Siemens SIRIUS 3RT2038-3AF04 Power Contactor, 80A, 37kW, 400V, Size S2, 110V AC Coil, Spring-Loaded/Screw Terminal Original Brand New

High-Performance Siemens SIRIUS 3RT2038-3AF04 Power Contactor

The Siemens 3RT2038-3AF04 is a robust, 3-pole power contactor from the highly reliable SIRIUS 3RT2 series, engineered for switching motors and other electrical loads. With an operational current of 80 A ($\text{AC-3e/AC-3}$) and a maximum operational power of 37 kW at 400 V, this contactor is built for demanding industrial environments.

It features a control voltage of 110 V AC (50 Hz) and an integrated, removable auxiliary switch block with 2 NO + 2 NC contacts for maximum system flexibility. The main power circuit uses secure screw terminals, while the control and auxiliary circuits utilize time-saving, vibration-proof spring-loaded terminals. Its compact Size S2 design makes it an ideal choice for efficient panel construction.
