Description
Product Introduction
Undervoltage, overvoltage or frequency excursions can trip critical loads or damage equipment if not cleared quickly. The GE MIVII3000E00HI00 is the MIV II 3000 digital voltage and frequency protection relay from the Multilin M II family. It combines four independent phase under/overvoltage elements, two ground overvoltage elements, voltage unbalance detection and two frequency elements in a single drawout case.
Designed for motors, generators, automatic transfer schemes, lines and busbars at any voltage level, the relay offers configurable logic, dual settings groups, front RS232 and rear RS485 Modbus RTU communication, and field-upgradable flash memory. The HI power-supply option accepts 110–250 VDC or 110–230 VAC. Listed price is reference only—request a quote for current market conditions.
Installation & Configuration Guide
Phase 1 — Pre-Installation (est. 10–15 min)
De-energize the panel and follow lock-out/tag-out. Tools: insulated screwdriver, multimeter, laptop with EnerVista or equivalent software, ESD protection. Record existing settings, CT/VT ratios and wiring. Photograph the rear terminal blocks, drawout mechanism and front-panel LEDs.
Phase 2 — Removal (est. 5–10 min)
Open the drawout handle, disconnect the rear terminal blocks or plug-in connectors, and withdraw the relay. Cap open CT/VT circuits if required and inspect the chassis for contamination or bent pins.
Phase 3 — Installation (est. 10 min)
Confirm the part number is MIVII3000E00HI00 and the HI power-supply range matches the available auxiliary voltage. Insert the relay into the drawout case, reconnect all terminals exactly as photographed, and lock the drawout mechanism.
Phase 4 — Power-On & Testing (est. 15–25 min)
Apply auxiliary power. Verify status LEDs and communication. Download or verify settings via the front RS232 or rear RS485 port. Inject secondary voltages and frequencies to confirm pickup, timing and trip outputs. Check both settings groups if used. Run stable and log the change.
Troubleshooting quick-reference:
- No power → confirm HI supply voltage range and polarity
- Communication fails → check baud rate, Modbus address and cabling
- Incorrect trip → verify VT connections, voltage range setting and logic
FAQ
Can I just drop this in and go?
Only if the wiring, VT ratios and settings match the original relay. Otherwise download the configuration file and re-validate protection elements. Most swaps finish in under an hour when photos and the settings file are available.
What protection functions does the MIVII3000E00HI00 include?
Four phase under/overvoltage elements, two ground overvoltage elements, negative-sequence voltage unbalance, and two under/overfrequency elements.
Is the HI power-supply option universal?
The HI version accepts 110–250 VDC or 110–230 VAC. Confirm the available auxiliary voltage before ordering; a LO version (24–48 VDC) exists for lower-voltage supplies.
