This is the 0/1-automatic variant, meaning it can be wired for either momentary or maintained switching depending on the control circuit design. The 20 A operational current at AC rated value is the continuous thermal current (Ith) for the main contacts — it handles resistive and moderate inductive loads up to that level. For incandescent lamp loads, the switching capacity is 1,000 W, which covers most single-lighting-circuit applications in residential or light commercial panels. The 24 V AC control coil is standard for building-management systems; verify your control transformer supplies AC, not DC, because the coil impedance and dropout characteristics differ. Depth is 71 mm, height 90 mm — fits standard distribution boards and sub-distribution panels. Supplementary devices (auxiliary contact blocks, shunt trips, etc.) can be added on the side or top via the product extension interface.","metaTitle":"Siemens 5TT5801-8 SENTRON Insta Contactor, 20 A, 24 V AC","metaDescription":"Siemens 5TT5801-8 SENTRON Insta contactor, 1 NO + 1 NC, 20 A at 230 V AC, 24 V AC coil.
