400A 10.4Ohm Neutral Grounding Resistor

Neutral Grounding Resistor systems are essential components in power systems, serving to safeguard electrical equipment by limiting ground fault currents to safe levels. By inserting these resistors between the neutral and ground, potential damage from faults is mitigated, ensuring the system’s stability and protecting against electrical hazards. Known interchangeably as Neutral Earthing Resistors (NGRs) and Earth Fault Protection Resistors, these devices play a crucial role in maintaining the integrity and safety of power distribution networks.

● ZENITHSUN Neutral Grounding Resistors (NGRs) are designed to provide added safety to industrial distribution systems by limiting ground fault current to reasonable levels.
● Installation environment:
Installation Height: ≤1500 meters ASL,
Ambient Temp: -10℃ to +50℃ ;
Relative Humidiry: ≤85%;
Atmospheric Pressure: 86~106kPa.
The installion place of load bank should be dry and ventilative. There is no flammable, explosive and corrosive materials around load bank. Due to resistors are heaters, the temperature of the load bank will be higher and higher, there should be leave some space around the load bank, avoid the influence of outside heat source.
● Please note custom designs may be available. Please speak to a member of our sales team for more information.
