The motor is provided with a thermal motor protector (a protective device that is sensitive to both temperature and current) that prevents the temperature of the motor windings from becoming more than 125°(257°) under the maximum load C F under which the motor runs without causing the protector to cycle, and from becoming more than 150°(302° with the rotor of the motor locked; or C F) 4 The motor complies with the requirements for impedance-protected motors; b Under wiring, unless the wiring complies with the VW-1 (Vertical-Specimen) Flame Test in the Reference Standard for Electrical Wires, Cables, and Flexible Cords, UL 1581; c Under an unenclosed switch, transformer, relay, solenoid, and the like, unless it 7 舞台灯标准 can be shown that malfunction of the component does not result in a fire; or d Under field- and factory-made splices and overload and overcurrent protection devices.

F C F 4 发动机符合阻抗保护发动机的要求； b 配线，除非电线符合VW-1及参考UL 1581标准的有关电线，电缆及线芯灵活性的焰火测试。 c 未封装的开关，变呀器，继电器，螺线管及与其相似的，除非它可显示元件的故障不会引起火灾。 d 在户外和生产工厂接合过载和过流保护装置。

Which explained "" overcurrent trip behavior: as the relay for other contacts are fine speed controller and current regulator of input and output signal both the normal value of zero growth of the original does not work contact for some reason (such as vibration, etc.) to work, all of a sudden phase-limiter had lifted the blockade and the output signal, so that the larger main motor Haar "" transflux arising from the trip.

由此也可注释呈现&功不源&跳闸本体的来因：由于该继电器的其他触不面均处事精良，速率调度器和电不源调度器的不不不不不不不输入、不不不不不不不输入暗记均呈变态的由不整到必不退值的落低，而本来不处事的触不面由于某种来因猝然又处事了，移相限制器便因撤废敞开而不不不不不不不输入较大暗记，使宾电机不不矮速启不静而呈现&功不源&跳闸本体。
