The CDM3-100S/3310 Molded Case Circuit Breaker is a high-performance circuit protection device specifically developed for low-voltage distribution systems. Designed for 50Hz/60Hz alternating current applications with a rated operational voltage of 400V, this product adopts modular design principles to ensure essential protection functions while maintaining ease of installation and maintenance, making it suitable for various scenarios including industrial control systems, building power distribution, and equipment protection.
With a rated current of 100A, the breaker s main body is molded from high-strength engineering plastics, providing excellent mechanical durability and insulation properties. The three-pole design with 3310 configuration enables effective overload and short-circuit protection for three-phase circuits. Its energy-storing operating mechanism ensures reliable switching actions, while specially treated contact systems minimize contact resistance for long-term operational stability.
The integrated thermal-magnetic trip mechanism combines bimetal elements with electromagnetic coils to promptly detect abnormal current conditions. During overload or short-circuit situations, the device automatically interrupts the circuit within predetermined time limits to mitigate equipment damage risks. The arc-extinguishing chamber incorporates composite splitter plates and gas ventilation channels, significantly improving arc-quenching efficiency for safer operation.
Featuring compact dimensions (specific dimensions can be added), the breaker supports standard rail mounting and integrates seamlessly with mainstream switchboard layouts. The terminal block employs anti-loosening design, accommodating conductors up to 25mm². External indicators clearly display contact positions and trip status, facilitating quick operational assessments by maintenance personnel. Rigorous temperature-rise tests and mechanical endurance verifications confirm stable electrical performance under normal service conditions.
Typical applications include: power distribution control for industrial production lines, commercial building electrical systems, and public infrastructure power supply networks. Professional technicians are recommended to conduct periodic functional inspections and adjust protection parameters according to actual load characteristics to optimize product performance.
