Frequently Asked Questions

Can this breaker be used for 3-phase commercial solar systems?+
Yes, the triple-pole design and 277VAC rating make it ideal for 3-phase systems or applications where separate disconnects are required for multiple conductors in a single circuit, particularly in 480/277V environments.
What is the difference between a UL 1077 and a UL 489 breaker?+
This breaker is UL 1077 listed as a supplementary protector, meaning it is intended for use within equipment where branch circuit protection is already provided or not required. It is not a primary branch circuit breaker.
Is this breaker rated for continuous duty at its full nameplate capacity?+
Yes, all MidNite Solar circuit breakers are rated for 100% continuous duty when mounted inside a MidNite enclosure, ensuring they won't nuisance trip at full load.
Can I use the MNEAC-3P for DC solar strings?+
No, this specific model is rated for 277VAC only. For DC applications, you should use MidNite Solar's MNEPV or MNEDC series breakers which are specifically rated for high-voltage DC.
