SIEMENS 3RT1054-1AP36 power contactor

• Rated Operating Voltage: Suitable for AC 50/60Hz, with an operating voltage range of up to 690V, meeting the application requirements of various industrial voltage environments.​

• Rated Current: The rated thermal current reaches 160A, and the rated operating currents under different working conditions are 110A (AC-1), 85A (AC-3), and 52A (AC-4) respectively, making it adaptable to motors and load devices of different power ratings.​

• Rated Insulation Voltage: Up to 1000V, with excellent insulation performance, effectively ensuring the safe operation of the equipment and preventing electrical accidents.​

• Contact System: Made of silver alloy contact materials, it has excellent electrical conductivity and anti-welding properties, capable of withstanding high current impacts, reducing contact wear, and extending the service life. The contact design, combined with arc extinguishing technology, can quickly extinguish the arc when the circuit is disconnected, reducing the damage of the arc to the contacts and equipment and improving operational safety.​

• Electromagnetic System: The optimized electromagnetic mechanism features low power consumption and high reliability. The suction action is rapid and smooth with low noise, enabling stable operation under frequently operated conditions and ensuring the reliable operation of the contactor.​

• Mechanical and Electrical Life: The mechanical life is as high as 20 million times, and the electrical life under the AC-3 usage category can reach 2 million times, suitable for industrial automation production lines and continuously operating power systems with extremely high requirements for equipment durability.​

• Compatibility with Multiple Accessories: It supports the expansion of various accessories, such as auxiliary contact groups, coil surge suppressors, mechanical interlocking devices, etc. By adding an auxiliary contact group, the number of signal feedback contacts of the contactor can be increased, facilitating the implementation of complex electrical control logic. The coil surge suppressor can effectively reduce the voltage impact generated by the electromagnetic coil at the moment of switching on and off, protecting the coil and related electrical components. The mechanical interlocking device can achieve interlocking control between two contactors to prevent phase-to-phase short circuits.​

• Protection Design: The protection level reaches IP20, preventing solid foreign objects with a diameter greater than 12mm from entering, suitable for most conventional industrial environments. Its housing is made of high-strength flame-retardant materials, with good flame-retardant and impact resistance, ensuring the safety of the equipment under harsh working conditions.​

• It adopts a standard 35mm DIN rail installation method, which is simple and quick, saving installation space. It also supports screw installation, flexibly adapting to different control cabinet layouts.​

• The product complies with international standards such as IEC/EN 60947-4-1 and has passed certifications such as CE and UL, ensuring product quality and safety, and can be safely applied to industrial projects worldwide.​
