應(yīng)用場景
CDM1-400L/3310 315A廣泛應(yīng)用于工業(yè)廠房、商業(yè)建筑、基礎(chǔ)設(shè)施等領(lǐng)域的低壓配電系統(tǒng)，特別適用于電動機保護（400A以下負載）、變壓器出線保護及主干線路保護。其模塊化設(shè)計便于維護，插入式接線結(jié)構(gòu)簡化安裝流程，可適配GGD柜等常見配電柜型。典型應(yīng)用包括風(fēng)機、水泵、傳送帶等設(shè)備的電源控制與故障隔離。221
Product Overview
The molded case circuit breaker CDM1-400L/3310 315A is a high-performance electrical device designed for power distribution systems and motor protection, suitable for circuits with AC 50Hz/60Hz and rated operational voltage up to 400V. Featuring thermal-magnetic trip mechanism with shunt release (3310 type), it provides rapid response to overloads and short circuits, ensuring reliable circuit interruption. With 400A frame size and 315A rated current, it meets medium-to-high load requirements while maintaining excellent breaking capacity. 19
Key Features
The breaker utilizes a robust plastic housing offering insulation and corrosion resistance. Its compact structure supports front/rear mounting options. The integrated thermal-magnetic unit combines bimetallic strip for overload protection and electromagnetic coil for instantaneous short-circuit protection. Manual operation handle (optional motorized mechanism available) ensures easy control, with arc chutes minimizing arc distance. Additional accessories like auxiliary contacts and undervoltage releases can be equipped for functional expansion. The grey-white exterior blends well with industrial environments. 919
Applications
Ideal for low-voltage distribution systems in factories, commercial buildings and infrastructure projects, this model excels in motor protection (below 400A), transformer feeder protection and main circuit protection. Modular design simplifies maintenance, while plug-in terminals streamline installation in GGD cabinets. Typical applications include power control and fault isolation for motors driving fans, pumps, conveyors, etc. 221
