NF-50A Automatic Circuit Breaker without Fuses, 220V, Full Protection
The NF-50A circuit breaker is the professional solution for protecting electrical circuits up to 50A, without the need for traditional fuses. Ideal for industrial and residential electrical panels, it offers quick disconnection in case of overload or short circuit. Designed for fast installation and long-term use in intense conditions.
What you get with this product
- Automatic overload and short-circuit protection, no fuse replacement needed
- Quick installation using a standard DIN rail mounting system
- Visible manual ON/OFF switch for complete circuit control
- Resistant to varying temperatures and voltages, suitable for industrial environments
- Robust ABS and metal construction, durable over time
- Long-term savings — a single breaker replaces dozens of consumable fuses
How it works and how to install it
The circuit breaker is mounted on the DIN rail in the electrical panel using a metal spring clamping system. Power cables are connected to the upper terminals and output cables to the lower terminals, according to the diagram marked on the casing. In case of an overload exceeding 50A or a short circuit, the device automatically trips, interrupting the current. To restart, manually operate the lever on the panel.
Frequently asked questions
What is the difference compared to a traditional fuse?
The automatic circuit breaker is manually reset after tripping, without needing to be replaced. It requires no consumable parts and provides constant, unlimited protection.
Can it be used for residential or only industrial installations?
It can be used in both environments. It is ideal for general panels in homes, workshops, commercial spaces, and industrial installations where loads up to 50A are handled.
What happens if there are voltage variations?
The circuit breaker is designed for stable operation at varying voltages and automatic tripping only in case of overload or short circuit, protecting connected equipment.
