Siemens 3RB2056-1FC2

Reliable Motor Protection with Siemens 3RB2056-1FC2

The Siemens 3RB2056-1FC2 is an advanced electronic overload relay designed to deliver superior protection for motors within the current range of 50 to 200 amps. Engineered with precision for demanding industrial environments, this overload relay belongs to Siemens’ renowned SIRIUS series and is classified as a Size S6 device. It plays a critical role in safeguarding motors from the damaging effects of overloads, phase failure, and prolonged overcurrent conditions. Whether integrated into a motor starter assembly or used in a stand-alone configuration, the 3RB2056-1FC2 ensures extended equipment life and reduced downtime, making it a reliable choice for motor protection in any industrial application.

Versatile Mounting Options and Integration

The 3RB2056-1FC2 is designed for flexible installation, accommodating contactor mounting, and independent stand-alone setups. This versatility allows engineers and system integrators to customize motor protection systems according to specific spatial and operational constraints. Its main circuit has a robust busbar connection, ensuring secure, high-conductivity electrical links for high-current applications. For the auxiliary circuit, screw terminals are provided, allowing for fast and secure wiring. This design approach supports straightforward installation and future system maintenance, reducing complexity and enhancing operational efficiency.

Precision Class 10E Tripping for Accurate Motor Response

One of the standout features of the Siemens 3RB2056-1FC2 is its Class 10E tripping characteristic. This tripping class ensures that the overload relay reacts with the ideal time delay for standard motor applications, providing prompt protection while avoiding unnecessary interruptions. The Class 10E profile is particularly effective for general-purpose motors, balancing response speed and durability under varying load conditions. This ensures that motors are protected from heat build-up due to overloads without prematurely tripping in the face of momentary current spikes.

Manual and Automatic Reset Capability

To further enhance usability, the 3RB2056-1FC2 features both manual and automatic reset options. This functionality allows users to tailor reset behavior based on the application’s requirements and safety protocols. Manual reset is particularly beneficial during maintenance or troubleshooting, ensuring operators fully control the system reactivation. On the other hand, automatic reset is ideal for processes requiring minimal downtime and automatic recovery after non-critical overload events.

Support and Reliability from MRO Electric

Purchasing the Siemens 3RB2056-1FC2 from MRO Electric and Supply means customers receive a high-quality motor protection device and the added benefit of a 2-year warranty and free shipping. MRO’s commitment to quality and customer service ensures peace of mind, making this overload relay a wise investment for any automation or motor control system.
