Four-Pole Circuit Breaker
In this video, I'm going to show you the difference between a tetra circuit breaker (tetrapolar or 4-pole circuit breaker), a three-phase circuit breaker (3-pole circuit breaker or 3-pole circuit breaker), a 3-pole + neutral circuit breaker, a 1-pole + neutral circuit breaker (single-pole + neutral circuit breaker), a 1-pole circuit breaker (single-pole circuit breaker) and a 2-pole circuit breaker (2-pole circuit breaker)
I notice that we mix the switchgear and that's why I decided to make a little video tutorial on circuit breakers!
