Eaton Bussmann Type 74 telecommunication fuse BK/74H-4 60V CE
Part Number: BK/74H-4
Quick Summary
The Eaton Bussmann Type 74 telecommunication fuse provides fast-acting protection for low-voltage telecom circuits in control cabinets. Engineers wrestle with bulky protection devices that complicate spare parts logistics and extend maintenance intervals. It is CE marked, aligning with European safety standards and helping procurement managers meet regulatory requirements. Beyond compliance, its compact form, 60 V rating, and 4 A capacity support reliable protection with minimal footprint. This combination helps engineers reduce downtime and simplify stocking through a single, compatible Bussmann Series solution. Its non-indicating design also simplifies panel mounting in spaces with minimal maintenance routines. Designed for telecom racks, it integrates with standard protective devices, easing replacement during outages.

Eaton Specification Sheet - BK/74H-4
Fast-acting protection at 60 V and 4 A improves fault isolation and minimizes arc energy, reducing equipment damage and downtime in telecom racks. This translates to lower repair costs and quicker service windows, especially in control cabinets where space is tight. The compact 1.62 in x 0.42 in x 2.4 in footprint and 0.5 lb weight enable easy drop-in replacement within standard enclosures, improving install efficiency and inventory management. The non-indicating fuse reduces external wiring complexity and points to system-level monitoring for health checks, while still delivering reliable protection when paired with proper diagnostics. CE Marked compliance cuts regulatory risk for European projects, while cross-compatibility with Bussmann Type 74 catalogs ensures consistent sourcing. In practice, customers gain faster MTTR and streamlined procurement.

FAQs
For best results mount the BK/74H-4 in standard protective enclosures within control cabinets. Verify 60 VDC circuits align with the fuse's 60 V rating, and ensure adequate clearance for heat dissipation. Use compatible Bussmann Type 74 holders and follow Eaton datasheet guidance to avoid misfits.
The BK/74H-4 is a 60 V rated, 4 A fast-acting telecommunication fuse. It’s designed for low-voltage telecom circuits and 60 VDC protection in control panels, providing rapid fault clearing while maintaining system continuity for non-critical loads.
Yes, for many standard industrial environments, the fuse provides reliable protection while fitting in compact spaces. For harsh environments consider enclosure rating, ambient temperature, and additional protection since data specifies CE compliance but not IP/sil ratings.
BK/74H-4 is CE Marked, indicating compliance with European safety and performance standards. This helps meet regulatory requirements for European projects and supplier qualification, reducing risk in audits and cross-border procurement.
The fast-acting, compact BK/74H-4 minimizes failure energy and supports quick replacement in standard Bussmann catalogs. Its non-indicating design reduces component count and simplifies stocking, contributing to lower maintenance labor and shorter downtime during fault events.
