The ABN 103C 3-Pole Thermal-Magnetic Moulded Case Circuit Breaker (MCCB) is a cost-effective distribution protection switch from Shouke (SKN)’s ABN series. It serves as a perfect replacement for equivalent imported/traditional brand products, delivering high-performance overload and short-circuit protection for industrial, commercial, and residential power distribution systems. Designed for 380/440V low-voltage distribution scenarios with a breaking capacity of 18kA, it meets the safety protection requirements of standard distribution circuits.

2. Core Specifications & Performance Highlights

🔧 Key Functions

1. Dual Protection, Reliable Safety
   • Thermal Trip (Bimetallic Strip): Provides time-delay overload protection, automatically tripping with a delay during long-term line overload to prevent equipment burnout.
   • Magnetic Trip (Solenoid Coil): Delivers instantaneous short-circuit protection, tripping in milliseconds when a short circuit occurs to quickly cut off fault current and safeguard the distribution system.
2. Manual Operation & Isolation Function

   Equipped with a front-panel operating handle for manual circuit on/off control. The breaker forms a clear visible break when tripped, doubling as a circuit isolator to meet maintenance safety requirements.

3. High Compatibility, Perfect Replacement

   Dimensions and mounting hole positions are fully compatible with mainstream equivalent MCCBs (e.g., LS ABN103C), enabling direct replacement without cabinet modification, reducing renovation costs and construction difficulty.

4. Cost-Effective Selection, Efficiency Boost

   Offers far lower pricing than imported brands with equivalent performance, ideal for cost-sensitive distribution projects, significantly cutting procurement costs without compromising protection performance.
