LV circuit breaker test with primary injection case

[StevenPerrault]

At P&V Panels, we invested in a primary injection case. As of today, we are able to inject your LV circuit breaker at very high currents. The movie below shows a test of a 6300A Siemens circuit breaker but of course we can also test Schneider Electric circuit breakers!
See for yourself.

Great Investment @StevenPerrault 

What is your need? Is it for commissioning or for maintenance ?

What is the maximum value of curent you can inject ?

Hello @StevenPerrault 

Thank you for sharing this video, I have a quick question : what exactly is a primary injection test ? What is the purpose ? 

Thank you for your answer!

Hello @M_Duca ,

For information about Primary injection test on LV circuit breakers, you can refer to this article:

I hope this will help you.

Thank you @L_Valentin ,

Very instructive. 🤔

Hello @Gregoire_Brun ,

We use it for commissioning and probably (in the future) also for maintenance. We can inject 13kA for about 5 seconds.

I recently read an article on how to test a circuit breaker with a multimeter. I think knowing how to test your circuit breaker will allow you to save money by finding out what’s wrong with your breaker, even before calling an electrician.

Hello @jameslandry ,

This is applicable, but there are alot of standards and safety concerns regarding elektricity and the electrical installation.
This is not something to mess around with. Measuring something with a multimeter however is very different with having to test an high amperage / big circuit breaker like an compact with many settings and/or options to consider.

There is nowadays however alot of digitalisation and you can view errors and gain maintenance notices by circuit breakers when they need it or even before they need it! For instance; (https://www.se.com/ww/en/product-range/62980-ecostruxure-power-commission/#overview)

I recommend to always let an schooled electrical/service/maintenance engineer do this.
