Description
The Schneider Electric (Square D) LR9D32 Overload Relay protects HVAC equipment motors through its adjustable current range between 6.4-32A. The system tracks motor current consumption persistently until the measured value surpasses a predetermined threshold for an established time which activates the relay to cut off power and protect the motor from damage. The overload relay operates as a standard protection part which safeguards motor components in HVAC applications such as air conditioners and heat pumps and ventilation systems. The use of overloads contributes to two main advantages, they protect equipment from motor failure expenses and system downtime while extending their reliability period and operational durability.
