FAQs
The BK/74J-7-1/2 is designed with a compact form factor (1.62 in length, 0.42 in width, 2.4 in height) and standard packaging to support straightforward replacement in common telecom chassis and protection schemes. Its 60 V, 7-1/2 A ratings align with typical line-side protection requirements, helping ensure a reliable upgrade path without extensive rework.
The fuse provides a 60 V voltage rating and a 7-1/2 A current rating with fast-acting characteristics. This means it quickly interrupts excess current to safeguard telecom circuits such as line cards and network interfaces from overcurrent events, reducing the risk of equipment damage and network downtime.
Yes. The BK/74J-7-1/2 is CE Marked, indicating conformity with European safety standards. This makes it suitable for European installations and procurement programs that require CE compliance, while maintaining compatibility with standard Bussmann Type 74 telecommunication fuse specifications.
Consider the non-indicating nature of the fuse, which means status indication is not built into the fuse itself. Rely on system-level monitoring or fault indicators. Also account for the fuse’s compact dimensions and standard packaging to simplify stocking, replacement workflows, and compatibility with existing telecom protection arrays.
Specifying this fuse provides proven protection with a compact footprint and fast-acting response, reducing downtime after faults and limiting equipment damage. The CE mark supports multinational deployments, while the 60 V/7-1/2 A ratings align with common telecom power rails, enabling consistent procurement and easier maintenance across sites.
