    AI Overview
    The Siemens SIRIUS 3RT2028-100 (specifically within the 3RT2028-1A series) represents robust 3-pole contactors designed for industrial motor control, not soft starters. They offer up to 38 A operational current (AC-3/400V), 18.5 kW power rating, and utilize screw terminals, often used in load feeders up to 25 HP at 460V. 
    Key Features and Specifications (3RT2028-1A): 
    • Contactor Type: 3-pole SIRIUS 3RT2 contactor.
    • Performance: 38 A rating at AC-3 (up to 400 V), ideal for 18.5 kW motors.
    • Connection Type: Screw terminals.
    • Size: S0 size, compact design suitable for tight spaces.
    • Operating Conditions: Suitable for various climates, touch-safe per DIN VDE 0106 Part 100.
    • Auxiliary Contacts: Basic units can be extended with auxiliary switch blocks, with 2 NO + 2 NC options. 
    Typical Applications: 
    • Switching 3-phase asynchronous motors.
    • High-frequency switching applications.
    • Industrial, heavy-duty environments (AC-3, AC-4). 
    For soft starting functionality, Siemens recommends the SIRIUS 3RW30/3RW40 soft starters, which provide controlled acceleration and reduction of voltage spikes, as opposed to the direct-on-line switching provided by the 3RT2028 contactor.

    What is a 3 phase soft starter?
    The three phase soft starter is designed to significantly reduce start-up current and noise in many three phase motors. The start-up current can be reduced by approximately 40% without compromising the start-up torque required.
