The Siemens SIRIUS 3RT1975-5AD31 is an essential accessory designed to expand the control capabilities of the SIRIUS series 3RT107 and 3RT147 power contactors. This robust changeover operating mechanism provides the necessary coil power for reliable switching and control in demanding industrial applications. Engineered for maximum flexibility, it operates on a wide control voltage range of 42 V to 48 V, accommodating both AC (50...60 Hz) and DC power sources. The design includes both Standard and Economy circuit functionality, allowing for reduced holding power consumption once the contactor is closed, saving energy and minimizing heat generation. Connection is made simple and secure via screw terminals.
Contactor Control: Supplies the electrical power required to actuate the main contacts within compatible 3RT107 and 3RT147 contactors.
Changeover Operation: Enables the contactor's switching function to change the state of the power circuit.
Dual-Voltage/Current Compatibility: Seamlessly functions with either AC (50 Hz or 60 Hz) or DC power at 42-48V, simplifying inventory and application planning.
Energy Efficiency: The integrated economy circuit significantly reduces the coil's power consumption after the initial pull-in, enhancing efficiency and component longevity.
Versatile Power Application: The wide 42-48V AC/DC operating range makes it suitable for diverse global electrical standards and control architectures.
Cost and Energy Savings: The economy circuit feature minimizes continuous power draw and heat, reducing operating costs and extending the lifespan of the equipment.
Robust and Reliable: Built to the high standards of the Siemens SIRIUS family, ensuring long-term reliability in harsh industrial environments.
Easy Integration: Designed specifically for 3RT107 and 3RT147 contactors, guaranteeing a perfect fit and straightforward installation via established screw terminals.
Optimized Inventory: One operating mechanism covers both AC and DC needs, simplifying procurement and spare parts management.
