They are usually used for AC 220v /50Hz one phase motors to protect motor from over temperature caused by unusual state such as overload, blocked up. They are also used for protecting against over temperature temperature control in heater, fluorescent ballast, IC etc. 2 結(jié)構(gòu)特點(diǎn) Characters BH 系列熱保護(hù)器是采用一定幾何形狀的雙金屬片，無需輔助機(jī)構(gòu)，僅靠雙金屬片的自身感溫和 電流熱效應(yīng)，使雙金屬元件的狀態(tài)發(fā)生快速變化，直接帶動(dòng)觸點(diǎn)實(shí)現(xiàn)自動(dòng)切斷和接通電路，起到過 熱、過載保護(hù)作用，解決了電流突增，感溫滯后的問題。具有內(nèi)阻小、體積小、密封牢固、比通常保護(hù)器更安全更靈敏等優(yōu)點(diǎn)。 The bimetal with its own small geometrical form is one of the most important parts. There are no other assistant parts in BH series thermal protector. The bimetal is also sensitive to temperature and current, if it is be place in circuitry in series. When it is reach the acting temperature in circuitry, the bimetal will rapidly act then cutting off or connecting the circle. 3 產(chǎn)品分類、型號及外形結(jié)構(gòu)：Type Configuration 3.2 外形及結(jié)構(gòu) Configuration 熱保護(hù)器的外形及結(jié)構(gòu)見總裝圖。Configuration refers to assembly drawing 4. 觸點(diǎn)最大電容量 Contact Capacity ：AC250V/6A、AC125V/8A 5．技術(shù)性能 Technique Ability 5.1 外觀性能 Appearance Performance 5.1.1 熱保護(hù)器的外殼不得有毛刺、裂紋、變形、銹蝕等現(xiàn)象。 There is no burr, crack, distortion and rust on case. 5.1.2 標(biāo)志應(yīng)正確、端正、清晰、經(jīng)久耐擦。 Marks should be correct ,clear and durability. 5.2 引線（端子）抗拉性能 Pull Endure Ability of leads with terminal 熱保護(hù)器的引線（端子）應(yīng)能承受不低于 30N 軸向靜拉力，歷時(shí) 5 秒，應(yīng)無斷裂、松動(dòng)、脫落 現(xiàn)象。 Terminals leads should endure more than 30N axes direction pull lasting for 5 seconds.
