Abstract (en)
1. A thermal relay comprising : a first case (2") in which are disposed current monitoring bi-metal strips (3 to 5) adapted to communicate their movements to a link (9) and a second removable case (2') associated with the first one so that the link may communicate to a normally closed safety switch (45), placed inside, a work position in which the switch is open, characterized in that this switch (45), a movement transmission device (77) and a thermal compensation device (19) are disposed in said second case (2') having a small width ("q") measured in the direction of movement of the link (9) and having on several faces (80, 61, 64, 110) access windows (85, 84, 83, 109, 116) which are closed by dividing walls (72, 63, 86, 76) belonging to the first case (2").

Relais thermique comprenant un premier boîtier recevant les bilames de surveillance du courant et un second boîtier amovible contenant un interrupteur de sécurité. Des leviers (14, 17, 20, 33, 46) appartenant respectivement à un dispositif de transmission (77), à un dispositif de compensation thermique (19) à un dispositif de passage de point mort (30) et à l'interrupteur de sécurité (45) sont pivotés autour d'axes placés dans un plan médian PP' du second boîtier (2') qui est perpendiculaire à la direction de déplacement d'une réglette (9, 10) placée entre les bilames et le dispositif de transmission. Ca relais thermique de faible volume est avantageusement utilisé en association avec des petits contacteurs.
