FN3258H-30-33

Overview

The Schaffner FN3258H-30-33 is a three-phase EMC/RFI line filter designed for delta configurations. It supports a rated current of 30 A and a maximum voltage of 520 VAC at 60 Hz. The unit utilizes terminal block connections for both input and output terminals. Physical dimensions are characterized by a chassis mount style, with specific measurements including a height of 85 mm, depth of 50 mm, and length of 270 mm. The device operates within a temperature range of -25°C to +100°C.

Feature Summary

• Ultra-compact design optimized for space-constrained motor drive applications
• Terminal block interface for secure electrical connections
• Chassis mounting capability for stable installation

Applications

• Motor drive systems
• Industrial power conditioning
• EMC suppression in delta networks

Procurement Notes

Verify the specific suffix 'H' indicates the delta configuration variant distinct from standard models. Confirm terminal block compatibility with existing wiring harnesses. Ensure the 520 VAC rating aligns with the target system voltage. Validate that the 30 A continuous current capacity meets the load requirements without derating issues under high ambient temperatures.

Selection Notes

Select this model when a delta-connected three-phase filter is required for motor drives. The ultra-compact form factor distinguishes it from larger industrial filters. Ensure the application environment stays within the specified -25°C to +100°C operating range. Verify that the terminal block termination method suits the available connection infrastructure compared to screw or cable lug options.

Part Context

This component belongs to the FN3258 series of ultra-compact EMC filters manufactured by Schaffner. The series is engineered for high-density installations where space is limited. The 'H' designation typically denotes specific internal topology or connection variations within the product family, differentiating it from standard FN3258 variants.

Replacement Considerations

FN3258-30-33 is a related model but may differ in voltage rating (480 VAC vs 520 VAC) and phase configuration. Verify if the standard version supports the required delta network operation before substitution.
