Product Introduction
The CDM1-250L/4300 250A molded case circuit breaker is a high-performance protection device featuring modular design and compact structure. It operates in AC 50Hz-60Hz networks with rated operational voltage up to 690V, providing reliable overload and short-circuit protection for electrical circuits. The thermal-magnetic trip unit ensures precise fault detection and rapid interruption, while the robust plastic housing offers excellent insulation and mechanical durability for industrial applications. 1122
Key Features
With 25kA breaking capacity and short arcing distance, this 4-pole breaker (4300 type) delivers enhanced safety performance. The dual protection mechanism combines bimetal strip for overload protection and electromagnetic release for instant short-circuit response. Clear handle position indicators provide visible isolation status. Flexible front/rear mounting options and accessory slots (including shunt trip and undervoltage release) allow customized configuration. The optimized arc quenching system minimizes voltage transients during operation. 1518
Typical Applications
Ideal for 125A-250A distribution networks in factories, commercial buildings and infrastructure projects. Frequently deployed as main switch for transformer protection or branch circuit protector for motors/lighting systems. Its reliable performance makes it suitable for critical facilities requiring uninterrupted power supply, such as data centers and medical institutions. The product s vibration-resistant design ensures stable operation in demanding environments. 1419
