The 24 A figure is the continuous current the main contacts can carry in AC duty — sized for resistive or moderate inductive loads like lighting banks, small heaters, or fan coils. The 3 normally-open and 1 normally-closed contact arrangement gives you three independent switched legs plus one auxiliary feedback path, which is the standard layout for controlling a three-phase load and reporting its state back to a PLC or building management system. The 24 V AC/DC coil means the contactor pulls in on either supply type, which simplifies panel wiring when the control voltage is shared with other 24 V devices. The 2 MW width (36 mm) fits two standard 18 mm DIN-rail module slots, so it occupies the same footprint as a typical 2-pole MCB — useful when you're packing contactors into a crowded enclosure. IP20 protection means it's suitable for installation inside a closed control cabinet or junction box where no water or dust ingress is expected. The 1500 W filament lamp switching capacity tells you the contacts are rated for the high inrush of incandescent lighting — a common spec for building-automation contactors that switch large lamp banks. The 64 mm installation depth leaves clearance behind the DIN rail for wiring — typical for a contactor of this class. The 71 mm overall depth includes the coil terminals and arc chambers; ensure the enclosure door or gland plate doesn't compress the wiring space below that dimension.","metaTitle":"Siemens 5TT5731-2 SENTRON Insta Contactor, 24 A, 3 NO + 1 NC","metaDescription":"Siemens 5TT5731-2 SENTRON Insta contactor, 24 A rated, 3 NO + 1 NC contacts, 24 V AC/DC coil, IP20, 2 MW.
