Siemens SIRIUS 3RT2015-1JB41 Power Contactor, 7A 3kW 400V, 3-Pole, 24V DC, Size S00 Original Brand New

Overview: SIRIUS 3RT2015-1JB41 DC Power Contactor

The Siemens 3RT2015-1JB41 is a high-performance, compact SIRIUS 3RT2 power contactor designed for switching motors and other resistive loads up to $7A$ or $3kW$ at $400V$. Engineered for modern control systems, this 3-pole contactor features a low-power $24V$ DC coil with an integrated diode for surge suppression, making it perfectly suitable for direct connection to PLC outputs (Programmable Logic Controller).

Part of the flexible SIRIUS modular system, the Size S00 unit ensures high reliability and is an ideal choice for machinery, control panels, and automation applications where space and coil suppression are critical.

Benefit & Features

1. PLC Compatibility: The $24V$ DC coil with a wide operating range and integrated diode is specifically engineered for safe, direct control by sensitive PLC outputs, minimizing control wiring complexity and ensuring fast, reliable switching.
2. Space-Saving Design (Size S00): Its compact dimensions allow for high-density mounting in control cabinets, helping to reduce panel size and cost.
3. High Reliability: Features an integrated surge-suppression diode to protect the coil and the control electronics from switching transients, extending the lifespan of the entire system.
4. Integrated Auxiliary Contact: Comes standard with $1NO$ auxiliary contact for simple signaling or interlocking circuits, eliminating the need for an external add-on block.
5. Robust Connection: Secure and reliable screw terminals are provided for both the main and auxiliary circuits.
6. Worldwide Standards: Part of the globally recognized Siemens SIRIUS system, ensuring compliance with international standards (e.g., IEC, UL/CSA) for global machinery markets.

Function / Application

The SIRIUS 3RT2015-1JB41 functions as an electromechanical switch (contactor) to safely control the flow of electrical power to industrial equipment. It is primarily used for:

• Motor Switching: Direct On-Line (DOL) starting and stopping of 3-phase AC motors up to $3kW$ at $400V$.
• Resistive Loads: Switching of heating elements, lighting, and other resistive loads.
• Automation Systems: Used in conjunction with PLCs (Programmable Logic Controllers) and other industrial control devices as the final switching element for low-power applications.
