查询词典 overload relay

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.
