Siemens SIRIUS 3RT2016-1AD01 Power Contactor, 9A, 4kW, 42V AC Coil, 3-Pole, Size S00 Original Brand New

Product Overview: Siemens 3RT2016-1AD01 SIRIUS Power Contactor

The Siemens 3RT2016-1AD01 is a high-performance, 3-pole power contactor from the SIRIUS 3RT2 modular control system, specifically designed for switching motors and other resistive loads. As a part of the next-generation SIRIUS modular system, this contactor offers a compact design, high contact reliability, and extensive compatibility with other components (like thermal overload relays and auxiliary switches) for fast, flexible, and space-saving control cabinet construction.

This particular model is rated for a maximum operational current of 9 A (AC-3e/AC-3) for motor switching at 400 V, equating to 4 kW of power. It features a reliable 42 V AC, 50/60 Hz control coil and includes 1 Normally Open (NO) integrated auxiliary contact. The unit utilizes robust screw terminals for easy and secure wiring and belongs to the compact Size S00 classification.

Benefit & Features

• Compact & Space-Saving: Size S00 design allows for high-density packing in control cabinets, making it ideal for applications with limited space.
• High Reliability: Exceptional switching reliability and a long mechanical service life (typically 30,000,000 switching cycles).
• IE3/IE4 Ready: Optimized for switching the latest generation of energy-efficient motors.
• Integrated Auxiliary Contact: The base unit includes 1 NO auxiliary contact, reducing complexity and the need for separate add-on blocks in many applications.
• Flexible Wiring: Features robust screw terminals for main and auxiliary circuits, ensuring a strong and dependable connection.
• Modular System: Fully compatible with the SIRIUS modular system accessories, including overload relays and additional auxiliary switch blocks, for seamless motor starter construction.
• Global Standard: Globally approved (IEC, UL/CSA) and climate-resistant for worldwide use.

Function / Application

The Siemens 3RT2016-1AD01 power contactor is primarily used for:

1. Switching 3-Phase Motors: Ideal for Direct-On-Line (DOL) starting of AC motors up to 4 kW / 9A (at 400V).
2. General Resistive Loads: Switching electric heaters, lighting circuits, and other general AC loads.
3. Integration into Motor Starters: Forming a complete electrical motor starter in combination with a matching SIRIUS 3RV2 thermal or electronic overload relay.
4. Remote Control: Providing reliable remote control switching capability using the 42 V AC control voltage.
