FAQs
BK/70N-10A is designed for telecom circuits requiring overcurrent protection in data centers, network cabinets, and field equipment. With a 125 VAC / 300 VDC rating and a 10 A current rating, it protects line cards, power supplies, and distribution blocks while keeping downtime minimal and maintenance predictable.
Install BK/70N-10A in standard fuse holders or compatible telecom panels using its compact footprint (1.63 in depth, 0.42 in width, 2.5 in height). Ensure circuit isolation before replacement, verify voltage ratings (125 VAC / 300 VDC), and confirm the 10 A current rating aligns with the protected load to avoid nuisance trips.
The BK/70N-10A provides 10 A amperage rating, 125 VAC and 300 VDC voltage ratings, and a 1 kAIC interrupt rating at 300 VDC, making it suitable for telecom protections that demand swift fault interruption without compromising adjacent equipment.
No. The BK/70N-10A is a non-indicating fuse, which means it does not visibly show when it has blown. In applications where status indication is required, pair it with remote monitoring or panel indicators to ensure reliability and quick fault identification.
BK/70N-10A carries CE Marked compliance, signaling conformity with European safety and environmental standards. This supports regulatory-ready procurement and helps meet regional electrical protection requirements for telecom equipment.
