The SIEMENS 6EP1961-2BA21 is a SITOP PSE200U selectivity module designed to manage and protect multiple 24 V DC power channels in industrial systems. It accepts a 24 V DC/40 A input and distributes power to four individually protected 24 V DC outputs rated at 10 A each, with adjustable trip thresholds from 3 to 10 A for tailored overload protection. Ideal for machines and control cabinets that require selective shutdowns, it simplifies fault isolation and includes a common signaling contact to report channel status for streamlined monitoring and maintenance.
