Product Introduction of CDM1-100L/3310 Molded Case Circuit Breaker
The CDM1-100L/3310 molded case circuit breaker is a professional electrical protection device developed for power system requirements. Designed for AC 50Hz networks with rated operational voltage up to 400V or DC circuits up to 220V, this 100A-rated unit with DC24V control capability provides reliable overload and short-circuit protection for electrical lines.
Featuring a modular design philosophy, the breaker incorporates a high-strength thermoplastic enclosure housing precision electromagnetic trip mechanisms and bimetal thermal protection components. The three-pole (3310) configuration enables multi-circuit synchronization control, while silver-alloy composite moving contacts combined with optimized arc-extinguishing chambers enhance electrical breaking efficiency. The spring-operated energy storage mechanism supports both manual operation and remote electrical control, with a three-position mechanical indicator (Connected/Disconnected/Tripped) for clear operational status visualization.
This device is suitable for industrial distribution cabinets, building electrical systems, renewable energy installations, and rail transit applications, providing circuit protection for motors, transformers, and lighting systems. Its compact form factor allows space-efficient installation via DIN rail mounting or bolt fixation. Environmental durability testing confirms stable operation within -5℃ to +40℃ temperature range and ≤90% relative humidity.
Safety features include dust-resistant enclosed construction meeting industrial protection standards. Double-break contact separation technology ensures rapid and reliable circuit interruption. The transparent protective cover facilitates visual inspection of internal components. Regular maintenance should include terminal connection checks, mechanism lubrication, and ensuring proper ventilation for optimal thermal management.
