89128646SP

Overview

The Hoffman Enclosures Inc. part number 89128646SP is a fuse component designed for electrical protection within industrial enclosure systems. It is specified as a 10A, 500V slow-blow fuse with physical dimensions of .25 inches by 1.25 inches. This component serves as a critical safety element to prevent circuit overloads and short circuits in associated electrical panels.

Feature Summary

• Provides slow-blow time-delay protection against transient current surges
• Rated for 500V operation to ensure compatibility with standard industrial voltage levels
• Features a compact .25 x 1.25 inch form factor for space-constrained mounting

Applications

• Industrial electrical panel protection
• Motor control circuit safeguarding
• Power distribution unit integration

Procurement Notes

Verify the specific voltage rating and current capacity requirements against the target circuit design before procurement. Confirm that the slow-blow characteristic aligns with the load profile to prevent nuisance tripping during normal startup conditions. Ensure physical dimensions match the existing fuse holder specifications within the enclosure assembly.

Selection Notes

Select this component when a time-delay response is required to accommodate inrush currents typical of motor loads or transformer connections. The 500V rating ensures suitability for higher voltage industrial applications compared to lower-rated alternatives. Consider the physical size constraints of the mounting location to ensure proper fit within the designated fuse block.

Part Context

This fuse is part of the Hoffman Enclosures product ecosystem, which specializes in electrical enclosures and thermal management solutions.
