Description

Schneider Electric LRD3363 TeSys LRD Thermal Overload Relay is a protective device used in electrical circuits to protect motors from overloading. 63-80A is the current rating of the relay. It means that the thermal overload relay is designed to handle motors with a current draw between 63 and 80 amperes. This is the range of current that the relay is calibrated to monitor and protect against overloading.

Class 10A is the tripping class of the thermal overload relay. The tripping class determines the time it takes for the relay to trip (i.e., disconnect the motor) under overload conditions. Class 10A means that the relay will trip within 10 seconds when the current exceeds the specified limit.

In practical terms, Schneider Electric LRD3363 TeSys LRD Thermal Overload Relay is suitable for protecting motors that draw between 63 and 80 amperes of current. If the current exceeds this range, the relay will trip within 10 seconds to prevent damage to the motor due to overloading.
