Power Line Filter Modules Procurement Notes

Verify the specific ordering suffix to ensure correct terminal type and certification requirements. Confirm that the 3 A current rating and 250 V voltage specifications align with the target circuit design. Check for RoHS compliance status in the latest manufacturer documentation before finalizing procurement orders.

Power Line Filter Modules Selection Notes

Select this model when DIN rail mounting is required for single-phase applications. Ensure the 3 A current capacity meets the load requirements. Consider the low leakage current characteristic if connected to equipment with strict safety isolation limits. Verify compatibility with existing terminal block infrastructure.

Power Line Filter Modules Part Context

This component belongs to the ESP series of power line filters from Cosel. The series focuses on providing effective noise suppression for single-phase AC and DC circuits. The ESP models are characterized by their compact form factor and standardized mounting options, facilitating easy integration into various industrial enclosures.

Power Line Filter Modules Replacement Considerations

Direct substitutes include the ESP-03-471 (non-D variant) if screw terminals are acceptable instead of screwless blocks. Other ESP series variants may serve as alternatives if current ratings differ. Always verify pinout and mounting dimensions before substitution.
