Siemens SIRIUS 3RT2024-1AF00 Power Contactor | 12A, 5.5kW, 400V, 110V AC Coil, Size S0, 3-Pole, 1 NO + 1 NC Aux, Screw Terminal Original Brand New

Overview: SIRIUS 3RT2024-1AF00 Power Contactor

The Siemens 3RT2024-1AF00 is a high-performance, 3-pole power contactor from the globally recognized SIRIUS 3RT20 series, engineered for the reliable switching of motors and resistive loads in industrial control systems. This Size S0 contactor is rated for $12\text{ A}$ (AC-3e/AC-3) and a maximum operational power of $5.5\text{ kW}$ at $400\text{ V}$.

Featuring a standard $110\text{ V AC},50\text{ Hz}$ control supply voltage, the $3\text{RT}2024$–$1\text{AF}00$ comes equipped with one integrated normally open (1 NO) and one normally closed (1 NC) auxiliary contact, simplifying wiring for control and signaling functions. The robust screw terminals ensure a secure and reliable connection for both the main and auxiliary circuits.

As a core component of the modular SIRIUS system, this contactor offers a compact design, exceptional contact reliability, and full compatibility with a wide range of accessories like overload relays and auxiliary switch blocks, making it an ideal choice for building efficient and compliant motor starters and load feeders.
