English Version:
The CDM1-125L/3300 125A Molded Case Circuit Breaker is a circuit protection device specifically designed for low-voltage distribution systems, suitable for power distribution scenarios with rated currents up to 125A. Featuring modular construction, it integrates overload protection and short-circuit protection functions to ensure safe and stable operation of electrical circuits.
The core structure employs high-strength insulated housing with precision electromagnetic trip mechanism and bimetal thermal protection system. Silver-based alloy contacts combined with optimized arc chute design enable rapid fault current interruption. The three-stage energy storage spring mechanism ensures reliable switching operations, achieving mechanical durability exceeding 10,000 cycles. Adjustable tripping characteristics allow customized protection parameter settings.
Designed for 50Hz AC systems with rated operational voltage up to 400V, this breaker is widely applicable in industrial plants, commercial buildings, and public facility distribution panels. Typical applications include motor protection, main circuit protection, and critical equipment power supply protection. Multiple installation options support both vertical and horizontal mounting configurations, with rail-mounted design facilitating quick installation.
Product advantages manifest in three aspects: Firstly, the compact structure saves 30% space compared to similar products. Secondly, 25kA breaking capacity ensures swift short-circuit interruption. Thirdly, the flame-retardant transparent cover with observation window enables operational status monitoring. Optional accessories include auxiliary contacts and shunt trip units for enhanced control flexibility.
Operating recommendations suggest usage within ambient temperatures of -5℃ to +40℃ and altitudes below 2000 meters. Regular inspection of terminal tightness and ventilation maintenance are advised. After tripping events, complete fault elimination and contact reset verification are essential before re-energization.
Through optimized thermal management and material selection, the CDM1-125L/3300 125A delivers reliable protection while maintaining installation efficiency and operational economy. Its enhanced heat dissipation design contributes to extended service life under continuous operation conditions.
