Substitute Part Grouping Explanation

The FN3258-30-47 can be substituted with the FN3258-30-33 based on the following critical parameters that remain constant across both parts:

• Filter Type: Three Phase (Delta)
• Configuration: Single Stage
• Current Rating: 30 A
• Voltage Rating - Phase to Ground/Neutral: 277 V
• Voltage Rating - Phase to Phase: 480 V
• Frequency - Operating: DC ~ 60Hz
• Mounting Type: Chassis Mount
• Termination Style: Terminal Block
• Operating Temperature Range: -25°C ~ 100°C
• Approval Agencies: CSA, ENEC, UR
• Series: FN 3258

The primary distinction between these parts is product status and packaging format. The FN3258-30-33 is an active product with tray packaging, whereas the FN3258-30-47 is obsolete with different packaging specifications.
