The Schneider Electric LRD21 Overload Relay LC1 D18 D32 12-18/10 is a versatile and reliable electrical protection device designed for commercial and industrial applications. This overload relay is part of Schneider Electric's LRD series, which is known for its high performance and robustness.
The LRD21 is a Type B overload relay, which means it provides both overcurrent and short-circuit protection. It is rated for a current range of 12 to 18 amperes, making it suitable for a wide range of electrical loads. The relay has a trip class 10, which means it trips at 10 times the rated current, providing excellent protection against overloads.
The LRD21 comes with three separate trip coils (D18, D24, and D32), allowing for flexible application. The D18 and D24 coils have a trip current of 18 and 24 amperes, respectively, while the D32 coil has a trip current of 32 amperes. This feature allows for the selection of the appropriate coil based on the specific application requirements.
The relay is housed in a robust LC1 enclosure, which is suitable for mounting in panelboards and switchboards. The enclosure is designed to withstand harsh environmental conditions, including high temperatures and humidity. The LRD21 also features a self-resetting mechanism, which allows the relay to reset automatically after a trip, thereby reducing downtime and maintenance costs.
In summary, the Schneider Electric LRD21 Overload Relay LC1 D18 D32 12-18/10 is a high-performance and reliable electrical protection device that provides overcurrent and short-circuit protection. Its versatile tripping characteristics and robust enclosure make it an ideal choice for commercial and industrial applications.
