Frequently Asked Questions - LR65 SCHNEIDER
How do I install the LR65 motor protection circuit breaker?
Mount the device on a standard 35mm DIN rail. Ensure the rail is grounded. Connect the power supply to the main terminals (L1, L2, L3) and the motor to the outgoing terminals (T1, T2, T3). Tighten screws to the recommended torque.
What is the rated current range of the LR65?
The LR65 has an adjustable current rating from 0.1 A to 0.4 A. Use the dial on the front to set the desired value.
Can the LR65 be used for single-phase motors?
Yes, you can use it for single-phase motors by connecting only one phase (L1) and the neutral. Note that phase failure protection will be disabled.
How do I reset the LR65 after a trip?
After the fault is cleared, press the blue reset button on the front of the device. For automatic reset, set the mode selector to 'AUTO'.
What does the LED indicator mean?
A steady green LED indicates normal operation. A red flashing LED means the device has tripped. No light indicates no power supply.
What is the maximum wire size for connection?
The terminals accept wires up to 4 mm² (AWG 12). Use crimp ferrules for stranded wires.
How often should I test the LR65?
Test the trip mechanism at least once a year. Press the test button (marked 'T') to simulate overload. The device should trip immediately.
Is the LR65 suitable for harsh environments?
The device has IP20 protection, so it is not dust- or water-tight. Use it inside a control panel with appropriate sealing.
Can I add remote monitoring to the LR65?
Yes, you can mount an auxiliary contact (e.g., GVAE11) to the side of the device for remote status indication.
What does the 'phase failure' protection do?
If one of the three phases is lost, the LR65 will trip after a short delay, preventing motor damage due to single-phasing.
