d LED
Rouge: préalarme. Fixe avec I≥0,9 Ir,
clignotante avec I≥1,05 Ir.
Verte: fonctionnement régulier
déclencheur.
Clignotante rouge/verte > 90°C
e Bouton-poussoir test mécanique.

AUTOPROTECTION THERMIQUE
Température interne
Une sonde capable de donner un signal en
cas de température anormale à l’intérieur du
déclencheur (> 90°C).
En cas du température excessive,
les deux leds clignoteront simultanément.
N.B.: Réglages protégés par couverture
transparente pouvant être plombée.

(four-pole only).
b Long-term protection setting.
c Short-term protection setting.
d LED
Red: pre-alarm. Comes on when I≥0,9
Ir, flashing when I≥1,05 Ir.
Green: overcurrent release normal
operation.
Flashing red/green > 90°C
e Mechanical test button.
f Only for service.
THERMAL PROTECTION
Internal temperature
An internal sensor system measures the
operating internal over temperature of the
releases (> 90°C).
The condition of maximal temperature is
indicated by flashing of the two leds.
N.B.: Settings are protected by a
transparent sealable cover.
