CB1451-1 Equivalent & Substitute Parts

Part Overview

The CB1451-1 is a fuse holder manufactured by Altech Corporation, designed for 14mm x 51mm cartridge fuses with a 50 A current rating at 600V. This component is mounted on DIN rail with vertical orientation and screw terminal connections. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CB1451-1 is determined by compatibility across the following critical parameters:

• Fuse size accommodation (14mm x 51mm cartridge format)
• Current rating capacity (50 A minimum)
• Voltage rating (600V or higher)
• DIN rail mounting compatibility
• Single circuit configuration
• Screw terminal termination

The substitute part 002560001 is identified as a manufacturer-recommended alternative. Substitution eligibility is based on the ability to accept the same fuse format and maintain electrical performance within the specified voltage and current parameters.

Parameter Comparison

Engineering Selection Recommendations

The CB1451-1 is obsolete and no longer in active production. The substitute part 002560001, also manufactured by Altech Corporation, is available in active production status with current inventory. Both components maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for electronic component applications.

The 002560001 operates at a higher voltage rating (690V AC/DC) compared to the original 600V specification, providing enhanced voltage margin in replacement scenarios. Both components are manufactured by the same supplier, ensuring consistency in design philosophy and quality standards.

Frequently Asked Questions (FAQ)

Q: Can the 002560001 directly replace the CB1451-1 in existing installations?

A: The 002560001 is the manufacturer-recommended substitute for the CB1451-1. Both are single-circuit fuse holders from Altech Corporation. Compatibility depends on the specific fuse format and electrical requirements of your application. Verify that the substitute accepts the same 14mm x 51mm cartridge fuse format used in your system.

Q: What is the significance of the higher voltage rating on the 002560001?

A: The 002560001 is rated for 690V AC/DC, compared to the CB1451-1 at 600V. This higher rating provides additional voltage margin and does not create incompatibility with 600V systems. The component remains suitable for applications operating at or below 600V.

Q: Are there any compliance differences between these parts?

A: Both the CB1451-1 and 002560001 maintain ROHS3 compliance and REACH unaffected status. No compliance barriers exist for substitution from a regulatory standpoint.

Q: Why is the CB1451-1 listed as obsolete?

A: The CB1451-1 has been discontinued by the manufacturer. The 002560001 represents the active production alternative for applications requiring single-circuit DIN rail-mounted fuse holder functionality.

Q: What packaging is available for the 002560001?

A: The 002560001 is available in bulk packaging, consistent with the original CB1451-1 packaging format.
