English Introduction
The CDM1-250L/3340 225A DC24V molded case circuit breaker is designed for DC power distribution systems, featuring a rated current of 225A and operational voltage of DC24V. With thermal-magnetic trip mechanism, it provides reliable overload and short-circuit protection, achieving 35kA breaking capacity. The compact housing contains an advanced arc quenching system that minimizes arc distance. Suitable for industrial applications including renewable energy systems and motor control centers, it supports horizontal/vertical mounting with 20,000 mechanical durability cycles. The modular design allows flexible integration of auxiliary contacts and shunt releases.156
Key advantages include vibration resistance, adjustable protection settings, and visible contact position indicators. The copper alloy contacts reduce energy loss while maintaining stable performance under frequent switching conditions. Its triple protection mechanism (thermal/instantaneous/mechanical) ensures safety in DC microgrids, charging piles, and traction power systems. The product complies with international design norms for plastic-enclosed breakers, offering easy maintenance without disassembling entire panels.61115
