Model: Siemens SIRIUS magnet coil type 3RT1924-5AG21.
Electrical: 110 V AC, 50/60 Hz control voltage, screw terminal connections, suitable for size S0 contactors.
Compatibility: Replacement coil for Siemens contactors 3RT1023, 3RT1024, 3RT1025 and 3RT1026 in motor control applications.
Notes: Phased‑out Siemens part; current successor is a SIRIUS 3RT2 series coil, so this is useful for maintaining older installations.
New, never installed; coil and hardware remain in the original Siemens box.
Box shows light storage marks, but the coil assembly is clean with no visible signs of use.
Ideal as a spare part for existing SIRIUS S0 contactors using 110 V AC coils.
