Siemens 3RT2017-1AK62 SIRIUS Power Contactor, 12A, 5.5kW, 110V AC Coil, Size S00 Original Brand New

Overview: Siemens 3RT2017-1AK62 SIRIUS 3RT2 Power Contactor

The Siemens 3RT2017-1AK62 is a high-performance, 3-pole power contactor from the SIRIUS 3RT2 series, designed for reliably switching motors in industrial control applications. This Size S00 contactor is rated for switching $12\text{ A}$ (AC-3) and is capable of handling motor loads up to $5.5\text{ kW}$ at $400\text{ V}$.

Featuring a versatile 110 V AC ($50\text{ Hz}$) / 120 V AC ($60\text{ Hz}$) control voltage, the $3\text{RT}2017\text{-}1\text{AK}62$ is an essential component for motor starters and control systems worldwide. Its compact design and integrated 1 NC auxiliary contact minimize space requirements and simplify wiring, while robust screw terminals ensure secure, lasting connections.

Benefit & Key Features

• Optimized Performance: Meets the requirements of AC-3e (high-efficiency motors) and standard AC-3 switching applications.
• Reliable Operation: High switching reliability for industrial motors up to $5.5\text{ kW}$.
• Global Compatibility: Dual-frequency ($50\text{ Hz}/\text{60 Hz}$) 110/120 V AC coil is suitable for diverse global electrical standards.
• Space-Saving Design: Compact Size S00 form factor is ideal for control cabinets with limited space.
• Integrated Monitoring: Comes standard with $1\text{ NC}$ (Normally Closed) auxiliary contact for feedback and interlocking circuits.
• Easy Installation: Features proven screw terminal connection technology for quick and robust wiring.

Function

The $3\text{RT}2017\text{-}1\text{AK}62$ functions as an electromechanical switch that is controlled by the low-power $110/120\text{ V AC}$ coil. When the coil is energized, it closes the three main power contacts, allowing current to flow to a connected three-phase motor. The integrated $1\text{ NC}$ auxiliary contact changes its state (opens) simultaneously, providing a reliable signal for control circuits, such as interlocking or status indication.
