Whether you're building a new solar system, adding battery storage, or upgrading your AC circuits, the MNEAC series of DIN rail-mounted breakers are a reliable, NEC-compliant option known for consistent performance and rugged durability.

What Is the MNEAC Breaker?

The MNEAC is a series of DIN rail-mounted AC circuit breakers manufactured by MidNite Solar, specifically designed for 120VAC applications.

These breakers are available in a wide range of amperages—starting from 5A and going up to 60A—to suit various load requirements in solar PV and backup power systems.

What sets the MNEAC apart is its consistent performance, 100% continuous duty rating, and the ability to handle full load interruptions repeatedly without damage.

These breakers are essential in ensuring your system operates safely and efficiently, especially in high-demand environments.

Key Features of MNEAC Breakers

DIN Rail Mounting

The MNEAC breakers are designed exclusively for DIN rail mounting, making them easy to install inside enclosures. This saves time for installers and provides a neat, organized layout.

Wide Amperage Range

Available in various models:

MNEAC 5A to 25A – Rated as Branch Circuit Protection (UL 489A)

MNEAC 30A to 60A – Rated for Supplementary Protection (UL 1077)100% Continuous Duty

All MidNite Solar circuit breakers, including the MNEAC line, are rated for continuous duty. This means they can operate at full rated current without risk of overheating or failure.

Full Load Interruption Capability

These breakers are engineered to break the full rated load at the rated voltage repeatedly without causing damage—a hallmark of quality and long-term reliability.

UL Listed for USA and Canada

All MNEAC breakers meet industry safety standards and carry necessary certifications, ensuring compliance and peace of mind.

Compact Size

With a width of just 0.5 inches (13mm), the MNEAC breakers save space inside control panels, allowing for efficient design even in tight enclosures.

Torque Value

• Breaker Torque Value: 20 in-lbs (2.3 Nm) —ensuring secure and proper terminal connections during installation.

Indoor Use Rated

• Environmental rating: Type 1 (Indoor use only), ideal for protected installation environments like breaker boxes, solar control rooms, and indoor panels.
