【English Version】
The CDM1-250L/3320 125A Molded Case Circuit Breaker is a protective device designed for low-voltage distribution systems, providing reliable overcurrent and short-circuit protection. Its modular construction combines electrical safety with operational convenience and maintenance flexibility.
The housing utilizes high-strength engineering plastics with excellent insulation properties and mechanical durability. The silver alloy contact system works in conjunction with an optimized arc-extinguishing chamber design to enhance breaking capacity. With a rated current of 125A, this three-pole device is suitable for protecting medium-small power distribution lines in three-phase AC systems. The spring-operated mechanism enables quick manual switching, complemented by clear ON/OFF position indicators.
Electrical performance features include stable thermal-magnetic trip characteristics that provide graded protection based on load current variations. Instantaneous short-circuit protection activates within 20 milliseconds, effectively limiting fault current impact. The device operates reliably across 380V/690V AC systems and demonstrates strong environmental adaptability within -25℃ to +70℃ temperature range.
This product finds application in industrial switchboards, commercial building distribution systems, and power control cabinets, offering protection for motors, transformers, and distribution lines. Its compact dimensions allow easy DIN rail mounting, with protective terminal covers supporting multiple wiring configurations. The transparent inspection window facilitates contact status monitoring, with maintenance intervals recommended according to operational environment conditions.
