Siemens 3TF42 10-0AC2 023110-CC1-1 Industrial Relay

Siemens 3TF42 10-0AC2 is a three‑pole motor contactor designed to switch and control 3‑phase motors in industrial control panels. The coil is rated for 110 VAC (coil code 10-0AC2), enabling energization of the contactor via standard control voltages. This model accommodates typical line voltages and corresponding motor horsepower: 3 hp at 230 VAC, 10 hp at 460 VAC, and 15 hp at 575 VAC, making it suitable for a range of motor sizes in automation and process equipment. The unit carries the catalog reference 023110-CC1-1 and uses screw terminals for secure connections on L1/L2/L3 and T1/T2/T3, facilitating straightforward integration into existing motor control circuits. In practical panel installations, it serves as a robust switch for conveyors, pumps, fans, and other heavy‑duty machines where reliable 3‑pole switching is required. The 3TF42 family is designed to integrate with Siemens overload relays and other SIRIUS control components for scalable, modular motor control in industrial environments.
