Description
Schneider Electric LRD07 TeSys LRD Thermal Overload Relay is a protective device used in electrical systems to prevent motors from drawing excessive current and overheating. 1.6-2.5A is the current setting of the thermal overload relay. It means that the relay is designed to protect a motor that draws between 1.6 and 2.5 amperes of current.
If the current exceeds this range for an extended period, the relay will trip and disconnect the motor from the power supply. Class 10A is the tripping class of the thermal overload relay. The tripping class defines the response time of the relay under different overload conditions. Class 10A means that the relay will trip in approximately 10 seconds when subjected to an overload condition that is 7 to 10 times the full load current.
Overall, Schneider Electric LRD07 TeSys LRD Thermal Overload Relays are suitable for protecting a motor that has a rated current between 1.6A and 2.5A, and it will respond relatively quickly (within 10 seconds) to severe overloads.
