16.6 Residual current protection function
16.6.1

General

EMAX circuit-breakers can be equipped with a toroid fitted at the rear of the CB (at a max distance of ten meters) so as to ensure protection against

residual current ground faults.

In particular, the electronic releases which can ensure this function are as follows:

- PR122/P LSIRc,

- PR122/P LSIG fitted with a PR120/V module

- PR123/P LSIG.

The residual current protection function is available only in the event of a dedicated rating plug which carries sensitivity ranges and non-trip times

characterizing this function.

Available Settings

400

630

800

1250

2000

3200

Two toroidal sizes are available: the small toroid can be installed on E1 and E2 three-pole sizes, the medium toroid can be installed on E1 and E2

four-pole sizes and on E3 three-pole sizes.

The PR122/P LSIRc unit provides all PR122/P LSI functions but with one addition: protection against residual current faults.

Using PR122/P LSIG with additional PR120/V module, the protection against residual current is added to a unit having the characteristics of a PR122/

P LSI and all additional ones described for the PR120/V module, see par. 15.1.

With a PR123/P LSIG unit, the Rc protection function replaces the external G function (Gext); however, G function is retained.

The following table shows the available settings:

The following table shows protection thresholds and times that can be set:

Thresholds Non-trip times

0.06s

0.10s

0.20s

10A

0.30s

20A

0.40s

30A

0.50s

0.80s

(tar)

The Rc protection is activated only when a rating plug dedicated to Rc function is available, and after correctly performing

the unit installation procedure.

This protection cannot be disabled.
