The CDM3-63F/3340 25A DC24V molded case circuit breaker is a circuit protection device designed for DC low-voltage distribution systems, suitable for electrical environments with rated current of 25A and DC voltage of 24V. Featuring modular structure design, it integrates overload protection and short-circuit protection functions to effectively enhance the safety and stability of power distribution systems.
In terms of core performance, the breaker is equipped with a quick trip mechanism capable of detecting line abnormalities and interrupting fault current within milliseconds, thereby reducing equipment damage risks. The contact system employs silver alloy material with excellent conductivity and arc resistance. Combined with double-breakpoint interruption design, it significantly extends product service life. The housing utilizes high-strength engineering plastic with flame-retardant and impact-resistant properties, adaptable to wide temperature environments from -25℃ to +70℃.
This product finds applications in new energy equipment, rail transit auxiliary power systems, DC lighting systems, and industrial automation control cabinets. Its compact design supports rail-mounted installation for multi-circuit integration in limited spaces. The operation handle provides clear "ON/OFF" status indication and allows remote manual reset, simplifying maintenance procedures.
Safety features include built-in arc-extinguishing chamber to suppress arc diffusion during interruption, reducing operational risks. The terminal block adopts anti-loosening pressure spring design to ensure connection stability under high-current conditions. Additionally, the product provides two-pole isolation protection to meet specific electrical isolation requirements of DC systems.
For maintenance, regular inspection of terminal tightness is recommended along with surface dust removal and ventilation maintenance. If handle jamming occurs, professional troubleshooting is advised before resetting. Compatible with standard DC distribution cabinet installation specifications, the product supports both vertical and horizontal mounting orientations.
