Arc flesh - Easergy P3, P5 & Vamp321 documentation/certificate

[Ivan_Puškaš_EC]

Hello everyone,

I would like to address to you in order to get pretender documentation and certificates for Arc flesh protection.

What I would like to get is official certificate or SE document that states what is the time for arc flesh detection for ARC relays. All in order to put it in tender specification. 

For example Vamp 321 2ms arc detection and reacting time, or Easergy P3/P5 2/7ms for integrated arc protection. 

Also if there is some other pretender specification mostly ofor any of these 3 relays P3 P5 and Vamp321(with modules) it would be nice to have ti.

Best regards,

Hi,

Once again.

Can someone from marketing department (or any other department responsible for this issue) check if there is some official document from SE or even better from independent laboratory that states time for ARC protection reaction for P3/P5 and Vamp 321 system?  

Basically certificate that confirms data in the manuals :

Hi Ivan,
First, thanks a lot for making these inquiries about Arc performance and functional test.
IEC standards give criteria about " how to test" and not about protection's performance. That includes Arc protection as well. But in IEC 60947-9-2 ED1 which is under development and would be published later in 2021, the standard describes the ignition & test duration of an arc-fault in the context of an Internal Arc Control Devices(IACD) performance; this defined condition could help to have a rough idea about Arc performance criteria. In standard, the duration of the arc (for stand-alone or multifunction type IACD) is 10ms. If the relay trip <10ms so it passes the test.

Moreover, I’m going to attach the V321 internal Type Test Certificate including the functional test and its performance. Hope it helps. The report covers standard request and also confirm the table you shared.

Regarding P3/P5 I will follow up on the topic and come back to you.
Do not hesitate to contact me if further clarification is required.

Thank you for this clarification.

This can be helpful in pretendering stage of arc flesh solutions for ongoing and future projects.

Please inform us if new documentation described above or some other documentation comes available.

Also for anything you find for now, like V321 internal Type Test Certificate, please attach it in this topic if possible.

Best regards,
