25A MCCB Circuit Breaker for Safe Protection
The NT50 Mini MCCB 25A circuit breaker provides automatic protection against overloads and short circuits in residential and industrial electrical installations. Compact and robust, it mounts quickly on any secure surface, offering immediate control via the ergonomic lever and instant disconnection in case of electrical problems.
What you get with this product
- Automatic overvoltage protection — the breaker instantly trips the circuit in case of overload or short circuit, preventing equipment damage
- Compact dimensions of 70x32x53mm — easily integrates into small electrical panels or tight spaces, without taking up valuable room
- Copper contacts with platinum-plated tip — ensures excellent conductivity and long-term wear resistance
- Fire-retardant Bakelite casing — withstands high temperatures and prevents fire risk in case of malfunction
- Simple 2-screw mounting — no special tools or advanced knowledge required, quick installation on any solid surface
- Versatile for multiple applications — works perfectly in 220V household installations, solar panels, industrial machinery, or other AC circuits
How it works and how to install it
The NT50 MCCB breaker constantly monitors the electrical current flowing through the circuit. When it detects an overload exceeding 25A or a short circuit, the internal mechanism automatically trips the circuit, interrupting the power supply to protect connected equipment. Reactivation is done manually by returning the lever to the ON position.
Installation only requires connecting the 4 contacts: 2 for power input, 2 for output to consumers. Fixing to the surface is done with 2 screws positioned on the sides. Compatible with standard cables for 25A current, no additional adapters are needed.
Frequently asked questions
Does it work at both 110V and 220V?
Yes, the breaker is compatible with both voltages, AC110V and AC220V, making it ideal for standard household installations in Romania (220V).
What happens if I exceed 25A on the circuit?
The circuit breaker automatically and immediately trips to protect the installation. After rectifying the problem, you reactivate it manually by raising the lever.
Can I use this breaker for solar panels?
Yes, it is compatible with solar installations operating at 110V or 220V AC and currents up to 25A, providing a safe protection solution.
