3-137-026

Overview

The SCHURTER 3-137-026 is a single-phase EMC/EMI power line filter module from the FMAB NEO series. It features a PE choke and supports a rated current of 20 A at 250 VAC (50–60 Hz). The unit utilizes quick-connect terminals for circuit integration. Designed for industrial applications, it provides electromagnetic interference suppression within a compact form factor suitable for panel mounting or internal equipment installation.

Feature Summary

• Single-stage EMI/EMC filtering with integrated PE choke
• Quick-connect terminal interface for rapid assembly
• Compact modular design for space-constrained enclosures

Applications

• Industrial control panels requiring noise suppression
• Medical equipment power input stages
• Automotive testing and diagnostic systems

Procurement Notes

Verify the specific datasheet revision to confirm terminal orientation and mounting hole dimensions. Ensure the operating environment temperature remains within the component's specified range. Confirm that the 20A rating aligns with the downstream circuit protection requirements. Check for any regional certification updates such as UL or CE before final procurement approval.

Selection Notes

Select this model when a single-phase solution with integrated common-mode choking is required. The quick-connect style suits automated assembly lines. Compare against the broader FMAB NEO series if higher current ratings or different voltage classes are needed. Verify compatibility with existing PCB or wire harness layouts due to the specific terminal type.

Part Context

This component belongs to Schurter’s FMAB NEO series of power line filters. The series focuses on providing effective EMI suppression in a small footprint. The 3-137-026 variant specifically addresses 20A applications. It complements other Schurter components like fuse holders and switches in complete power management assemblies.

Replacement Considerations

Consult official Schurter substitution guides for direct equivalents. Verify that alternative models maintain the same 20A rating and 250VAC specification. Ensure physical dimensions and terminal types match the existing board layout to avoid redesign.
