CDM3-100S/4300B 50A Molded Case Circuit Breaker Introduction
The CDM3-100S/4300B 50A molded case circuit breaker is designed for low-voltage distribution system protection, suitable for AC power networks with 50Hz/60Hz frequency and rated operational voltage up to 400V. This device integrates overload and short-circuit protection functions through its modular design concept, providing reliable circuit protection for various electrical installations.
Constructed with high-strength insulated housing, the breaker incorporates precision electromagnetic trip mechanism and thermal bimetal components for rapid response to abnormal currents. The silver alloy contacts combined with optimized arc chute design enhance breaking capacity while minimizing arc duration. The spring-operated mechanism ensures quick manual switching with clear ON/OFF position indication.
Designed for 50A rated current applications, this model is widely used in industrial control cabinets, building distribution boxes and equipment terminal protection. Its three-stage protection characteristic provides flexible coordination with different load types, effectively reducing maloperation risks. The compact dimensions allow vertical or horizontal installation in space-constrained environments, maintaining reliable performance within -5℃ to +40℃ temperature range and altitudes below 2000 meters.
Safety features include multi-layer insulation barriers and transparent status indicators for operational visibility. Plug-in terminal design simplifies wiring processes, while integrated isolation barriers prevent foreign object intrusion. The modular construction ensures compatibility with standard electrical components, facilitating efficient system integration and maintenance procedures.
