H25030-1C Equivalent & Substitute Parts

Part Overview

The H25030-1C is a single-circuit fuse block cartridge designed for chassis mount applications at 250V with a 30A current rating. This component is classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and redesign applications. The H250 series fuse block utilizes Class H(K) and Class R cartridge fuses with a standard 0.563" diameter by 2" length form factor and box lug termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the H25030-1C is determined by strict equivalence across the following critical parameters:

• Voltage rating: 250V
• Current rating: 30A
• Number of circuits: 1
• Fuse type: Cartridge
• Fuse size: 0.563" Dia x 2" L
• Mounting configuration: Chassis mount
• Termination style: Box lug
• Compatibility with Class H(K) and Class R fuses

The substitute part HM25030-1CR maintains electrical and mechanical compatibility with the H25030-1C across all specified parameters. The primary distinction is product status: HM25030-1CR is active and RoHS compliant, whereas H25030-1C is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The HM25030-1CR is the direct substitute for the obsolete H25030-1C. Both components are manufactured by Eaton - Bussmann Electrical Division and share identical electrical and mechanical specifications for 250V, 30A single-circuit cartridge fuse block applications.

Selection of HM25030-1CR is supported by:

• Active product status with ongoing manufacturer support
• RoHS compliance certification
• Identical voltage, current, and circuit configuration
• Matching fuse size and mounting specifications
• Equivalent termination and contact interface

The HM25030-1CR is suitable for direct replacement in existing designs and new applications requiring 250V, 30A single-circuit fuse block functionality with chassis mount configuration.

Frequently Asked Questions (FAQ)

Q: Can HM25030-1CR directly replace H25030-1C in existing assemblies?

A: Yes. Both components share identical electrical ratings (250V, 30A), circuit configuration (1 circuit), fuse type (cartridge), physical dimensions (0.563" Dia x 2" L), mounting method (chassis mount), and termination style (box lug). Direct mechanical and electrical substitution is supported.

Q: What is the significance of the product status difference?

A: H25030-1C is obsolete and no longer manufactured or supported by Eaton. HM25030-1CR is an active product with current manufacturing and technical support. For new designs or long-term supply requirements, HM25030-1CR is the appropriate selection.

Q: Does RoHS compliance affect compatibility?

A: RoHS compliance in HM25030-1CR indicates conformance to restriction of hazardous substances standards. This does not affect electrical or mechanical compatibility with applications designed for H25030-1C. RoHS compliance is an additional benefit for regulated environments.

Q: Are there packaging differences between these parts?

A: H25030-1C is specified with dash packaging notation. HM25030-1CR is supplied in bulk packaging. Packaging format does not affect component functionality or substitution suitability.

Q: What fuse types are compatible with these fuse blocks?

A: Both H25030-1C and HM25030-1CR are designed for use with Class H(K) and Class R cartridge fuses in the 0.563" Dia x 2" L form factor.
