NM5NELE series residual current action circuit breaker

Function and use

Chint NM5NELE series residual current action circuit breakers are suitable for AC 50/60Hz, rated voltage AC415V and below, and rated current 10A to 800A circuits. Its main function is to provide indirect contact protection against fatal personal electric shock, to provide protection against electrical fires caused by ground fault current, such as insulation damage, and to provide protection against overload, short circuit and under-voltage of the line, and can also be used for infrequent switching of lines.

Detailed description

Advantages/core functions:
01 Excellent performance
With AC type/A type leakage action protection characteristics

Can provide additional protection for DC pulsating leakage situations, such as charging piles, medical equipment, precision electronic equipment, etc.

Leakage current/delay time is adjustable in four levels, providing customers with a wider adjustment range and reducing replacement costs caused by capacity expansion
02 Flexible and easy to use
The entire series of products can achieve free top/bottom cable entry

Industry-leading miniaturized design of accessories, 4 types of accessories can be installed at the same time, meeting a variety of extended functional requirements
03 Easy to use
The accessories realize box-type modular installation, the accessory frame is streamlined, easy to maintain and replace, and reduces the inventory of spare parts/spare parts
