Description

Schneider Electric LRD21 TeSys LRD Thermal Overload Relay is a protective device used in electrical circuits to protect motors and other equipment from overloading. It works by monitoring the current flowing through a circuit, and if it exceeds a certain threshold for a specified amount of time, it trips and opens the circuit, thereby preventing damage to the equipment.

12-18A is the range of currents that this particular thermal overload relay is designed to protect against. It means that it is suitable for circuits where the current can vary between 12 to 18 amperes. Class 10A is the tripping time characteristic of the overload relay. In the context of thermal overload relays, different classes have different trip times for a given level of overcurrent. In this case, Class 10A typically means that the relay will trip in 10 seconds when the current exceeds the specified threshold.
