Equivalent & Substitute Parts for T30200-3C

Part Overview

The T30200-3C is a fuse block cartridge designed for 200 A circuits at 300V, manufactured by Eaton - Bussmann Electrical Division. This component is classified as obsolete, making identification of suitable alternatives essential for ongoing maintenance and system design applications. The T30200-3C operates as a 3-circuit chassis mount fuseholder compatible with Class T fuses, utilizing cartridge-style fuse elements with box lug termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the T30200-3C is determined by strict equivalence across the following critical parameters:

• Current Rating: 200 A (exact match required)
• Voltage Rating: 300V (exact match required)
• Number of Circuits: 3 (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Termination Style: Box Lug (exact match required)
• RoHS Compliance: RoHS Compliant (maintained)

The TM30200-3CR qualifies as a substitute based on matching all critical electrical and mechanical parameters. While the fuse type differs (bolt down versus cartridge) and the compatible fuse series changes (JJN versus Class T), the fuseholder block itself maintains functional equivalence for the specified circuit protection application.

Parameter Comparison

Engineering Selection Recommendations

The TM30200-3CR is the designated substitute for the obsolete T30200-3C. Both components maintain identical electrical ratings (200 A, 300V, 3-circuit configuration) and mechanical mounting specifications (chassis mount with box lug termination). The TM30200-3CR holds active product status, ensuring continued availability and manufacturing support.

Selection of the TM30200-3CR requires verification that the system design accommodates bolt-down fuse elements (JJN series) in place of cartridge fuses (Class T series). This substitution is appropriate for applications where the fuse holder block specifications are the primary design constraint and fuse element compatibility can be addressed through system-level component selection.

Both parts maintain RoHS compliance, supporting regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the TM30200-3CR directly replace the T30200-3C without any modifications?

A: The TM30200-3CR matches all critical fuseholder specifications (current, voltage, circuit count, mounting, and termination). However, the fuse element type differs: the T30200-3C uses Class T cartridge fuses while the TM30200-3CR uses JJN bolt-down fuses. System design must accommodate this fuse type change.

Q: What is the primary reason for substituting the T30200-3C?

A: The T30200-3C is classified as obsolete. The TM30200-3CR provides an active, currently manufactured alternative with equivalent electrical and mechanical performance.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant. No compliance disadvantage exists in selecting the TM30200-3CR.

Q: Does the difference in fuse type affect the fuseholder block installation?

A: The fuseholder block installation remains identical. The difference in fuse type (cartridge versus bolt-down) affects only the fuse elements selected for the application, not the mounting or electrical connection of the fuseholder itself.

Q: What packaging options are available?

A: The T30200-3C is supplied in standard packaging. The TM30200-3CR is available in bulk packaging.
