**1 -Itsm non répétitif**sans tension réappliquée est|| **1 -Itsm non répétitif** sans tension réappliquée est donné pour la détermination des protections. 1 - _No repetitive Itsm is given without voltage reapplied . This curve is used to define the protection (fuses)._ **2 -Itsm répétitif** 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. 2 - _Repetitive Itsm is given for inrush current with initial Tj = 70°C. In normal operation , this curve musn't be exceeded._ _Be careful, the repetition of the surge current decreases the life expectancy of the SSR._ **celduc ®** ~~**www.celduc.com**~~ **r e l a i s 5, Rue Ampère BP30004 42290 SORBIERS - FRANCE E-mail : celduc-relais@celduc.com** ~~OO~~ **Fax +33 (0) 4 77 53 85 51 Service Commercial France Tél. : +33 (0) 4 77 53 90 20 Sales Dept.For Europe Tel. : +33 (0) 4 77 53 90 21 Sales Dept.
