Description
Product Overview
The ABB REC650 1MRK008514-AA is a high-performance motor soft starter designed to control the start, stop, and speed of three-phase induction motors in industrial automation systems. As part of ABB’s PSE (Process Starter Equipment) series, the REC650 combines advanced electronic control with rugged mechanical design to reduce mechanical stress on motors and connected equipment, minimizing wear and tear while optimizing energy consumption. Engineered for applications ranging from pumps and fans to conveyors and compressors, this soft starter is ideal for industries requiring smooth motor acceleration, such as manufacturing, water treatment, and power generation.
The ABB REC650 1MRK008514-AA features a compact footprint and intuitive interface, making it easy to integrate into new or existing motor control centers (MCCs). Its core functions include voltage ramp starting, current limit control, and dynamic braking, all configurable via the built-in LCD display or ABB’s DriveComposer Pro software. By replacing traditional direct-on-line (DOL) starters, the REC650 reduces inrush currents by up to 70%, extending motor and system lifespan while complying with energy efficiency standards like IEC 60947-4-2. Positioned as a reliable and cost-effective solution, the REC650 enhances operational efficiency by enabling precise motor control and proactive maintenance through real-time diagnostic feedback.

REC650 1MRK008514-AA
Main Features and Advantages
Smooth Motor Control and Energy Efficiency: The REC650 offers multiple starting modes to suit different applications. Its voltage ramp mode gradually increases stator voltage, reducing mechanical stress on gears and belts, while the current limit mode restricts inrush current to a preset value, preventing overloads in sensitive systems like water pumps. By optimizing starting parameters, the soft starter can reduce energy consumption by up to 15% in variable-load applications, such as HVAC systems that operate at partial capacity.
Compact Design and Easy Integration: With a width of just 150 mm, the REC650 fits into space-constrained control panels, ideal for retrofitting older systems. The plug-and-play design allows quick installation, while the front-panel LCD (with multi-language support) enables on-the-fly parameter adjustment without additional software. For remote monitoring, optional communication modules (e.g., Profibus DP) enable integration with PLCs or SCADA systems, providing real-time data on motor status, energy usage, and fault history.
Robust Protection and Diagnostics: The REC650 includes comprehensive protection features, such as overload protection (thermal modeling per IEC 60287), phase imbalance detection, and short-circuit withstand capability (up to 50 kA). Built-in diagnostics monitor motor temperature, voltage fluctuations, and contactor wear, triggering alarms or shutdowns to prevent catastrophic failures. The soft starter’s durable thyristor-based design and conformal-coated PCBs ensure reliable operation in harsh environments, including high humidity or dusty industrial sites.

Application Field
The ABB REC650 1MRK008514-AA is widely used in industries where motor starting performance and reliability are critical:
- Water and Wastewater: Controls pumps in water treatment plants, ensuring smooth start-up to avoid water hammer effects in pipelines. For example, in a wastewater treatment facility, the REC650 manages aeration blowers, adjusting speed to match biological process demands and reduce energy costs.
- Manufacturing and Logistics: Powers conveyors, mixers, and packaging machines in food and beverage factories, where frequent start-stop cycles require gentle motor acceleration to prevent product spillage or equipment damage. In a bottling plant, the soft starter ensures consistent movement of glass bottles along conveyors, minimizing breakage.
- HVAC Systems: Optimizes fan and pump motors in commercial buildings, enabling variable speed control to match heating or cooling demands. The REC650’s dynamic braking feature quickly stops pumps during system shutdowns, reducing mechanical stress on valves and pipes.
- Power Generation: Used in auxiliary systems like coal feeders or cooling fans in thermal power plants, where reliable motor control is essential for uninterrupted operation. The soft starter’s ability to handle voltage sags ensures stable performance during grid fluctuations.

Installation and Maintenance
Pre-installation preparation: Mount the REC650 on a DIN rail or panel, ensuring adequate spacing for heat dissipation (minimum 50 mm between units). Connect motor and power cables using stranded copper wires (max. 35 mm²), tightening terminals to the specified torque (8–12 N·m). Configure starting parameters (e.g., ramp time, current limit) via the LCD or DriveComposer Pro, matching the motor’s full-load current (FLC) and application requirements. For safety, ensure the enclosure provides IP20 or higher protection against accidental contact.
Maintenance recommendations: Regularly inspect the soft starter’s terminals for loose connections or signs of overheating, especially in high-vibration environments like manufacturing floors. Clean dust from the heatsink fins every six months using compressed air to maintain optimal thermal performance. Monitor diagnostic data (e.g., thyristor conduction cycles, fault logs) to predict component wear and schedule preventive maintenance. Replace the internal battery (for real-time clock) every 5 years and update firmware annually to access new features or compatibility updates.
