Siemens 3RT2016-1JB42 SIRIUS Power Contactor 9A, 4kW, 24V DC, 3-Pole, Size S00 Original Brand New

Overview: Siemens 3RT2016-1JB42 SIRIUS 3RT2 DC Contactor

The Siemens 3RT2016-1JB42 is a compact, high-performance power contactor from the trusted SIRIUS 3RT2 series, designed for switching motors and general resistive loads. This model is specifically engineered for modern industrial control applications, making it ideal for direct use with PLC outputs due to its low power 24V DC coil and integrated suppressor diode. Its robust design in the compact S00 frame size ensures reliable operation in diverse industrial environments.

Benefit

• Low power consumption, minimal residual current, and protection against switching surges (noise reduction) for direct, safe control by sensitive PLC outputs.
• Saves valuable space within control cabinets, optimizing panel design and density. Mechanical service life of up to 30 million operating cycles typical, ensuring long-term reliability and reduced maintenance.
• Provides secure and reliable wiring connections for main and auxiliary circuits.
• Part of the globally recognized Siemens SIRIUS modular system, guaranteeing tested quality, high shock resistance, and worldwide applicability (e.g., up to 690 V operating voltage, -25 to +60 °C operating temp).
• A focused, efficient solution ideal for dedicated coupling tasks where no additional auxiliary contacts are required, reducing complexity.

Function & Application

The 3RT2016-1JB42 functions as a robust electromagnetic switch, primarily used for remotely making and breaking electrical circuits under normal load conditions.

• Motor Switching: Ideal for starting and controlling 3-phase AC motors up to 4 kW (at 400V).
• Load Switching: Suitable for general-purpose switching of resistive loads (e.g., heating elements, lighting).
• Coupling Function: Perfect as a coupling contactor for connecting low-power logic signals (like 24V DC PLC outputs) to higher power load circuits.
