The TeSys LRD thermal overload relay is a protective device used for 3-phase motors rated at 7.5kW when operating at 400V. It ensures the motor is safeguarded from overheating and potential electrical faults.

Key Features:

• Current Rating: 18A at 690V maximum.
• Thermal Setting Range: Adjustable between 12A to 18A, allowing customization to match motor requirements.
• Tripping Class: Designed with Class 10A tripping, which means it responds quickly to overload conditions.
• Differential Device: Equipped with phase failure and load unbalance detection to detect potential issues in the motor operation.
• Control Elements: The relay has a thermal adjustment dial, a manual-automatic reset selector, a test selector for simulating a tripping event, reset and stop buttons, and a flag indicator.
• Auxiliary Contacts: Provides 2 auxiliary contacts (1 Normally Open and 1 Normally Closed) for fault signalling purposes.
• Transparent Cover: The settings are protected by a transparent cover that can be locked using a seal for security.
• Connection: It connects easily to 3-pole contactors LC1D09-D38 via screw clamp terminals.
• Mounting Options: Can be mounted on a DIN rail or fixed with screws separate from the contactor.
• Terminal Block: A separate terminal block (LAD7B106) can be ordered to facilitate the connection.
• Certified Standards: Meets multiple standards such as IEC, UL, CSA, CCC, EAC, ATEX, and Marine, ensuring its reliability and safety.
• Environmentally Compliant: Green Premium compliant (RoHS/REACH), demonstrating its adherence to eco-friendly standards.
