INTRODUCTION

The ABB REM615E_1G HBMBCAAJABC1BNN11G is a member of the ABB Relion® 615 protection relay family designed for motor protection, motor control, supervision, and feeder management applications. This intelligent electronic device provides advanced protection functions for medium and low-voltage motors operating in industrial plants, offshore platforms, power stations, and marine vessels.

Modern vessels depend heavily on electric motors for critical operations including seawater cooling pumps, ballast pumps, fuel transfer pumps, hydraulic power units, cargo pumps, compressors, ventilation systems, steering gear auxiliaries, and engine room machinery. A failure in any of these motors can result in operational disruption, increased maintenance costs, and potential safety risks.

The ABB REM615 relay continuously monitors motor operating conditions and provides comprehensive protection against overload, short circuit, earth fault, phase imbalance, stalled rotor conditions, thermal damage, and abnormal operating situations. By detecting faults at an early stage, the relay helps ship operators avoid expensive motor failures and unplanned downtime.

SM MARINE SERVICE™ supplies both New Equipment and Reconditioned Equipment for ABB Relion protection systems including REM615 relays, spare parts, repair services, calibration, testing, and technical support.

KEY FEATURES

Advanced Motor Protection

The REM615 continuously monitors motor operating conditions and protects against overload, overheating, phase failure, phase imbalance, locked rotor conditions, and other damaging situations. This protection significantly extends motor service life and improves operational reliability.

Intelligent Fault Detection

The relay detects electrical faults quickly and accurately. Rapid fault detection minimizes equipment damage and allows corrective action before major failures occur.

Integrated Motor Control

In addition to protection functions, the relay supports motor control operations, enabling start, stop, supervision, and remote control functionality through automation systems.

User-Friendly Human Machine Interface

The front-panel display provides clear status information, fault records, measurements, alarm indications, and configuration access. Engineers can easily diagnose and monitor motor performance directly from the relay.

Communication Capabilities

The relay supports modern communication protocols allowing integration with:

• Power Management Systems (PMS)
• SCADA Systems
• Distributed Control Systems (DCS)
• Marine Automation Systems
• Ship Energy Management Systems

Event Recording and Diagnostics

The relay records fault events, disturbances, alarms, and operational data, providing valuable information for maintenance planning and troubleshooting.
