Frequently Asked Questions

What is the advantage of a non-polarized DC breaker?+

Non-polarized breakers can handle current flow in either direction. This eliminates the risk of damage or fire caused by reverse-polarity wiring, which is a common concern with traditional polarized DC breakers in solar applications.

Can I use this breaker for branch circuit protection?+

Yes, these MidNite Solar breakers are UL 489A listed, specifically rated for branch circuit protection in communications and solar power electrical systems.

Will this breaker fit a standard DIN rail?+

Yes, it features a 13mm (0.5 inch) width designed specifically for standard 35mm DIN rail mounting, commonly used in solar combiner boxes and DC disconnect enclosures.

Is this a direct replacement for the older polarized MNEPV models?+

Yes, the MNEPV-150-1PNP series is the designated non-polarized replacement for older polarized MNEPV breakers. They provide the same form factor with enhanced safety through non-polarized operation.
