Power Line Filter Modules Procurement Notes

Verify the specific datasheet version to confirm exact leakage current limits under varying temperature conditions. Ensure the installation environment meets the required clearance and creepage distances defined by the UL and CSA certifications. Confirm that the screwless terminal torque specifications are strictly followed during assembly to maintain electrical integrity and safety compliance.

Power Line Filter Modules Selection Notes

Select this model when DIN rail mounting is required for space-constrained enclosures. The 3 A rating suits low-power electronic loads. Verify compatibility with the system's voltage profile (250 VAC/VDC). Consider the screwless termination method if rapid assembly or vibration resistance is prioritized over traditional screw terminals. Check physical dimensions against available DIN rail space.

Power Line Filter Modules Part Context

This component belongs to the ESM series of single-phase power line filters from Cosel. The series offers various current ratings and mounting options. The ESM-03-221-D specifically targets applications requiring compact DIN rail integration with moderate current handling capabilities. It serves as an interface between the power source and sensitive electronic loads to mitigate conducted emissions.

Power Line Filter Modules Replacement Considerations

Direct substitutes include the ESP-03-221-D, which shares similar electrical characteristics but may differ in terminal type or packaging. Cross-reference mechanical dimensions and pinout configurations before substitution. Verify that any alternative part maintains the same certification approvals for the target application region.
