国家电气和UL/CSA。在德国，要求在电流供应和电线尺寸减小的地方提供过电流保护。除此之外，《宪法》还规定，应根据其当前的资金状况对罪犯进行保护。有特定的情况需要应用额定值，如电机电路和变压器保护选择指南。Bulletin M断路器的额定值应符合UL，pa的规定。因此，如果断路器与连续负载一起使用，其额定值应不超过%。线路和负载可颠倒。Bulletin M断路器可为底部馈电。M断路器Publicati HR额定值公告M断路器额定值为UL规定的加热、空气冷却和制冷断路器，第页。并且可以用于这种类型的应用。SWD额定值公告M断路器。额定值为开关负载SWD，因此可用于将荧光灯照明负载切换至其电流和电压最大值。公告M断路器被评为UL规定的电流限制断路器，第页。。Bulletin M系列的特点是能够比初始断路器更有效地实现短路中断。在交流断路器中，短路中断时间要求约为正弦波的一个或两个半周期。运行时，生成的电流继续燃烧，直到电流水平通过零。由于t间隙宽度不足，c可能再次点燃。直到c熄灭的电流产生与故障电流的I t值通电能量成比例的加热效果。Bulletin M装置的设计目的是大幅减少排放电流的量以及由此产生的排放能量，从而损坏受保护的患者。公告M能够在故障的前半个周期内中断短路电流。限制排放电流和能量将防止过度排放的有害影响，主要是避免过热和机械损坏。如果需要有序停机以最小化人员和设备的危险，则通过选择最接近过载保护装置的过载保护装置来隔离基于故障或过载电路的协调系统。用户应选择符合此要求的设备。参考NEC。。参见CEC。协调过电流保护电流限制加热器负载、照明和其他负载保护公告M断路器可用于保护加热器负载、灯光负载和其他负载，遵循制定的指南。参考NEC标准和UL标准，参见CEC和相应的加拿大标准。这两种货币都符合货币的声音。热能与RMS值的sque成正比，磁力与峰值的sque呈正比。提供保护的最有效方法是实质上限制排放能量。这提供了以下优点：在短路位置的损坏较小。
Natial Elerical Canadian Elerical and UL/CSA. In geral, the s require that overcurrt protei is at the currt supply and at points where wire sizes e uced. In additi, the s state that cduors be proteed cording to their currt crying capity. There e ecific situatis that require applicati csiderati, such as motor circuit, and guidelines for the selei for transformer protei. The Bulletin M circuit breakers e “n% rated as defined by UL , pa . As such, the circuit breaker's rating should be loaded to no more than % if used with inuous loads. Line and load may be reversed. The Bulletin M circuit breaker may be bottom fed. M Circuit Breakers Publicati HR Rating Bulletin M Circuit Breakers e rated as Heating, Air Cditiing and Refrigerati circuit breakers as defined by UL , pagraph . and may used in this type of applicati. SWD Rating The Bulletin M breakers . A e rated as Switch Duty SWD and as such may be applied to switch fluores lighting loads up to their currt and voltage maximum. Bulletin M Circuit Breakers e rated as currt limiting circuit breakers as defined by UL , pagraph .. The Bulletin M line features the ility to hieve short circuit interruptis f more effeively than cvtial breakers. In cvtial circuit breakers, the short circuit interrupti time requi is approximately e or two half cycles of an sine wave. Wh the ts op, the resulting c inues to burn until the currt level passes through zero. The c may reignite because of the insufficit width of the t gap. The currt that flows until the c is extinguished produces a heating effe proportial to the I t value letthroughergy of the fault currt. The Bulletin M device is designed to substantially uce the amount of letthroughcurrt and the resulting letthroughergy that can damage proteed pts. The Bulletin M has the ility to interrupt short circuit currt within the first half cycle of the fault. Limiting letthrough currt and ergy will prote against the hmful effes of overcurrt and is focused primily avoiding excessive heat and mechanical damage. Where an orderly shutdown is requi to imize the hazds to persnel and equipmt, a system of coordinati based up the faulted or overloaded circuit is isolated by seleive operati of ly the overcurrt proteive device closest to the overcurrt cditi. The user should sele devices that meet this requiremt. RefercesNEC ..so see CEC. Coordinated Overcurrt Protei Currt Limiting Heater Load, Lighting, and Other Load Protei Bulletin M circuit breakers may be used for protei of heater loads, lighting loads, and other loads following the guidelines estlished. RefercesNEC ticle and UL A.so see CEC and appropriate Canadian Standds. Both of these ftors e proportial to the sque of the currt. Thermal ergy is proportial to the sque of the RMS value and magnetic forces e proportial to the sque of the peak value. The most effeive way to provide protei is to substantially limit letthroughergy. This provides the following advantagesF less damage at the locati of the short circuit.
