塑殼電動(dòng)機(jī)保護(hù)CDM3-160H/33002 100A
產(chǎn)品概述
CDM3-160H/33002 100A塑殼電動(dòng)機(jī)保護(hù)器是專為工業(yè)電動(dòng)機(jī)保護(hù)設(shè)計(jì)的智能控制裝置，適用于交流380V/415V低壓系統(tǒng)。該產(chǎn)品采用熱磁式脫扣技術(shù)，具有精確的過(guò)載和短路保護(hù)功能，能有效防止電動(dòng)機(jī)因電流異常導(dǎo)致的設(shè)備損壞。其殼架電流為160A，額定工作電流可調(diào)范圍為100A，適用于三相異步電動(dòng)機(jī)的直接啟動(dòng)和保護(hù)場(chǎng)景。產(chǎn)品設(shè)計(jì)符合工業(yè)環(huán)境要求，結(jié)構(gòu)緊湊且安裝便捷，支持板前接線和固定式安裝方式。16
核心功能特點(diǎn)
該保護(hù)器具備多重保護(hù)機(jī)制，包括瞬時(shí)短路保護(hù)和反時(shí)限過(guò)載保護(hù)。熱磁脫扣單元能在10-12倍額定電流下實(shí)現(xiàn)快速分?jǐn)啵ㄋ矔r(shí)脫扣），同時(shí)通過(guò)雙金屬片機(jī)構(gòu)對(duì)持續(xù)過(guò)載電流進(jìn)行延時(shí)保護(hù)。產(chǎn)品分?jǐn)嗄芰_(dá)35kA（400V時(shí)），可有效抑制故障電流對(duì)電網(wǎng)的沖擊。四極型號(hào)中的N相設(shè)計(jì)分為A/B兩種類型：A型N相不參與過(guò)電流保護(hù)但保持常通狀態(tài)，B型N相與其他三極同步分合，滿足不同配電系統(tǒng)的需求。17
技術(shù)參數(shù)詳解
產(chǎn)品額定絕緣電壓為800V，沖擊耐受電壓8kV，機(jī)械壽命達(dá)20,000次（無(wú)維護(hù)條件）。外形尺寸為75mm(寬)×130mm(高)×68mm(深)（3極型號(hào)），重量約0.78kg。脫扣特性曲線經(jīng)過(guò)優(yōu)化，能準(zhǔn)確區(qū)分電動(dòng)機(jī)啟動(dòng)電流與故障電流，避免誤動(dòng)作。在690V電壓環(huán)境下仍保持穩(wěn)定性能，特別適用于礦山、石化等嚴(yán)苛工業(yè)場(chǎng)合。產(chǎn)品提供復(fù)式脫扣、電磁式脫扣等多種配置選項(xiàng)，用戶可根據(jù)負(fù)載特性靈活選擇。19
應(yīng)用場(chǎng)景與優(yōu)勢(shì)
CDM3-160H/33002廣泛應(yīng)用于風(fēng)機(jī)、水泵、壓縮機(jī)等動(dòng)力設(shè)備的保護(hù)系統(tǒng)。其優(yōu)勢(shì)體現(xiàn)在：1）采用模塊化設(shè)計(jì)，維護(hù)簡(jiǎn)便；2）手柄操作機(jī)構(gòu)清晰顯示開(kāi)關(guān)狀態(tài)；3）電弧隔離技術(shù)降低飛弧風(fēng)險(xiǎn)；4）寬溫度適應(yīng)性（-25℃~+60℃）。產(chǎn)品通過(guò)優(yōu)化電磁系統(tǒng)設(shè)計(jì)，在保持高分?jǐn)嗄芰Φ耐瑫r(shí)降低了能耗，有助于用戶實(shí)現(xiàn)節(jié)能降耗的運(yùn)營(yíng)目標(biāo)。46
英文產(chǎn)品描述
The CDM3-160H/33002 100A moulded case motor protector is designed for three-phase asynchronous motor protection in 380V/415V AC systems. With 160A frame current and adjustable trip current up to 100A, it features thermal-magnetic release mechanism combining instantaneous short-circuit protection (10-12In) and inverse-time overload protection. The compact unit achieves 35kA breaking capacity at 400V with visible contact position indicator.
Key specifications include: 800V rated insulation voltage, 8kV impulse withstand voltage, 20,000 mechanical operations. The 3-pole version measures 75×130×68mm with 0.78kg weight. For 690V systems, it maintains stable performance with optimized trip curve to distinguish between motor starting current and fault current. The N-pole options (Type A/B) provide flexibility for different distribution systems.
Ideal for pumps, fans and compressors, its advantages include modular maintenance design, energy-efficient electromagnetic system and wide temperature tolerance (-25℃~+60℃). The arc chute design effectively contains arc flashes while the rotary handle ensures clear switching status indication. 147
