operating handle (18) of the breaker moves from a non-tripped to a tripped position on tripping of the breaker.
