Overview
Siemens 3MT8040-1AB03 is a compact and durable AC-3 contactor from the SIRIUS series, designed for the reliable control of three-phase motors in industrial applications. With a rated operational current of 40 A and the capability to switch motors up to 18.5 kW at 400 V AC, this contactor is ideal for medium-duty systems such as pumps, compressors, fans, and conveyors. It is housed in the Size S2 frame, offering a compact footprint for space-efficient control panel designs. The contactor features a 3-pole configuration with screw terminals for secure and easy wiring. The suffix “AB03” indicates that the device includes a 24 V AC control coil, a common voltage level in control systems, and it also comes equipped with one normally open (NO) and one normally closed (NC) auxiliary contact, providing flexible options for signaling and interlocking functions.
