Industrial Electrical Protection for 150A Three-Phase Networks
The NF-150A three-phase power circuit breaker provides industrial and commercial electrical installations with protection against overloads and short circuits. It is a professional solution for electrical panels requiring maximum safety and compliance with European standards, with quick DIN rail mounting.
What you get with this product
- Automatic overload and short-circuit protection — instant circuit interruption in case of an electrical incident
- 150A amperage — sufficient capacity for industrial equipment and high-consumption commercial installations
- CE European standard certification — compliance with safety directives for low-voltage electrical equipment
- Robust construction from thermosetting plastic — resistance to high temperatures and wear in continuous operation
- Simple 35mm DIN rail mounting — quick installation in electrical panels without special tools
- Clear status visualization — handle position immediately indicates whether the circuit is connected or disconnected
How it works and how to install it
The circuit breaker is mounted on a DIN rail in the main electrical panel, connecting in series on the three phases of the network. The internal bimetallic mechanism detects prolonged overloads, and the electromagnetic trip unit reacts instantly to short circuits. In case of a fault, the three-phase circuit breaker automatically disconnects all three phases, protecting the circuit and connected equipment. Reconnection is done manually, after the problem is resolved.
Frequently Asked Questions
Can I use this circuit breaker for standard residential installations?
The 150A amperage is oversized for most homes. It is intended for industrial, commercial installations, or for the protection of secondary electrical panels with high consumption.
Is it compatible with all types of electrical panels?
Yes, it mounts on the standard 35mm DIN rail, present in most modern industrial and commercial panels.
What should I do if the circuit breaker trips frequently?
Repeated tripping indicates a real problem: either a constant overload in the network or a defect in connected equipment. It requires verification by an authorized electrician to identify the cause.
