That 24 A figure governs resistive and moderate inductive loads; for filament lamp switching it's rated at 1 500 W, so it handles lighting circuits without derating surprises. The coil accepts 115 V AC or 110 V DC, meaning it works on either a standard AC control transformer or a DC bus — useful when the panel has mixed supplies. The 36 mm width (2 width units) fits standard 35 mm DIN rail enclosures; the 71 mm depth and 64 mm installation depth mean it clears most shallow backboxes without forcing a deeper cabinet. ## Deployment context The SENTRON series is Siemens' standard for building and industrial distribution; the insta contactor variant is sized for switching loads like lighting, small motors, or resistive heaters in commercial and light-industrial panels.","metaTitle":"Siemens 5TT5730-1 SENTRON Insta Contactor, 24 A, 4 NO, 230/4","metaDescription":"Siemens 5TT5730-1 SENTRON insta contactor, 24 A rated, 4 NO contacts, 115 V AC / 110 V DC coil, IP20, 36 mm wide.
