Product Introduction
The GE Multilin MIFIIPI11E00HI00 is an economic, high-reliability digital protection relay engineered for primary circuit protection on distribution networks, as well as backup protection for transformers, generators, and industrial motors.
As part of the streamlined MIF II product family, this unit provides phase and ground time overcurrent (TOC), instantaneous overcurrent (IOC), and thermal image protection. Featuring standard IEC curve capabilities, event recording, and built-in Modbus RTU communication, it offers a precise and scalable solution for modernizing or maintaining critical electrical infrastructure without complex network overhead.

Compliance & Standards Alignment
- Designed and manufactured in accordance with strict international electrical protection standards (IEC, CE conformity).
- Built for high resilience against electromagnetic interference (EMI/RFI) typical of heavy switchgear environments and high-voltage substations.
Technical Note: The part code designation
11indicates 1A phase and ground CT inputs, while theHIsuffix specifies the high-voltage control power range (110–250 VDC / 110–230 VAC). Ensure that your station battery or auxiliary supply voltage aligns strictly with these ratings before powering up the unit.
Storage & Asset Preservation Guidelines
- Store the relay inside its original anti-static ESD package to protect internal microprocessor logic and communication transceivers.
- Keep warehouse storage environments clean, dry, and temperature-controlled with relative humidity kept under 60%.
- Avoid heavy mechanical impacts or dropping the device to prevent cracking the LCD display window or damaging internal terminal assemblies.
Physical Installation Prerequisites
- Ensure that all switchgear control power feeds, main breaker trip circuits, and current transformer (CT) secondary leads are completely de-energized and shorted/isolated (LOTO) prior to physical installation or wiring.
- Secure the relay chassis cleanly into the switchgear panel cutout, ensuring tight gasket compression and a solid low-impedance connection to the rear earth-ground terminal.
- Double-check CT polarity and wiring connections to prevent open-circuit high-voltage hazards on the 1A secondary lines during primary energization.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this GE Multilin relay?
A: Microprocessor-based digital protection relays, switchgear control monitors, and electrical protective devices typically classify under HS code 8536.49 (Relays) or 8538.90. Confirm final parameters with your licensed customs broker.
Q: Can this relay be linked to a plant SCADA or DCS network?
A: Yes. The rear RS485 port supports Modbus RTU communication, which can easily be bridged to an Ethernet backbone using an industrial serial-to-Ethernet gateway (such as a Multilin MultiNet device).
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market conditions, inventory status, and unit condition (New Surplus vs. Refurbished Core); contact our technical sales desk for a formal, time-sensitive quotation.
