The KACO relay RY is mainly used in deviceswhich require a 2 pole mains isolation accord-ing to DIN VDE 0106 part 101.As stipulated in e.g. DIN VDE 0631, 14 the RYrelay has an air gap and a creepage distance of>8 mm and an operational surge voltage of >4 kV. The contact gap is >3 mm. The standard version contains silver cadmium oxide contacts. Tungsten is also available as a possible contact material for special applications. The relay isproduced with two NO contacts or with one NOand one NC contact. On request, we offer a ver- sion with two NO contacts but without mains isolation. Because of...
