This Acti9 iTL is Schneider Electric's modular and reliable impulse relay. It has 2 normally open contacts, is rated 16 amperes and operates with 230 - 240VAC or 110VDC impulse control signal. This product benefits from Schneider Electric expertise with more than 40 years developing modular devices for all type of applications. It has a longer service life thanks to its high limitation and fast closing. This product is compliant with IEC 669-1, IEC 669-2-2, IEC 60529, has IP20 on opening, IP40 in an enclosure and is DIN rail mountable. Ideal for lighting control applications, for example control of a light with more than 3 switches in a living room or a corridor. . Ideal for lighting control applications, for example control of a light with more than 3 switches in a living room or a corridor. High rated current capability in a small package: control many lighting circuits without increasing the size of your panel. Up to 200000 cycles endurance: even with 100 switching cycles per day, the contactor will last more than 5 years. Can switch even with very short 50 ms impulses: your lighting circuit will switch on, no matter how briefly the user pushes the light button.
