CDM3-160S/3310 Moulded Case Circuit Breaker is specifically engineered for low-voltage DC distribution systems, designed for circuit protection under rated current 125A and operational voltage DC24V. Featuring modular construction, it provides reliable overload and short-circuit protection to ensure electrical system safety.
The breaker incorporates high-performance tripping mechanism capable of rapid fault current interruption. Its silver-alloy contacts combined with multi-stage arc quenching design maintain stable arc-breaking performance in DC applications. The 3-pole linked mechanism (3310) ensures synchronized phase interruption, eliminating potential hazards from single-phase failure. The housing utilizes high-strength engineering plastics with excellent insulation and impact resistance, achieving IP40 protection level.
With compact dimensions (approx. 90mm×70mm×75mm), the unit supports both DIN rail and fixed mounting options. Oxidation-resistant terminal clamps allow reliable operation in wide temperature range from -25℃ to +70℃. The ergonomic handle integrates dual-color status window for intuitive on/off indication. Rated short-circuit breaking capacity reaches 10kA with mechanical endurance exceeding 10,000 operations, meeting industrial durability requirements.
Typical applications include solar PV systems, EV charging infrastructure, DC distribution panels, and energy storage protection circuits. Optimized EMC design minimizes operational voltage surges affecting sensitive electronics. Specially designed ventilation channels and high-temperature resistant coils ensure stable performance during continuous operation.
