ABB 1SAP250100R0001 Shunt Trip Unit (for Low-Voltage Circuit Breakers)

Description

The AX521-based module delivers four AI and four AO channels with options for common signal types (U, I, RTD) and scalable performance across installations. Expect precise signal conditioning, good channel-to-channel isolation, and robust protection against electrical noise typical in industrial environments. The DIN-rail form factor simplifies retrofits and expansions, while the module’s wiring simplicity reduces commissioning time and wiring errors. Compatibility with ABB’s configuration and diagnostic tools enables straightforward commissioning, monitoring, and maintenance, helping operators maintain consistent process accuracy and faster fault resolution. This combination of flexible I/O, reliable isolation, and ecosystem alignment makes the AX521 family a dependable workhorse for mixed-signal control tasks.
