Description

Schneider Electric LRD12 TeSys LRD Thermal Overload Relay is a protective device used in electrical systems to prevent motors from overheating and potentially causing damage or creating a safety hazard. 5.5-8A is the current setting of the thermal overload relay. It implies that the relay is designed to protect a motor with a current draw between 5.5 amperes and 8 amperes. If the current exceeds this range, the relay will trip and disconnect the motor from the power source.

Class 10A is a standard classification system used for thermal overload relays. It indicates the trip time of the relay under a specific overload condition. In this case, Class 10A means that the relay will trip within 10 seconds when the motor current reaches approximately six times the specified current rating (between 33A and 48A in this case, as calculated from the 5.5-8A range).
