MNEPV breakers are the same as CBI QY breakers except the UL standard used by UL is inadequate for the solar industry. MidNite breakers have been evaluated by ETL to 300 VDC and are listed for US and Canada.
All of the UL listings still apply. Breakers ordered under the CBI part numbering system will not be listed for 150 VDC and in many cases are not suitable for the solar industry.
All MidNite circuit breakers hold 100% rated current independent of ambient temperature.
