Note: Branch circuit rated 489AMidNite 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.
MNEPV breakers are the same as CBI QY breakers except the standard used is inadequate for the solar industry. MidNite breakers have been evaluated by ETL to 150VDC and are listed for US and Canada. All of the NRTL listings still apply. Breakers ordered under the CBI part numbering system will not be listed for 150VDC and in many cases are not suitable for the solar industry.
All MidNite circuit breakers can be used at 100% rated current when mounted in a MidNite enclosure. Breaker Torque Value: 20 In-Lbs (2.3NM)
