國家電氣和UL/CSA。在德國，要求在電流供應和電線尺寸減小的地方提供過電流保護。除此之外，《憲法》還規定，應根據其當前的資金狀況對罪犯進行保護。有特定的情況需要應用額定值，如電機電路和變壓器保護選擇指南。Bulletin M斷路器的額定值應符合UL，pa的規定。因此，如果斷路器與連續負載一起使用，其額定值應不超過%。線路和負載可顛倒。Bulletin M斷路器可為底部饋電。M斷路器Publicati HR額定值公告M斷路器額定值為UL規定的加熱、空氣冷卻和制冷斷路器，第頁。并且可以用于這種類型的應用。SWD額定值公告M斷路器。額定值為開關負載SWD，因此可用于將熒光燈照明負載切換至其電流和電壓最大值。公告M斷路器被評為UL規定的電流限制斷路器，第頁。。Bulletin M系列的特點是能夠比初始斷路器更有效地實現短路中斷。在交流斷路器中，短路中斷時間要求約為正弦波的一個或兩個半周期。運行時，生成的電流繼續燃燒，直到電流水平通過零。由于t間隙寬度不足，c可能再次點燃。直到c熄滅的電流產生與故障電流的I t值通電能量成比例的加熱效果。Bulletin M裝置的設計目的是大幅減少排放電流的量以及由此產生的排放能量，從而損壞受保護的患者。公告M能夠在故障的前半個周期內中斷短路電流。限制排放電流和能量將防止過度排放的有害影響，主要是避免過熱和機械損壞。如果需要有序停機以最小化人員和設備的危險，則通過選擇最接近過載保護裝置的過載保護裝置來隔離基于故障或過載電路的協調系統。用戶應選擇符合此要求的設備。參考NEC。。參見CEC。協調過電流保護電流限制加熱器負載、照明和其他負載保護公告M斷路器可用于保護加熱器負載、燈光負載和其他負載，遵循制定的指南。參考NEC標準和UL標準，參見CEC和相應的加拿大標準。這兩種貨幣都符合貨幣的聲音。熱能與RMS值的sque成正比，磁力與峰值的sque呈正比。提供保護的最有效方法是實質上限制排放能量。這提供了以下優點：在短路位置的損壞較小。
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.
