Key Parameters

Substitute Part Grouping Explanation

The TM30200-1CR qualifies as a functional equivalent based on the following critical parameters that determine substitutability:

• Current Rating: Both parts are rated for 200 A
• Voltage Rating: Both parts are rated for 300V
• Number of Circuits: Both parts provide 1 circuit
• Mounting Type: Both parts are chassis mount configurations
• Termination Style: Both parts use box lug termination
• RoHS Compliance: Both parts meet RoHS requirements
• Manufacturer: Both parts are manufactured by Eaton - Bussmann Electrical Division

The primary difference lies in the fuse type: the T30200-1C uses cartridge fuses (Class T), while the TM30200-1CR uses bolt down fuses (JJN series). Both mounting orientations are supported by the substitute part (horizontal and vertical), providing installation flexibility not specified in the original part.

Parameter Comparison

Engineering Selection Recommendations

The TM30200-1CR is the designated substitute for the obsolete T30200-1C. Both parts maintain identical electrical ratings (200 A, 300V) and mechanical mounting configurations (chassis mount, box lug termination). The TM30200-1CR holds active product status, ensuring ongoing availability and supply chain continuity. Both parts are RoHS compliant, meeting current environmental and regulatory standards. The transition from cartridge to bolt down fuse type represents a design evolution within the Eaton - Bussmann product line while preserving circuit protection functionality and current-carrying capacity.

Frequently Asked Questions (FAQ)

Q: Can the TM30200-1CR directly replace the T30200-1C in existing installations?

A: Yes. Both parts share identical electrical ratings (200 A, 300V), single-circuit configuration, chassis mount design, and box lug termination. The primary difference is the fuse type (cartridge versus bolt down), which affects only the fuse selection and installation procedure, not the block's electrical or mechanical compatibility.

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

A: The T30200-1C accommodates Class T cartridge fuses, while the TM30200-1CR accommodates JJN bolt down fuses. This difference determines which fuse products can be installed in each block. The electrical protection characteristics remain equivalent when using appropriately rated fuses for each block type.

Q: Why is the T30200-1C classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production. The TM30200-1CR represents the current product offering from Eaton - Bussmann for this application category, providing equivalent functionality with active manufacturing support.

Q: Are there any orientation restrictions for the TM30200-1CR?

A: No. The TM30200-1CR supports both horizontal and vertical mounting orientations, providing greater installation flexibility than the original T30200-1C specification.

Q: Do both parts meet current compliance standards?

A: Yes. Both the T30200-1C and TM30200-1CR are RoHS compliant, meeting current environmental and regulatory requirements for electrical components.
