Midnight Solar's MNEPV breakers are rated to break the full rated load at the rated voltage repeatedly, without damage. These 2-Pole 300VDC breakers are 1” (25 mm) wide. The terminals can accommodate 14 AWG to 6 AWG cable.
MNEPV breakers are the same as CBI QY breakers except the standard used is inadequate for the solar industry. Always use a properly sized breaker for disconnecting. MidNite Solar breakers have been evaluated by ETL to 300VDC 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 300VDC and in many cases are not suitable for the solar industry. These breakers are listed for 10,000 AIC.
Max. DC voltage (Voc): 300 VDC, 2 Pole
Breaker Torque Value: 20 In-Lbs (2.3NM)
Available sizes, rated current (Amps): MNEPV15-300 MNEPV20-300 MNEPV30-300
All MidNite circuit breakers hold 100% rated current independent of ambient temperature. These 300 Volt DC breakers mounts on a DIN rail, therefore they can be used with Outback, Midnite Solar and other combiner boxes.
