Electronic Intelligent Circuit Breaker 125A 3P

What are the differences between electronic intelligent circuit breakers and ordinary circuit breakers?

The Electronic Intelligent Circuit Breaker 125A 3P can not only reliably break in case of overload or short circuit, but also issue circuit fault warnings through its built-in high-precision sensors and electronic tripping unit.

• Full parameter digital setting: Through the local panel or software, all protection parameters such as overload long delay (L), short circuit short delay (S), instantaneous (I), and ground fault (G) can be precisely set, achieving perfect selective coordination with upstream and downstream equipment and eliminating over-level tripping.
• Advanced protection functions: Supports phase imbalance protection, under-voltage protection, reverse power protection (applicable to photovoltaic), etc., meeting the special protection requirements of complex systems.
• Real-time data monitoring: Continuously measure and display all electrical parameters including three-phase current, voltage, frequency, power (active power, reactive power, apparent power), power factor, energy (four-quadrant), and total harmonic distortion (THD).
• Operation status diagnosis: Monitor its own opening and closing times, temperature status, and load rate curve to provide a data foundation for predictive maintenance.

FAQ

Q: Compared with the solution of "ordinary electronic circuit breakers" plus "external electricity meters", what are the advantages of smart circuit breakers?

A: Comprehensive advantages in integration, reliability, cost and space. Intelligent circuit breakers integrate measurement, protection and communication into one, avoiding the wiring complexity and fault points of external sensors and instruments. They have better data synchronization, occupy less overall space and have lower total installation and maintenance costs in the long run.
