英文介紹
The DZ20L-250T/4300 molded case leakage circuit breaker is designed for AC power distribution systems, featuring a transparent housing that allows visual inspection of internal components. With a rated current of 250A and leakage protection threshold of 500mA, it responds within 0.1 seconds to isolate faulty circuits, enhancing electrical safety.
Key features include overload, short-circuit, and earth leakage protection. The transparent cover provides clear visibility of contact status and switching position, simplifying maintenance. Its robust construction ensures reliable performance under high fault currents, making it suitable for industrial, commercial, and residential applications.
Typical applications include main distribution panels, motor control centers, and building switchboards, particularly in environments demanding stringent leakage protection, such as data centers, medical facilities, and manufacturing plants. The compact design and easy installation further add to its versatility. 611
