Schneider Electric (Square D) LRD350 Overload Relay 37-50A

The Schneider Electric (Square D) LRD350 Overload Relay is an essential electrical protection system which protects HVAC system motors from both overcurrent and thermal overload situations. The thermal-magnetic relay operates by continuously measuring motor current until it reaches an adjustable threshold between 37-50A for a specific time period which triggers the relay to cut off power supply to protect the motor from damage. The system protects equipment investments by avoiding motor breakdowns and extends the operational time of vital HVAC system components including compressors fans and pumps. The protection system provides operational reliability and increases the durability of connected equipment.
