ABB REM615 HCMJAEADABC2BNN11E – Motor Protection & Control IED for Demanding MV/LV Motor Feeders

The ABB REM615 (order code: HCMJAEADABC2BNN11E) is a compact motor protection and control relay from the Relion 615 series. It’s built for fixed-speed motors that need dependable protection against thermal overload, short-circuit, stall/locked-rotor, unbalance, negative-sequence and earth faults—while giving operators clear diagnostics and fast trip logic. From my experience, REM615 fits really well in pump, fan, conveyor and compressor applications, especially where IEC 61850 and modern SCADA connectivity are part of the spec.

Key Features

• Comprehensive motor protection – Overcurrent, thermal overload, start-up/stall supervision, unbalance/negative sequence, earth-fault; designed for medium and low-voltage motors.
• High-fidelity measurements – 3-phase CT inputs plus residual; supports 1 A or 5 A, enabling accurate protection setting and trending.
• Communication-ready – IEC 61850 with GOOSE for fast peer-to-peer trips; Modbus TCP, and in many cases optional legacy protocols for mixed fleets.
• Event and disturbance records – Time-stamped events, fault records and disturbance waveforms help maintenance teams find root causes quickly.
• Intuitive HMI – Front panel with LCD, programmable LEDs and clear text; operators typically get alarm context without opening engineering tools.
• Built for harsh environments – Wide operating temperature and robust EMC immunity; it seems to handle industrial noise better than many general-purpose relays.
• Engineering efficiency – Parameterization via PCM600; templates make repeat projects faster and reduce setting errors.
• Flexible I/O – Binary inputs/outputs sized for common motor feeder schemes; logic is simple to tailor for interlocks and permissives.

Application Fields

REM615 is typically used on:

• MV/LV motor feeders in switchgear (fixed-speed drives)
• Pumps, blowers, fans and compressors in water/wastewater and HVAC
• Conveyors, crushers and mills in mining, metals and cement
• Refining and chemical plants with IEC 61850-based SCADA
• Balance-of-plant motors in power generation and renewables (BOP)

One thing I appreciate is how it handles nuisance trips: the start-up and stall logic is forgiving enough for heavy-duty starts, while still reacting fast to genuine faults.

Advantages & Value for Procurement

• Reliability – Type-tested to IEC 60255 with strong EMC immunity; in most cases, it reduces unplanned downtime compared with generic relays.
• Interoperability – Native IEC 61850 makes integration with modern substations straightforward; Modbus helps with legacy PLCs.
• Lifecycle cost – Reusable setting templates, clear HMI, and built-in recording cut commissioning and troubleshooting hours.
• Availability – Widely used platform with consistent spare part support and long-term firmware maintenance.
• Scalability – I/O and comms options suit everything from simple DOL starters to more complex interlocked schemes.

Installation & Maintenance Tips

• Panel/cabinet – Mount in a clean, ventilated switchgear compartment; allow front access for wiring and HMI. Maintain the panel cut‑out around 170 × 170 mm.
• Wiring – Use shielded twisted pairs for binary/comm signals; route CT/VT leads separately from power cables. Verify CT polarity before first energization.
• Grounding – Bond the relay case and communication screen at a single point to avoid ground loops, especially in high-EMI zones.
• Settings & testing – Commission with PCM600; run primary injection for protection pickup checks. Save a baseline settings file for future reference.
• Firmware – Check periodically for ABB firmware updates; apply during planned outages to keep cybersecurity and protocol stacks current.
• Routine care – Inspect terminals for tightness, clean the front HMI and ventilation paths, review event logs after abnormal starts.
• Safety – Isolate CT circuits correctly (shorting links) before removing connections; use a test switch for safe secondary injection.

Supporting Components (Recommended)

• ABB RTXP 24 Test Switch – Streamlines secondary injection and functional checks; reduces risk when isolating trip circuits during maintenance.
• Industrial Ethernet Switch (IEC 61850‑3 rated) – For substation‑grade networking and GOOSE messaging; typically used for PRP/HSR or ring architectures.
• 1 A / 5 A Class PS CTs (motor feeders) – Correct CT class improves stability on inrush and reliable fault capture.

A maintenance supervisor from a mining site told us the move to REM615 cut troubleshooting time by half because fault records were clear and the logic was easy to visualize in PCM600. That matches what we’ve seen on commissioning jobs too.
