Equivalent & Substitute Parts for 2564000 Fuse Block

Part Overview

The 2564000 is a 3-pole fuse block designed for DIN rail mounting, rated for 50 A at 600V with cartridge fuse compatibility. This component is classified as obsolete, making identification of suitable substitute parts essential for system maintenance and component replacement in existing installations.

The primary reason for identifying alternatives is the obsolete product status, which limits availability for future procurement and system upgrades. Substitute parts must maintain electrical and mechanical compatibility with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2564000 is determined by the following critical parameters:

• Current Rating: 50 A (must match exactly)
• Voltage Rating: 600V (must match exactly)
• Number of Circuits: 3 (must match exactly)
• Mounting Type: DIN Rail (must match exactly)
• Fuse Type: Cartridge (must match exactly)

The substitute part 2560004 meets all critical electrical parameters. However, the fuse size differs: the substitute accommodates 14mm x 51mm cartridges, whereas the original accepts 10mm x 38mm cartridges. This difference reflects a design evolution in the product line and requires verification of fuse availability and mechanical fit within the installation environment.

Parameter Comparison

Engineering Selection Recommendations

The 2560004 is an active product with ROHS3 compliance, providing a path forward from the obsolete 2564000. Both components share identical electrical ratings (50 A, 600V, 3-circuit configuration) and DIN rail mounting compatibility.

Selection of the 2560004 as a substitute requires confirmation that the larger fuse cartridge size (14mm x 51mm versus 10mm x 38mm) is compatible with the mechanical envelope of the installation. The change in fuseholder type from block to holder and the unspecified termination style of the substitute necessitate physical verification against the original installation requirements.

Frequently Asked Questions (FAQ)

Q: Can the 2560004 directly replace the 2564000 in an existing installation?

A: Electrical compatibility is confirmed through matching current rating (50 A), voltage rating (600V), circuit count (3), and cartridge fuse type. Mechanical compatibility requires verification of the fuse cartridge size difference (14mm x 51mm versus 10mm x 38mm) and available space within the DIN rail enclosure.

Q: What is the significance of the fuse size difference between these parts?

A: The original 2564000 accepts 10mm x 38mm cartridges, while the 2560004 accepts 14mm x 51mm cartridges. This difference affects fuse procurement, physical fit, and may require enclosure modification. Confirm fuse availability and mechanical clearance before substitution.

Q: Are both parts compliant with current regulatory standards?

A: Both the 2564000 and 2560004 are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards.

Q: Why is the 2564000 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 2560004 represents the active product line continuation and is recommended for new installations and long-term availability.

Q: What should be verified before implementing the 2560004 as a substitute?

A: Verify mechanical fit of the larger fuse cartridge within the installation space, confirm availability of 14mm x 51mm fuse cartridges for your application, and validate that the termination method of the 2560004 is compatible with your system wiring.
