3-134-822

Overview

The Schurter 3-134-822 is a single-phase AC power line filter from the FMAB NEO series, designed for Class II protection. It features a DIN rail mounting style with quick connect terminals. The component is rated for 250 VAC and operates at 60 Hz. Official documentation indicates current ratings of either 3 A or 4 A depending on the specific datasheet version referenced. It utilizes a single-stage filtering configuration to attenuate electromagnetic interference in AC power circuits.

Feature Summary

• Single-stage EMI/EMC noise attenuation for AC power lines
• DIN rail mounting for standardized panel integration
• Quick connect terminal interface for simplified wiring
• Class II insulation protection rating

Applications

• Healthcare equipment requiring reliable noise attenuation
• Medical devices demanding high-performance filtration
• Industrial control systems utilizing DIN rail enclosures

Procurement Notes

Verify the exact current rating (3 A vs 4 A) against the manufacturer's latest datasheet, as sources vary. Confirm compliance certifications such as CSA, ENEC, UR, and IEC standards required for your specific regional deployment. Ensure the quick connect terminal type matches your existing harness specifications before procurement.

Selection Notes

Select this model when DIN rail mounting is preferred over panel mount configurations. It is suitable for applications requiring Class II isolation and single-phase filtering. Compare the 3 A and 4 A variants based on the maximum load current of the protected circuit. Ensure the operating frequency aligns with the 60 Hz specification provided in the technical data.

Part Context

This component belongs to the Schurter FMAB NEO series, which focuses on compact power line filters. The series is engineered for medical and industrial sectors where space efficiency and robust noise suppression are critical. It complements other Schurter power entry modules by providing dedicated filtering capabilities within standard enclosure formats.

Replacement Considerations

The 3-134-823 is a documented variant within the same FMAB NEO series. Verify if the 4 A rating of the 823 is compatible with your circuit requirements compared to the 3 A rating found in some 822 datasheets. Both share similar mounting and terminal characteristics.
