For motor loads, you derate to the AC-3 category; the 1 500 W filament lamp load rating gives a practical handle for lighting circuits. The 230 V / 440 V line voltage range covers standard single-phase and three-phase supplies across most industrial and commercial installations. Four NO contacts and zero NC means this contactor is a straight make-only device — it closes all four poles when the coil is energized. If your circuit requires a normally-closed auxiliary for status feedback or a holding circuit, you will need an external auxiliary contact block or a different variant. Insta contactors are the standard building block for switching lighting, heating, and small motor loads in commercial and industrial control panels. The 24 A rating and 4-pole configuration make this one suited for three-phase resistive loads (heaters, ovens) with a spare pole for neutral switching, or for splitting a single-phase load across multiple circuits. The 36 mm width conserves DIN-rail space — two units side by side occupy the same footprint as a standard 72 mm breaker.","metaTitle":"Siemens 5TT5730-2 SENTRON Insta Contactor, 4NO, 24 A, 230/44","metaDescription":"Siemens 5TT5730-2 SENTRON Insta contactor, 4 NO contacts, 24 A rated current, 230/440 V AC coil 24 V DC, IP20, 36 mm wide.
