Siemens 3RT2015-1AH02 Power Contactor, 7A, 48V AC, S00 Original Brand New

Overview

The Siemens 3RT2015-1AH02 SIRIUS Power Contactor is a high-performance, compact, and reliable switching device designed for controlling motors and other electrical loads. Part of the SIRIUS modular system, this 3-pole contactor is rated for $7\text{ A (AC-3e/AC-3)}$ and $3\text{ kW}/400\text{ V}$. It features a $48\text{ V AC}/50/60\text{ Hz}$ control coil, an integrated Normally Closed ($1\text{ NC}$) auxiliary contact, and secure screw terminals for easy and reliable wiring. Its compact Size $\text{S00}$ makes it ideal for space-saving installations in control cabinets and industrial applications.
