30A Automatic Circuit Breaker for Industrial and Domestic Electrical Protection
The NF-30A circuit breaker provides automatic protection against overloads and short circuits in three-phase and single-phase electrical installations. Designed for residential and commercial applications, this MCCB type breaker guarantees the safety of electrical circuits up to 30A and 600V AC, with intuitive manual ON/OFF control.
What you get with this product
- Instant automatic protection — trips in 0.1 seconds on overload, preventing equipment damage and fire risk
- Clear manual ON/OFF control — immediate visualization of circuit status, ideal for daily operation without confusion
- Universal compatibility 220-600V AC — suitable for single-phase and three-phase installations, adapted to Romanian electrical standards
- Robust ABS and metal construction — impact and wear resistance, reliable operation in industrial conditions and high temperatures
- Standard installation in electrical panel — quick mounting on DIN rail or with screws, no modifications to the existing panel
- Push-to-Trip button for testing — periodically check protection functionality, according to electrical safety standards
How it works and how to install it
The circuit breaker is mounted in the electrical panel on a DIN rail or fixed with screws, connecting the input and output cables to the upper and lower terminals. When the nominal current of 30A is exceeded or in case of a short circuit, the electromagnetic mechanism automatically trips, interrupting the circuit. Resetting is done manually by returning the lever to the ON position after eliminating the cause of the fault. Functionality is periodically tested by pressing the red Push-to-Trip button.
Frequently Asked Questions
Can it protect single-phase 220V circuits or only three-phase?
This circuit breaker works on both single-phase 220V and three-phase installations up to 600V AC, being versatile for domestic and industrial use.
What happens if it exceeds 30A for a short time several times?
With repeated overloads below 50A, the circuit breaker does not trip immediately but accumulates heat; at over 50A or short circuit, the protection intervenes instantly for installation safety.
Can it reset automatically or does it require manual resetting?
Resetting is exclusively manual by raising the lever to the ON position, thus checking the cause of the fault before restarting.
