GE Multilin MIVII1000E00HI00 Motor Protection Relay – Smart, dependable protection for low/medium-voltage motors

The GE Multilin MIVII1000E00HI00 is part of the well-known MIV II series used for comprehensive motor protection and control. From my experience, plants often choose this model when they need robust thermal protection, fast trip logic, and straightforward integration into existing RS‑485 networks without a steep learning curve. It typically suits retrofit projects on pumps, fans, conveyors, and compressors where downtime has to be measured in minutes, not days.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week for in-stock; no more than one month at the latest
• Payment: 50% advance payment, full payment for delivery
• Express options: FedEx, UPS, DHL

Key Features

• Comprehensive motor protection – Typically includes thermal overload modeling, short/overcurrent, phase unbalance/negative-sequence, jam/stall, and start supervision to cover most MV/LV induction motor risks.
• CT-based measurement – 3-phase plus ground CT inputs (1 A/5 A nominal), giving accurate fault detection without adding PTs in most applications.
• Programmable I/O – Discrete inputs for status/permits and Form‑C relay outputs for trip/alarms, so you can tailor logic to your MCC or DCS needs.
• Event records and diagnostics – Time-stamped events and trip logs help maintenance teams see what happened and why, which usually shortens restart times.
• Industrial communications – In many cases, RS‑485 (Modbus RTU) is available for fast integration to PLC/SCADA; a local RS‑232 port is often provided for setup.
• Front HMI interface – You might notice that local indication and keypad navigation make commissioning and troubleshooting quicker on the panel door.
• Retrofit-friendly case – Panel/flush mounting, with typical Multilin cutout dimensions, eases replacement of older relays one-for-one.

Technical Specifications

Note: Option code “MIVII1000E00HI00” appears to represent a standard motor protection build without extended option cards; if you require a specific I/O or comms variant, share your exact option breakdown and we’ll verify.

Application Fields

This model is used widely across continuous-process plants where motor uptime is critical:

• Water & wastewater – high-service pumps, blowers, clarifier drives
• Oil & gas – booster pumps, compressors, cooling fans
• Mining & metals – conveyors, crushers, slurry pumps
• Pulp & paper – refiners, vacuum pumps, process fans
• Chemicals – agitators, extruders, chilled-water pumps
• Power & utilities – auxiliary motors and balance-of-plant drives

A maintenance manager told me their team swapped this into a pump MCC and, after mapping a handful of Modbus registers, they had trips and alarms trending in under an hour. That tends to be the norm with MIV II hardware—little drama, quick commissioning.

Advantages & Value

• Reliability in harsh environments – Designed for industrial switchgear/MCC panels, with protective algorithms that remain stable under noise and load swings.
• Compatibility – Common CT ratios (1 A/5 A), Modbus RTU, and typical Multilin cutouts make it a practical drop-in for many retrofits.
• Lifecycle cost savings – Solid protection logic reduces nuisance trips; quicker fault diagnosis means fewer maintenance hours and faster restarts.
• Support and availability – We typically ship in one week if in stock; configuration help and wiring guidance are available on request.

Installation & Maintenance

• Panel/Cabinet – Install in a clean, dry enclosure meeting your site’s MCC/switchgear standard; allow front clearance for HMI access and rear clearance for terminal wiring.
• Wiring – Observe CT polarity and shorting block practices; segregate low-level signal wiring from power conductors; earth the relay per GE guidelines to minimize noise.
• Ventilation – Provide adequate airflow around the relay; avoid hotspots near soft starters or VFDs; keep ambient typically within -20 to +60 °C.
• Commissioning – Verify CT ratios, motor FLA, thermal model settings, and trip/alarm logic before energizing; test digital I/O mapping to the DCS/PLC.
• Routine care – Periodically clean dust from the front panel; review event logs after trips; perform annual functional tests. Firmware updates (where applicable) should be applied during planned outages.

Quality & Certifications

• Conforms to typical GE Multilin protection relay standards, including IEC 60255 categories (protection relays)
• CE and UL/cUL compliance are commonly available on MIV II series; CSA markings are present on many builds
• RoHS status varies by production lot; we can confirm for the specific unit offered
• Manufacturer warranty per GE policy; our commercial warranty coverage is 365 days

Tip: If you’re replacing an existing MIV/MIV II, send a photo of the nameplate and option string. We’ll verify power supply, I/O count, and comms so the replacement lands as a plug‑and‑play match.
