By:Nader Updated:May 15,2020 17:52PM

Description

The NDM3L series of molded case residual current action protectors (hereinafter referred to as protectors) apply to infrequent switching of circuits with the AC 50Hz, the rated working voltage of AC 400V and rated working current of 630A as well as infrequent motor starting. With the overload, short circuit and undervoltage protection functions, the protector can protect lines and power equipment from damage. Meanwhile, they can deal with the personal safety, fire hazards and other potential risks caused due to long-term ground faults that can't be detected with the overcurrent protection function.
 

Features

◆ The protector can adopt packaged accessories for quick installation, thus responding to the user's requirements, without adjustment.
◆ The protector can adopt packaged accessories for quick installation, thus responding to the user's requirements, without adjustment.
◆ Adjustable on the site: 3-gear residual current, 3-gear delay time, to be adjusted by users according to the onsite demands.
◆ Leakage tripping indication function: In case of leakage tripping for the product, the leakage tripping indication button will pop up.
◆ Extremely strong work capacity in case of the working voltage failure: When the phase voltage is reduced to 50V, the residual current protection function can still be realized reliably.
 

Certification

NDM3L series of molded case residual current action protector has obtained China Compulsory Certification (CCC) for products.
