Description

Schneider Electric LRD03 TeSys LRD Thermal Overload Relay is a protective device used in electrical systems to prevent motors or other equipment from overheating and potentially causing damage or fire hazards. It works by monitoring the current passing through an engine and tripping if it exceeds a predetermined level for a specified period of time. It is designed to operate in a range of 0.25 to 0.4 amperes (A). This means it's suitable for protecting equipment that operates within this current range.

Class 10A is the tripping time characteristic of the relay. It is a specific tripping class defined by standards. It means the relay will trip within a certain time frame when the current exceeds a certain percentage of its rated current. Class 10A relays typically trip within 10 seconds at 600% of their rated current.

In summary, Schneider Electric LRD03 TeSys LRD Thermal Overload Relay is designed for protecting equipment with a current draw between 0.25A and 0.4A. It is of Class 10A, which implies it will trip within a specific time frame when the current exceeds a certain percentage of its rated current.
