## **Courants de surcharges / Overload currents** 

1 - No repetitive Itsm is given without voltage reapplied . This curve is used to define the protection (fuses). 

- 1 - Itsm non répétitif (1) sans tension réappliquée est donné pour la détermination des protections. 

- 2 - Repetitive Itsm is given for inrush current with initial Tj = 70°C. In normal operation, this curve musn't be exceeded. 

- Caution, frequent over load currents will decrease the life expectancy of the SSR.

- 2 -Itsm répétitif (2) est donné pour des surcharges de courant (Tj initiale=70°C). Attention : la répétition de ces surcharges de ~~courant diminue la durée de vie du relais.~~ 

→ Warning !  semiconductor relays don't provide any galvanic insulation between the load and the mains. Always use in conjunction with an adapted circuit breaker with insulation feature  or a similar device in order to  ensure a reliable insulation in the event of wrong function and when the relay must be insulated from the mains (maintenance ; if not used for a long duration ...). 

It is important that the solid state relay is subject to correct installation, maintenance and use conforming to its intended regulations and standards, to the supplier's instructions and to accepted rules of art. 

→ Attention ! les relais à semi-conducteurs ne procurent pas d'isolation galvanique entre le réseau et la charge. Ils doivent être utilisés associés à un disjoncteur avec propriété de sectionnement ou similaire, afin d'assurer un sectionnement fiable en amont de la ligne dans l'hypothèse d'une défaillance et pour tous les cas où le relais doit être isolé du réseau (maintenance; non utilisation sur une longue durée...). Sous réserve d'installation, d'entretien et d'utilisation conformes à sa destination, à la réglementation, aux normes en vigueur, aux instructions du constructeur et aux règles de l'art.
