ОПИСАНИЕ ПРОДУКТА
SCHNEIDER ELECTRIC LRD3322 - Thermal Overload Relay
The SCHNEIDER ELECTRIC LRD3322 is a TeSys LRD series bimetallic thermal overload relay engineered for the protection of three-phase AC motors against overloads, phase failure, and prolonged starting conditions. It integrates directly with TeSys D contactors, providing a compact and robust motor control solution. This device is critical for maintaining operational integrity in industrial applications such as pumping systems, ventilation, and material handling.
