3RB2056-1FW2 Siemens Relay New Original Plc Programming Controller module

2. Key Selling Points

1. Compact Thermal Overload Relay: Part of the Siemens SIRIUS 3RB2 series, with a space-saving design that directly mounts to SIRIUS contactors (e.g., 3RT2), ideal for motor control applications where panel space is limited.
2. Wide Adjustable Current Range: Adjustable current setting from 10 A to 16 A, suitable for protecting medium-power three-phase AC motors and accommodating various load requirements, reducing spare part inventory.
3. Precise Motor Protection: Provides reliable thermal overload protection and phase-loss (single-phasing) protection, effectively preventing motor damage caused by overloads, stalling, or missing phases, thereby extending motor service life.
4. Mechanical Interlock Design: Enables mechanical interlocking when combined with contactors, ensuring a secure and stable connection between the relay and contactor, preventing loosening and poor contact.
5. Clear Status Indication: Features a visible trip indicator (typically red), allowing quick identification of motor fault conditions and reducing troubleshooting and maintenance time.
