The TeSys Deca thermal relays, formerly known as TeSys LRD, are designed to provide reliable overload protection for motors up to 150 A (75 kW / 400 V). Here are their key features:

1. Overload Protection: These thermal relays are specifically engineered to protect motors from overload conditions. They monitor the motor's current and trip the circuit when the current exceeds the preset threshold, preventing damage to the motor from overheating.
2. Coordinated with TeSys Deca Contactors and Circuit-breakers: The thermal relays are coordinated with TeSys Deca contactors and circuit-breakers, ensuring seamless integration and optimal performance within motor control systems. This coordination enhances system reliability and efficiency.
3. Compact Design: TeSys Deca thermal relays offer a flexible and compact design, allowing them to be fitted directly onto TeSys Deca contactors for space-saving installations. Alternatively, they can be installed apart from the contactors using accessories, providing flexibility in system configuration.
4. Wide Motor Range Support: The TeSys Deca thermal relays support a wide range of motors, from 0.06 kW to 75 kW. This versatility makes them suitable for various motor applications across different industries.
5. Reliable Protection: With their robust construction and precise tripping characteristics, TeSys Deca thermal relays provide reliable protection for motors against overload conditions. They help ensure the safe and efficient operation of motor-driven equipment.

Overall, the TeSys Deca thermal relays, formerly named TeSys LRD, offer a flexible and reliable solution for overload protection in motor control applications. With their coordination with TeSys Deca contactors and circuit-breakers, they provide an integrated and efficient system for motor protection.
