150A Three-Pole Industrial Circuit Breaker for Electrical Circuit Protection
The NF-150A circuit breaker ensures safe protection and switching of high-power electrical circuits in industrial environments, workshops, and installations with powerful electrical appliances. With a 150A capacity and 600V insulation, it is directly mounted in electrical panels for controlling motors, pumps, industrial machinery, and main supply lines.
What you get with this product
- Secure protection for high-power circuits — supports loads up to 150A without overheating
- Quick screw mounting — attaches directly to the electrical panel, connections via solid cable terminals
- Clear manual ON-OFF switching — visible lever with distinct positions for quick circuit control
- Integrated reset button — quick reset after overload trip, without disassembly
- Robust flame-retardant construction — impact-resistant ABS casing and copper contacts for durability
- Three-phase compatibility — works with voltages from 220V to 600V AC, applicable in various installations
How it works and how to install it
The circuit breaker is mounted on a DIN rail or fixed with screws to the electrical panel. The power and load cables are connected to the upper and lower terminals by tightening with a screw. The lever allows manual opening or closing of the circuit, and in case of overload, the circuit breaker trips automatically and is reset by pressing the red reset button on the front. Suitable for main control in industrial installations with high-power consumers.
Frequently asked questions
What voltage does this circuit breaker operate at?
It operates at voltages between 220V and 600V AC, being compatible with both single-phase and three-phase industrial installations.
How difficult is it to mount in the electrical panel?
Installation is simple by screw fixing and connecting cables to terminals. Any authorized electrician installs it in 15-20 minutes.
What happens if an overload occurs?
The circuit breaker trips automatically and interrupts the circuit. After resolving the issue, it is reset by pressing the red reset button.
