Siemens 3RT1024-1A..4 AC Three-Phase Contactor

Siemens Sirius 3RT1024-1A..4 is a 3-pole AC-3 power contactor in the Sirius 3RT10 family, designed to start and stop 3‑phase motors in industrial control panels. It uses a 230 VAC coil and features screw-terminal connections in size S0 with upright mounting. The unit is rated for 12 A AC-3 and corresponds to about 5.5 kW (400 V) or 7.5 HP, with variant data noting 3 HP at 230 V and 7.5 HP at 460 V for the same line, reflecting its suitability across common motor sizes. This makes it well suited for drives such as pumps, fans, and conveyors in panel-based motor control applications, and it can be extended with auxiliary contact blocks for signaling or interlocking as needed.
