Description

Schneider Electric LRD350 TeSys LRD Thermal Overload Relay is a protective device used in electrical circuits to protect motors and other equipment from damage due to overloading. 37-50A is the current range for which the thermal overload relay is designed to operate. It means the relay is intended for use in circuits where the current is expected to be between 37 and 50 amperes. This is the range at which the relay will start to actuate.

Class 10A is the tripping time characteristic of the thermal overload relay. Class 10A typically means that the relay will trip within 10 seconds when the current exceeds the specified threshold.

So, Schneider Electric LRD350 TeSys LRD Thermal Overload Relays is designed to protect electrical circuits with a current range of 37 to 50 amperes, and it will trip within 10 seconds if the current exceeds its threshold.

Features
