Designed for Reliable Motor Protection:A thermal overload relay specifically used for overload and phase-loss protection of three-phase AC motors, preventing damage due to prolonged overcurrent or phase failure, extending motor service life.
Wide Adjustable Current Range:Adjustable current range: 2.6 – 4.0 A, continuously adjustable via rotary dial, suitable for various small-power motor applications, reducing spare parts inventory.
Perfect Match with SIRIUS Contactors:Mounts directly below SIRIUS 3RT2 contactors (e.g., 3RT2015) to form a compact "contactor + thermal relay" motor starter combination, saving space in control panels.
Three-Phase Bimetal Detection with High Accuracy:Uses three-phase bimetallic elements to accurately simulate motor heating; provides reliable tripping even under phase-loss (single-phasing) conditions.
Clear and Visible Status Indication:Features a mechanical fault flag (red trip indicator) and status window for quick visual identification of tripped conditions.
