Resistors – Generator Neutral Grounding Resistor
High quality neutral grounding resistors designed for generator protection with customizable parameters and robust safety features.
What is a Neutral Grounding Resistor?
Neutral Grounding Resistors (NGRs) limit fault currents in generator systems, enhancing safety and protecting equipment by grounding the neutral point. They are customizable for various voltage and fault current requirements.
Core Benefits
- Limits fault currents to safe levels
- Customizable ohmic values based on fault current
- Robust design for indoor and outdoor use
- IP00 to IP65 enclosure options
- Supports natural or forced cooling
