CDM1-125L/33002 20A Molded Case Circuit Breaker Product Description
The CDM1-125L/33002 20A molded case circuit breaker is a circuit protection device designed for low-voltage distribution systems, providing reliable overload and short-circuit protection for industrial, commercial, and residential applications. With a rated operational current of 20A, this product is suitable for AC 50Hz power distribution networks with rated operational voltage up to 400V.
Featuring a modular design, the breaker incorporates a high-strength engineering plastic enclosure that delivers excellent insulation performance and mechanical durability. The internal contact system utilizes high-conductivity alloy materials combined with an optimized arc-extinguishing structure, ensuring effective fault current interruption. The three-position spring energy storage mechanism guarantees stable switching operations. A distinct tripping indicator window allows quick identification of operational status.
The 33002 model provides dual protection functions: overload time-delay protection and short-circuit instantaneous protection, with adjustable parameters to meet practical requirements. Supporting both horizontal and vertical mounting orientations, the product features anti-loosening terminal design compatible with conductors up to 35mm² cross-sectional area. The integrated isolation function ensures reliable circuit disconnection in the open position.
This circuit breaker is suitable for application in distribution panels, motor control cabinets, and lighting systems, offering protection for line terminal equipment. Users are advised to select appropriate specifications based on actual load characteristics and conduct regular operational status checks. All parameter adjustments should be performed with power supply disconnected to ensure operational safety.
