American Electrical 2561100 Fuse Block Equivalent & Substitute Parts

Part Overview

The American Electrical 2561100 is a single-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 equivalent substitute parts essential for system maintenance and component replacement in existing installations.

The 2561100 serves as a protective switching device in electrical distribution systems where cartridge fuses provide overcurrent protection. Due to its obsolete status, sourcing direct replacements requires evaluation of functionally equivalent alternatives that maintain electrical and mechanical compatibility with the original circuit design.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2561100 is determined by the following critical parameters that must remain constant:

• Current Rating: 50 A
• Voltage Rating: 600V
• Fuse Type: Cartridge
• Number of Circuits: 1
• Mounting Type: DIN Rail

The substitute part 2560011 maintains electrical equivalence through identical current and voltage ratings, cartridge fuse type, single-circuit configuration, and DIN rail mounting. However, the substitute employs a different fuse size specification (14mm x 51mm versus 10mm x 38mm) and is classified as a fuse holder rather than a fuse block. This distinction reflects a design variation within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

The 2560011 qualifies as a functional substitute for the 2561100 based on matching electrical specifications: identical 50 A current rating, 600V voltage rating, cartridge fuse type, and single-circuit DIN rail configuration. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

The primary distinction between these parts is the fuse size specification and component classification. The 2560011 is an active product, ensuring ongoing availability and supply chain continuity compared to the obsolete 2561100. Selection of the 2560011 as a replacement requires verification that the larger fuse cartridge size (14mm x 51mm) accommodates the physical space constraints of the installation and that the holder design integrates with existing terminal connections.

Frequently Asked Questions (FAQ)

Q: Can the 2560011 directly replace the 2561100 in an existing installation?

A: Both components share identical electrical ratings (50 A, 600V) and cartridge fuse compatibility. However, the fuse size differs: the 2560011 accepts 14mm x 51mm cartridges while the 2561100 accepts 10mm x 38mm cartridges. Physical space availability and terminal connection compatibility must be confirmed before installation.

Q: What is the difference between a fuse block and a fuse holder?

A: Both are cartridge fuse protection devices for DIN rail mounting. The classification distinction reflects design variations, but both function as single-circuit protective switching devices with identical electrical performance in this application.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 2561100 and 2560011 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance restrictions.

Q: Why is the 2561100 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 2560011, classified as active, represents the current equivalent offering from American Electrical for this functional category.

Q: What fuse cartridges are compatible with each part?

A: The 2561100 accepts 5AG cartridges (13/32" x 1-1/2" midget size, equivalent to 10mm x 38mm). The 2560011 is specified for 14mm x 51mm cartridges. Cartridge selection must match the fuse holder specifications exactly.
