15A Mini MCCB Circuit Breaker for Safe Electrical Protection
The NT50 Mini MCCB 15A circuit breaker provides automatic protection against surges and overloads in household, solar, or industrial electrical installations. Compact and robust, it installs quickly on any surface and operates reliably at 110V AC or 220V AC, with a maximum amperage of 15A.
What you get with this product
- Automatic overload protection — the breaker instantly trips the circuit, preventing damage to electrical equipment and the risk of fire
- Flexible installation without an electrical panel — compact dimensions 70x32x53mm and screw mounting, ideal for confined spaces or mobile applications
- Copper contacts with platinum — maximum resistance to electric arc and wear, for thousands of connection cycles without loss of performance
- Compatible with solar systems and batteries — works perfectly in DC and AC circuits, protecting inverters and charge controllers
- Fire-retardant Bakelite casing — material resistant to high temperatures and shocks, compliant with international safety standards IEC 60898-1
- Visible control lever — clear ON/OFF indicator for quick circuit status check, even in low light conditions
How it works and how to install it
The breaker automatically detects current increases above 15A and interrupts the circuit to prevent cable overheating. Installation takes less than 10 minutes: fix the casing with 2 screws on a stable surface, connect the input and output cables to the 4 contacts, then test the lever operation. It works on the standard 220V AC electrical grid or low voltage 110V AC installations.
Frequently asked questions
Can it be used for solar installations with photovoltaic panels?
Yes, the breaker is compatible with DC and AC solar systems, protecting circuits from inverters, charge controllers, and batteries against overloads.
How often should it be replaced if it trips frequently?
If it trips repeatedly, the problem is usually with the connected loads, not the breaker. Check the equipment's consumption — the product withstands thousands of normal switching cycles.
Can I mount it outdoors or in wet environments?
No, the casing does not have IP protection and is designed for indoor use or in suitable protective enclosures against humidity.
