MNDC-GFP100 

Ground Fault Protector

 

100 amp 150VDC panel mount Dual DC ground fault protector (NRTL listed breaker assy) 
 
All MidNite circuit breakers can be used at 100% rated current when mounted in a MidNite enclosure. 

All MidNite circuit breakers hold 100% rated current independent of ambient temperature. 

 
The MNDC-GFP100  can be used in the following ways. 
1 pv array breaking pv - and + using the 1 amp pole as the trip source  
1 pv array breaking pv – and + using the classic to shunt trip the device  
2 pv arrays breaking just the + using the 1 amp pole as a trip source  
2 pv arrays breaking just the + using the classic to shunt trip the device
