Resistors

















 

neutral grounding resistors

Mosebach Neutral Grounding Resistors are designed to be used in Industrial Power Systems for added protection against ground fault currents. In the event of a ground fault, the fault current is limited to a safe value by means of Mosebach's WeldlessWeave™ resistors. Designed and tested in accordance with IEEE Standard 32-1972.

ENCLOSURE DESCRIPTION:
The Neutral Grounding Resistor will be placed in outdoor rated NEMA 3R, heavyduty, aluminized steel enclosure with provisions for easy lifting and maneuvering (fork lift or crane).

RESISTIVE LOAD ELEMENTS:
Our WeldlessWeave™ resistors are made of stainless steel and used for this application. WeldlessWeave™ technology utilizes a continuous ribbon to eliminate all welds. By eliminating welds, hot spots are eliminated. To reduce the operating temperature, no thru bolts are used, and a parallel element system reduces the watt density. Finally, our resistors are designed to withstand vibration, and breakable parts are not used. All this results in the maximum operating life of our resistors.

RATING: 10 seconds with a temperature rise of 760° C

MOUNTING: Intended for permanent outdoor installation

CUSTOMER CONNECTIONS: Bus-bars, accessed through the bottom of the enclosure

OPTIONS:
 • Stainless steel enclosure
 • Aluminum enclosure
 • Painted enclosure
 • Current transformer
 • Bushing connections
 • Connections on side of enclosure
 • Connections on top of enclosure
