Frequently Asked Questions

What are the classifications of frame circuit breakers (ACBs) based on protection?

Frame circuit breakers (ACBs) can be classified into two main types based on their protection functions: Four section protection frame circuit breakers (LSIG) and Three section protection frame circuit breakers (LSI).

What do the letters L, S, I, and G stand for in ACB protection?

L stands for Overload Long Delay, S stands for Short circuit short delay, I stands for Short circuit instantaneous protection, and G stands for Earth fault protection.

What accessories can be equipped with 400V air circuit breakers?

The 400V air circuit breakers can be equipped with a variety of accessories to enhance performance, including auxiliary contacts, shunt releases, and undervoltage releases.

How does the modular design of the 400V air circuit breaker benefit installation?

The modular design makes installation and maintenance easy, which significantly reduces system downtime and ensures the reliable operation of the electrical system.

What is the difference between LSI and LSIG circuit breakers?

LSI circuit breakers provide three stages of protection (Overload Long Delay, Short circuit short delay, and Short circuit instantaneous), while LSIG circuit breakers include all three stages plus additional Earth fault protection (G).
