Standards
IEC 61643-21
Slimline hardware with push-in terminals enables rapid retrofits and reduces wiring errors, accelerating commissioning and lowering field labor costs while maintaining robust overvoltage protection for industrial control panels. This translates to higher equipment availability and predictable maintenance windows in automated facilities. The LED status indicator provides real-time health monitoring and quick fault diagnosis, supporting proactive maintenance programs and minimizing unexpected outages in sensor networks and PLC inputs. Rated current of 145 mA at 110 V data levels ensures the device suppresses transient events on 2-wire signal lines without introducing unnecessary impedance, improving signal integrity and safeguarding data integrity in automation loops. RoHS and REACH declarations, along with a CE DoC, simplify regulatory compliance and sustainability reporting for modern plants. Compatibility with ABB Furse SPD families and IEC 61643-21 standards helps customers standardize protection across machines, drives, and control cabinets while keeping installation straightforward and costs predictable.

FAQs
The device uses push-in terminals for quick wiring into 2-wire signal lines. Ensure the panel is de-energized, insert conductors fully, and verify the LED status indicator after connection. Follow the ABB Slimline installation guide for proper clearances, mounting orientation, and compatible enclosure sizes. This approach minimizes wiring mistakes and speeds up commissioning while maintaining reliable surge protection.
This SPD is designed to meet IEC 61643-21 requirements for low-energy surge protection on signal lines. It carries CE DoC and declarations for RoHS and REACH, ensuring regulatory compliance. Its 110 V operation and 145 mA nominal current are aligned with common industrial signal-supply ranges, enabling straightforward integration into existing IEC 61643-21 protected networks without compromising performance.
Yes. The 2-wire signal-line protection with a 110 V data SPD and 145 mA rating is specifically intended for transient suppression on sensor and PLC input circuits. The push-in terminals simplify installation in signal-carrying paths, and the LED status gives immediate visibility of protection health, helping maintain sensor reliability and data integrity in automation networks.
The device includes Declaration of Conformity for CE, RoHS and REACH declarations, and is aligned with IEC 61643-21 standards. This combination supports regulatory compliance, environmental responsibility, and safe cross-border use in industrial environments. Documentation is available through ABB’s data sheets and supplier declarations to verify conformity.
By protecting critical panels, sensors, and PLC inputs from transient overvoltages, the SPD reduces unplanned downtime and equipment wear, delivering measurable uptime gains. The LED health indicator shortens maintenance cycles, while push-in wiring lowers commissioning time. Overall, plants experience lower maintenance costs, fewer fault-induced outages, and improved system reliability over the asset life.
