MidNite Solar Circuit Breaker 100A 150VDC 2 Pole DIN Mount - MNEPV100

The MidNite Solar MNEPV100 is a high-amperage polarized din rail mount circuit breaker designed for robust overcurrent protection in photovoltaic systems. Rated for 150VDC with a 10,000 AIC interrupt capacity, this wide-body breaker (1 inch / 26mm) is engineered to break the full rated load at the rated voltage repeatedly with NO DAMAGE. It is ideal for large battery bank disconnects, high-power inverter inputs, main system disconnects, and heavy-duty DC load protection.

Key Features & Benefits

High 100A Current Capacity: Perfect for large battery bank disconnects, high-power inverter DC inputs (e.g., 6-8kW+ inverters), main PV array combiners, and heavy-duty DC load panels.

150VDC Rating: Suitable for 12V, 24V, and 48V battery-based systems as well as medium-voltage PV arrays, offering flexibility across a range of applications.

Heavy-Duty 1-Inch (26mm) Width: Wider body than standard 13mm breakers, designed to handle higher currents and accommodate larger wire sizes up to 2 AWG.

Repeated Load Breaking Capability: Built to break the full rated load at rated voltage repeatedly with no damage, unlike standard breakers not designed for solar applications.

100% Rated Current in MidNite Enclosures: Can be used at full rated current (100A) without derating when mounted in a MidNite Solar enclosure.

10,000 AIC Interrupt Capacity: High interrupting capacity provides robust protection against fault currents.

Polarized for DC Safety: Engineered specifically for DC applications with proper polarity orientation, ensuring safe and reliable interruption of DC current.

ETL Listed for US & Canada: When used in MidNite Solar enclosures, this breaker maintains its North American listings and safety certifications.

Indoor Installation (Type 1): Rated for indoor use in dry locations, suitable for load centers, combiners, and equipment rooms.

Technical Specifications

Important Technical Notes

MidNite vs. CBI Breakers: MNEPV breakers are the same as CBI QY breakers, except the standard used for CBI is inadequate for the solar industry. MidNite breakers have been evaluated by ETL to 150VDC and are listed for US and Canada. Breakers ordered under the CBI part numbering system will not be listed for 150VDC and in many cases are not suitable for solar applications.

100% Rated Current: All MidNite circuit breakers can be used at 100% rated current when mounted in a MidNite enclosure.
