There are no normally-open contacts on this variant. The 20 A AC operational current is the continuous carry rating under AC load. That covers most lighting, resistive heater, and small motor contactor duties within the 250 V AC line-to-line or line-to-neutral envelope. The 1000 W incandescent lamp switching capacity gives a quick check for lighting-circuit replacement: if the lamp bank pulls under 1 kW, this contactor handles the inrush without welding the contacts. Power loss runs 1.7 W per pole in hot operating state. That is low enough that a single unit in a closed panel won't need derating, but the installation note explicitly calls for spacers between adjacent devices to ensure heat dissipation — so don't pack them tight without the recommended air gap. It belongs inside a panel or enclosure with a higher-rated door — not on a washdown line or outdoors without a cover.","metaTitle":"Siemens 5TT5802-2 SENTRON Insta Contactor, 24 VAC Coil, 20 A","metaDescription":"Siemens 5TT5802-2 SENTRON Insta contactor. 24 VAC coil, 20 A rated current, 2 NC contacts, 250 VAC, IP20.
