System Compatibility
The GE UR8LV is compatible with the following UR Series relay models when installed in the correct module slot:
- GE C30 / C60 / C70 – Universal Controller & Bay Controller
- GE D30 / D60 – Distribution Protection
- GE F35 / F60 – Feeder Protection
- GE L30 / L60 / L90 – Line Protection
- GE M60 – Motor Protection
- GE N60 – Network Stability
- GE T35 / T60 – Transformer Protection
Always confirm slot designation (e.g., Slot H, Slot J) in your relay order code before ordering.
Selection Guide
- Relay Model: Confirm your UR relay model (e.g., C60, T60) and its order code.
- Slot Position: Identify the target slot (e.g., Slot H = CT/VT input). The digit in UR8LV denotes the slot designation.
- Input Type: Verify CT and VT input ratings match your transformer secondary outputs (e.g., 1A/5A CT, 100V/120V VT).
- Channel Count: Confirm the number of CT and VT channels required for your protection scheme.
- Firmware Version: Check GE EnerVista compatibility matrix for your relay firmware version.

Replacement & Compatibility FAQ
Q: Can I use a UR8IV instead of a UR8LV?
A: Possibly, but the two modules differ in input channel configuration. Verify your relay order code and consult GE documentation or contact Konmask before substituting.
Q: Is the UR8LV compatible with all UR Series relays?
A: The UR8LV is designed for UR platform relays, but slot compatibility depends on your specific relay model and order code. Always verify the slot designation.
Q: Do you supply new or refurbished modules?
A: Konmask supplies new OEM modules as standard. Tested surplus units may be available upon request.
Q: What is the lead time for the GE UR8LV?
A: Standard lead time is 3-10 business days for in-stock units. For out-of-stock items, lead time is quoted individually.
Q: Can Konmask provide a certificate of conformance?
A: Yes. Certificates of conformance and test reports are available upon request for all orders.
