ABB PSR9-600-11 Programmable Protection Relay

ABB PSR9-600-11 is a compact open softstarter in ABB’s PSR family, designed to limit inrush current and provide controlled acceleration for three-phase induction motors without the need for fieldbus communication. It is rated for a maximum main voltage of 600 V and a rated current of 9 A (Ie), and it accepts line voltages from 208 to 600 VAC while using a 24 V AC/DC control supply. The device carries ABB order code 1SFA896105R1100, and ABB’s e-catalog lists it for open softstarter applications. The PSR9-600-11 is intended for panel installations and can be paired with ABB manual motor starters (MMS), with mechanical coupling kits available to support the integration. As with other PSR softstarters, it does not include built-in motor overload protection; an external overload device sized to the motor FLC and appropriate short-circuit protection upstream are required. Common applications include light- to medium-duty starts for fans, pumps, and conveyors in commercial or industrial panels where a compact, non-networked softstart is sufficient.
