Siemens 3RT2017-2AK62 Power Contactor, 12A, 5.5kW, 110V/120V AC, S00 Original Brand New

Overview

The Siemens 3RT2017-2AK62 is a high-performance, 3-pole SIRIUS 3RT20 Power Contactor designed for switching motors up to 5.5 kW at 400 V (AC-3e/AC-3). This compact, size S00 device features a reliable 110 V AC (50 Hz) / 120 V AC (60 Hz) coil and a single integrated Normally Closed (1 NC) auxiliary contact. Utilizing spring-loaded terminal technology, it ensures fast, secure, and vibration-proof wiring, making it an ideal choice for efficient control panel assembly in industrial automation systems.

Key Benefit

• Fast & Secure Wiring: The innovative spring-loaded terminals drastically reduce wiring time and maintenance by providing a reliable, vibration-proof connection, eliminating the need for periodic screw retightening.
• Space-Saving Design: As part of the SIRIUS modular system, the compact size S00 footprint allows for high-density control panel configurations.
• Global Standard Compliance: IEC and UL/CSA approval ensure the contactor is suitable for worldwide use and integration into globally exported machinery (IE3/IE4 ready).
• High Reliability: Exceptional contact reliability and long mechanical service life (up to 30 million operating cycles) minimize downtime and increase system longevity.

Function / Application

The 3RT2017-2AK62 power contactor is primarily used for switching 3-phase AC motors and resistive loads. Its main applications include:

1. Motor Control: Switching small to medium-sized motors in machinery, pumps, fans, and conveyor systems.
2. Industrial Automation: Serving as a crucial switching element in control circuits, combined with motor protection circuit breakers (MPCBs) and overload relays (like the SIRIUS 3RU2).
3. Resistance Heating: Switching and controlling heating elements in industrial processes.
4. Integrated Control: The auxiliary contact (1 NC) provides feedback or interlocking for complex control sequences within a PLC or control system.
