The TeSys LRD thermal overload relay is engineered to protect 3-phase motors ranging from 1.1 kW to 1.5 kW at 400V. It features a thermal setting range of 2.5–4A and a tripping class of 10A, ensuring reliable motor protection through precise thermal overload detection with added phase failure and load unbalance monitoring.

Key Features:

• Thermal setting range: 2.5–4A with a tripping class of 10A for accurate motor protection.
• Suitable for motors rated 1.1–1.5 kW at 400V.
• Detects phase failure and load unbalance to prevent motor damage.
• Equipped with a thermal adjustment dial, manual/automatic reset selector, test selector for trip simulation, reset and stop buttons, and a flag indicator for easy operation and status monitoring.
• Comes with 2 auxiliary contacts (1NO + 1NC) for fault signaling.
• Settings secured by a transparent cover that can be locked and sealed for tamper protection.
• Screw clamp terminals for direct connection to bottom terminals of 3-pole contactors LC1D09-D38.
• Mounts on DIN rail or via screw fixing, can be installed separately from contactors using optional terminal block LAD7B106.
• Certified to multiple international standards: IEC, UL, CSA, CCC, EAC, ATEX, Marine.
• Green Premium compliant with RoHS and REACH directives for environmental safety.

Benefits:

• Provides precise and reliable thermal overload protection to extend motor life.
• Detects phase loss and load imbalance, preventing costly motor failures.
• User-friendly controls and indicators simplify commissioning, operation, and maintenance.
• Lockable adjustment cover prevents unauthorized setting changes, ensuring system integrity.
• Compatible with conventional contactors and flexible mounting options support diverse installation needs.
• Meets stringent safety, quality, and environmental standards for dependable industrial use.
