This module detects and indicates an insulation drop on a load circuit (TN-S or TT systems).
Operation is identical to that of a Vigi module, but without circuit-breaker tripping.
Indication by a red LED in front.
An auxiliary contact may be installed for remote insulation-drop indications.
When insulation drops below a minimum, user-set threshold, the LED goes on and
the auxiliary contact switches. The fault indication cannot be cancelled except by
pressing the manual reset button.
**The module is installed directly on the downstream circuit-breaker terminals.
** Degree of protection IP40, IK04.
** Double insulation of the front face.
** Settings: 100 - 200 - 500 - 1000 mA.
** Accuracy: -50 +0 %.
** Time delay following insulation drop: 5 to 10 seconds.
** AC-system voltage: 200 to 440 V AC.
