FIN538S1.055.M is listed in the Power Line Filter Modules range at ChipApex. The manufacturer field lists Enerdoor. Its product description is LINE FILTER 55A CHASSIS MOUNT. Review the specifications below when checking this part for your BOM.
The Enerdoor FIN538S1.055.M is a three-phase (Delta) EMC/EMI line filter module designed for industrial power distribution systems. It features a single-stage filtering architecture with terminal block connections, supporting a rated current of 55 A at 50/60 Hz and operating voltages up to 600 VAC. The unit is engineered to mitigate electromagnetic interference while maintaining compliance with UL508A standards, including specific Short Circuit Current Rating (SCCR) requirements for control panels.
Verify the exact part number suffix against official Enerdoor documentation to confirm voltage and current ratings. Ensure the application environment matches the specified 600V AC limit. Check for physical mounting bracket integrity during inspection, as storage marks or bends may affect installation stability in critical setups.
Select this model when a three-phase Delta configuration is required for 55 A applications. Confirm that the system voltage does not exceed 600 VAC. Verify that the terminal block interface aligns with existing wiring harnesses and busbar specifications within the target control panel design.
This component belongs to the Enerdoor FIN538 series of power line filter modules. The series specializes in high-attenuation EMC solutions for industrial and medical sectors. Enerdoor distinguishes itself by providing filters that meet strict UL508A SCCR standards, addressing common limitations found in generic filter manufacturers regarding short-circuit protection capabilities.
Consult Enerdoor technical data for direct cross-references. Generic substitutes may lack the verified UL508A SCCR rating essential for compliant panel assembly.
