The DZ15-100/3901 50A Molded Case Circuit Breaker is a circuit protection device specifically designed for low-voltage distribution systems. Suitable for AC 50Hz power environments with rated operational voltage up to 380V, this product adopts modular structural design to provide reliable overcurrent and short-circuit protection for building power distribution, industrial equipment, and residential electrical systems.
This product demonstrates three core technical characteristics: The compact three-dimensional housing structure optimizes space utilization while maintaining protective performance. The high-strength engineering plastic enclosure exhibits excellent insulation properties and mechanical durability, with internal contact system constructed from silver alloy material to ensure stable conductivity and anti-welding capability. Secondly, the precision electromagnetic trip unit can interrupt fault currents within milliseconds when overload or short-circuit occurs, effectively preventing equipment damage. The three-stage arc extinguishing system with metal splitter plates significantly enhances breaking capacity. Additionally, the ergonomic operating mechanism features clear handle action and visible status indication window, facilitating quick identification of device status by maintenance personnel.
Applicable to multiple scenarios including building distribution cabinet main switch protection, motor control circuits, commercial lighting systems, and residential power distribution. The optimized thermal dissipation design supports operational temperature range from -25℃ to +70℃, with IP40 protection rating suitable for standard indoor installations. Compatible with 35mm standard DIN rail mounting, the product allows both vertical and horizontal installation orientations. The dual-securing terminal structure effectively prevents conductor loosening, ensuring long-term connection reliability.
