    • Embodiments of a combination motor starting device and protector module including a motor start winding cut-out switch for an electric motor are described. In the one embodiment, the motor protector (38) includes a heater element (40) and a bimetallic protector switch (32), electrically connected in series and configured to be coupled between a power source and the motor windings (26,28). The bimetallic protector switch includes a stationary contact (44), a movable contact, and a bimetal element, responsive to current flow through the protector, controls movements of the movable contact. The heater element (40) is positioned in heat transfer relationship with the protector bimetal element. The motor starting device, in one form, is a positive temperature coefficient resistor (PTCR) element (30) configured to be connected in circuit with the motor start winding (28). A bimetallic cut-out switch is connected in series with the PTCR. The bimetallic cut-out switch includes a movable conducting element (34), and a bimetal element (36) controls movement of the movable conducting element. The bimetal element of the cut-out switch is positioned in heat transfer relationship with the above described heater element (40).
    • 描述了一种组合电动机启动装置和保护器模块的实施例,其包括用于电动机的电动机起动绕组开关开关。 在一个实施例中,马达保护器(38)包括加热元件(40)和双金属保护开关(32),其串联电连接并且被配置为耦合在电源和马达绕组(26,28)之间。 双金属保护器开关包括固定触点(44),可移动触点和双金属元件,响应于流过保护器的电流,控制可动触头的运动。 加热器元件(40)与保护器双金属元件传热关系。 一种形式的电动机起动装置是构造成与电动机起动绕组(28)电路连接的正温度系数电阻(PTCR)元件(30)。 双金属切断开关与PTCR串联连接。 双金属切断开关包括可移动导电元件(34),双金属元件(36)控制可移动导电元件的移动。 切断开关的双金属元件与上述加热器元件(40)的热传递关系定位。
