FP400 Fuse Cartridge Equivalent & Substitute Parts

Part Overview

The FP400 is a 10A 600VAC ceramic fuse cartridge manufactured by Amprobe, supplied in a 4-pack configuration. This component is designed for overcurrent protection in electrical circuits rated up to 600 volts AC. Finding equivalent substitute parts is necessary when the original FP400 becomes unavailable or when bulk packaging options are preferred for inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FP400 is determined by the following critical electrical and mechanical parameters:

• Current Rating: 10A (must match exactly)
• Voltage Rating - AC: 600 VAC (must match exactly)
• Fuse Type: Cartridge (must match exactly)
• Physical Form Factor: Ceramic cartridge construction

The substitute part 69032 (Klein Tools, Inc.) meets all these criteria. It is rated for 10A at 600 VAC and is constructed as a ceramic cartridge fuse. The 69032 additionally carries a 600 VDC rating, which exceeds the AC-only requirement of the FP400 and does not disqualify it as a substitute. The primary difference is packaging: the FP400 is supplied in a 4-pack, while the 69032 is supplied in bulk configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the FP400 and 69032 are active products with current inventory availability. Selection between these parts should be based on the following factors:

FP400 (Amprobe): Select when 4-pack packaging is required for standard inventory replenishment or when Amprobe brand specification is mandated.

69032 (Klein Tools, Inc.): Select when bulk packaging is acceptable or preferred for high-volume applications. The additional 600 VDC rating provides broader application flexibility without compromising AC circuit protection performance.

Both parts are suitable for direct substitution in 10A 600VAC cartridge fuse holder applications. No additional testing or verification is required when switching between these parts, provided the fuse holder is compatible with the cartridge form factor.

Frequently Asked Questions (FAQ)

Q: Can the 69032 directly replace the FP400 in my circuit?

A: Yes. Both parts are 10A cartridge fuses rated for 600 VAC. The 69032 requires a fuse holder, as does the FP400. Substitution is valid for all 10A 600VAC applications.

Q: What is the difference between the FP400 and 69032?

A: The primary difference is packaging. The FP400 is supplied in a 4-pack; the 69032 is supplied in bulk. The 69032 also carries a 600 VDC rating in addition to its 600 VAC rating. Both are ceramic cartridge fuses with identical AC electrical specifications.

Q: Does the 600 VDC rating on the 69032 affect its use in AC circuits?

A: No. The 600 VDC rating is an additional capability that does not impact AC performance. The 69032 is fully suitable for 600 VAC applications.

Q: Are there any compatibility issues with fuse holders?

A: Both the FP400 and 69032 are standard cartridge fuses. Compatibility depends on the fuse holder design. Verify that your holder accepts the cartridge form factor specified for these parts.

Q: Which part should I order for new installations?

A: Either part is acceptable. Choose based on packaging preference and availability. The FP400 4-pack is suitable for smaller quantities; the 69032 bulk option is suitable for larger deployments.
