Siemens 3RT2016-1AF01-1AA0 SIRIUS Power Contactor 9A, 4kW, 110V AC Original Brand New

Overview: Siemens 3RT2016-1AF01-1AA0 SIRIUS 3RT2 Power Contactor

The Siemens 3RT2016-1AF01-1AA0 is a high-performance, robust power contactor from the globally recognized SIRIUS 3RT2 series, specifically engineered for switching motors and other resistive loads. Designed for industrial control applications, this 3-pole contactor is rated for $9\text{ A}$ (AC-3e/AC-3) and $4\text{ kW}$ at $400\text{ V}$, providing reliable operation for small to medium-sized motor control systems.

It features a control supply voltage of $110\text{ V AC}$ (at $50/60\text{ Hz}$), includes one integrated normally open ($\text{1 NO}$) auxiliary contact, and utilizes secure screw terminals for easy wiring. Its compact $\text{Size S00}$ footprint and upright mounting position make it ideal for space-saving installations in control panels. As an active Siemens product, the 3RT2016-1AF01-1AA0 ensures current compliance with modern safety and efficiency standards.

Benefits & Features

• Optimal Performance: Rated for $9\text{ A}$ AC-3e/AC-3 and $4\text{ kW}$ at $400\text{ V}$, perfect for robust motor switching applications.
• Space-Saving Design: Compact $\text{Size S00}$ footprint is ideal for high-density panel installations.
• High Reliability: Part of the trusted Siemens SIRIUS 3RT2 line, known for long mechanical service life (up to $30\text{ million}$ operating cycles).
• Simplified Wiring: Equipped with reliable screw terminals for secure and straightforward connection.
• Integrated Monitoring: Comes standard with $1\text{ NO}$ auxiliary contact for feedback or interlocking circuits.
• Global Standard Compliance: Suitable for worldwide use, adhering to IEC and EN standards.

Function

The Siemens 3RT2016-1AF01-1AA0 Power Contactor is primarily used for switching AC motors and resistive loads. When the $110\text{ V AC}$ control voltage is applied to the coil, the contactor closes its three main power contacts, allowing current to flow to the motor. The integrated auxiliary contact provides a signal to the control system indicating the contactor’s status. Its $\text{AC-3e/AC-3}$ rating signifies its suitability for squirrel-cage motors:

• AC-3: Starting, and switching off motors during running.
• AC-3e: Enhanced efficiency rating conforming to new IEC standards.

Application

This contactor is an essential component in:

• Direct-on-line (DOL) motor starters
• Control panels for pumps, fans, and compressors
• Heating, Ventilation, and Air Conditioning (HVAC) systems
• Conveyor systems and material handling equipment
• General industrial motor control
