MidNite Solar MNDC-GFP80 Ground Fault Circuit Breaker 80A

MidNite Solar MNDC-GFP80 Ground Fault Circuit Breaker. 80 Amp 150VDC Panel Mount DC Ground Fault Protector. NRTL listed breaker assembly.

MidNite's breakers are rated to break the full rated load at the rated voltage repeatedly, with NO DAMAGE. Always use a properly sized breaker for disconnecting. All MidNite circuit breakers hold 100% rated current independent of ambient temperature. NEC2008 requires DC-GFP’s on all solar installations.

FAQ

• Does the MNDC-GFP80 disconnect the battery ground when tripped?
  Yes, the MNDC-GFP80 disconnects the bond between the battery negative and ground negative when tripped.
• Why does this circuit breaker say "Max Volts 125V," but the breaker is advertised as 150VDC?
  Carling Technologies is the manufacturer for MidNite Solar's MNDC-GFP80 circuit breakers and they are normally rated to 125V, however, because the MNDC-GFP80 circuit breakers are built to MidNite Solar's specifications, MidNite Solar rates the MNDC-GFP80 breaker to 150VDC when used in a MidNite Solar combiner, MidNite Solar E-Panels, or the MidNite Solar MNBIGBABY Enclosure.
• Does the GFP breaker need to match my string voltage the same as a DC breaker?
  Yes, the GFP breaker must match the string voltage the same as a DC breaker, however, the GFP breaker is not allowed as a disconnect and will not provide overcurrent protection.
• Can I have two breakers on the same circuit, such as a DC breaker and a GFP breaker?
  Yes, you can have two breakers on the same circuit. The DC breaker can act as a disconnect and will provide overcurrent protection, whereas the GFP breaker will provide ground-fault protection.
