Power Line Filter Modules Procurement Notes

Verify the specific part number ESP-03-472-D against official Cosel datasheets to confirm technical parameters. Ensure compatibility with 250VAC/VDC systems and 3A load requirements. Check for required certifications such as cURus or VDE based on regional regulations. Confirm DIN rail mounting constraints and terminal block wiring methods before integration into the design.

Power Line Filter Modules Selection Notes

Select this model for single-phase circuits requiring 3A capacity and 250V ratings. The screwless terminals simplify assembly compared to screw-type alternatives. Verify that the 2.2 nF capacitance meets system leakage current limits. Ensure the operating temperature range of -40°C to 85°C suits the environmental conditions. Consider the single-stage design if higher attenuation is not critical.

Power Line Filter Modules Part Context

This component belongs to the ESP series of power line filters from Cosel USA, Inc. The series offers various current ratings and configurations for EMC/EMI suppression. The ESP-03-472-D specifically denotes the 3A variant with screwless terminals and DIN rail compatibility. It is designed for general-purpose applications where compact size and reliable connection are prioritized.

Power Line Filter Modules Replacement Considerations

The EAP-03-472-D is a similar single-phase filter but uses terminal blocks instead of screwless connections. Verify mechanical fit and termination method differences before substitution. Other ESP variants may offer different current ratings or capacitance values.
