Siemens SIRIUS 3RT2016-2MB41-0KT0 Power Contactor, 9A, 4kW, 24V DC, 3-Pole, Spring-Loaded Terminal, Size S00 Original Brand New

Overview: Siemens SIRIUS 3RT2016-2MB41-0KT0 Power Contactor

The Siemens 3RT2016-2MB41-0KT0 is a high-performance 3-pole power contactor from the globally recognized SIRIUS 3RT20 series, designed for reliably switching motors and other loads up to $4\text{ kW}$ at $400\text{ V}$. Featuring a modern $24\text{ V DC}$ coil with a wide operating range ($\text{0.85-1.85}\times \text{Uc}$), this contactor ensures stable and efficient operation even under fluctuating voltage conditions.

This compact Size S00 contactor utilizes spring-loaded terminals for fast, vibration-proof, and maintenance-free wiring, making installation quick and secure. It includes an integrated 1 NO (Normally Open) auxiliary contact for signaling or interlocks. The design of this specific model is not expandable with additional auxiliary switch blocks, offering a streamlined solution for defined applications.

Benefit

• Reliable & Durable: Part of the trusted Siemens SIRIUS modular system, ensuring high contact reliability and a long mechanical service life (typically $30,000,000$ switching cycles).
• Fast, Secure Wiring: Spring-loaded terminals significantly reduce wiring time, eliminate the need for re-tightening, and provide a secure, vibration-resistant connection.
• Space-Saving Design: The compact Size S00 construction saves valuable space in control panels and electrical cabinets.
• Wide Voltage Tolerance: The $24\text{ V DC}$ coil’s extended operating range is highly effective against voltage drops or spikes, enhancing operational stability.
• Integrated Monitoring: Includes an internal $1\text{ NO}$ auxiliary contact for direct feedback and control circuit integration.

Function & Application

The 3RT2016-2MB41-0KT0 contactor’s primary function is to act as a remote-controlled electrical switch, closing and opening the main power circuit to control a load. It is mainly used for:

1. Switching 3-phase AC motors (up to $4\text{ kW}$) in applications such as pumps, fans, conveyors, and machine tools.
2. Switching resistive loads (AC-1 operation) like heaters or lighting circuits.
3. Integration into industrial automation systems, motor starter combinations (DOL, Reversing), and control panels.
