Suitable for
Industrial motor control circuits
HVAC systems and ventilation equipment
Conveyor belt motor protection
Pump and compressor control panels
When it may not be suitable
This relay is not intended for use in circuits exceeding its specified current range of 0.4 to 0.63A. It is also not suitable for applications requiring electronic overload protection or advanced communication features, as this is a traditional thermal-mechanical device.
Key specifications
Adjustable current range: 0.4 to 0.63A
Coil voltage rating: 690V
Weight: 124g
Colour: Multicolour
How to use
The LRD04 relay is designed for direct mounting onto compatible contactors. Installation involves connecting the power leads to the input and output terminals according to the wiring diagram provided with your contactor. Once installed, the current setting dial on the front of the unit should be adjusted to the nominal current rating of the motor being protected. Periodic testing of the trip mechanism is recommended to ensure the device remains functional.
What to consider before purchase
Verify that the motor nominal current falls within the 0.4-0.63A range
Ensure compatibility with your existing contactor model
Check that the system voltage does not exceed the 690V rating
Usage recommendations
Always ensure that the power supply is disconnected before installing or adjusting the relay. Regularly inspect the terminals for tightness to prevent overheating and ensure reliable electrical contact.
