This curve is used to define the protection (fuses). - 2 -Itsm répétitif est donné pour des surcharges de courant Attention : la répétition de ces surcharges de courant diminue la durée de vie du relais. 2 - Repetitive Itsm is given for inrush current. In normal operation, this curve musn't be exceeded. Caution, frequent over load currents will decrease the life expectancy of the SSR. - → 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. → 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. **® celduc** ~~**www.celduc.com**~~ **r e l a i s** **5, Rue Ampère BP30004 42290 SORBIERS - FRANCE E-mail : celduc-relais@celduc.com 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.

Nous donnons dans nos spécifications le courant en AC-51 (charge résistive). Pour les autres charges, il faut surveiller les surcharges en courant à la fermeture et les surtensions éventuelles à l'ouverture. - AC-55b: Lampes à incandescence : Courants d'appel généralement de 10 fois le courant nominal durant quelques 10ms . - AC-55a: Lampes à décharge. Ces charges ont souvent des surcourants importants à la fermeture et des surtensions à l'ouverture (capacités). Nous conseillons d'utiliser des relais 400VAC sur réseau 230VAC. - AC-58: Moteurs monophasés . Ces charges ont souvent des surcourants importants à la fermeture et des surtensions à l'ouverture (capacités). Nous conseillons d'utiliser des relais 400VAC sur réseau 230VAC et d'adapter le courant du relais au courant de démarrage. - > SKA products are designed for most types of loads. We give in our data-sheet the AC-51 current value corresponding to resistive loads. For other loads, check the inrush current at turn ON and possible overvoltages at turn OFF: - AC-55b: Incandescent lamps : Inrush current is generally 10 times In during few 10ms. - AC-55a: Electric discharge lamp : These loads often have overcurrent at turn ON and overvoltage at turn OFF, so we advise to use 400VAC SSR on 230VAC mains. - AC-58: One pole motors. These loads often have overcurrent at turn ON and overvoltage at turn OFF, so we advise to use 400VAC SSR on 230VAC mains and to adapt the SSR current to the starting current of the motor. ## **Protection / Protection :** - > La protection d'un relais statique contre les court-circuits de la charge peut être faite par fusibles rapides avec des I[2] t = 1/2 I[2] t du relais . - Pour plus de détails nous consulter - > To protect a SSR against a short-circuit of the load , use a fuse with a I[2] t value = 1/2 I[2] t value specified page 2. - For more details consult us. ## **CEM / EMC :** − > Immunité : Nous spécifions dans nos notices le niveau d'immunité de nos produits selon les normes essentielles pour ce type de produit, c'est à dire IEC/ EN61000-4-4 & IEC/ EN61000-4-5.

En effet, les relais statiques sont des dispositifs complexes qui doivent être interconnectés avec d'autres materiels (charges, cables, etc) pour former un système. Etant donné que les autres materiels ou interconnexions ne sont pas de la responsabilité de **celduc[®]** , il est de la responsabilité du réalisateur du système de s'assurer que les systèmes contenant des relais statiques satisfont aux prescriptions de toutes les règles et règlements applicables au niveau des systèmes. Consulter **celduc[®]** qui peut vous conseiller ou réaliser des essais dans son laboratoire sur votre application. - > Emission: **celduc[®]** SSRs are mainly designed in compliance with standards for class A equipment (Industry). - Use of this product in domestic environments may cause radio interference. In this case the user may be required to employ additionnal devices to reduce noise. SSRs are complex devices that must be interconnected with other equipment (loads, cables, etc.) to form a system. Because the other equipment or the interconnections may not be under the control of **celduc[®]** , it shall be the responsability of the system integrator to ensure that systems containing SSRs comply with the requirement of any rules and regulations applicable at the system level. Consult **celduc[®]** for advices.
