Five cylindrical glass fuses with metal end caps

Bussmann

Bussmann S506-5-R Glass Fuse 5A 250V 50A 5 Pack

SKU CH-TJEC-TADVX

A pack of five 5 A, 250 V AC time-delay glass fuses with a 50 A interrupt rating and 20 mm cylindrical body

  • 5 A, 250 V AC rating protects circuits reliably
  • Time-delay characteristic tolerates brief surges without nuisance blows
  • 50 A interrupt rating at 250 V AC handles fault currents safely
  • 20 mm x 5 mm glass body fits standard fuse holders
  • Pack of five gives ready spares for maintenance

Essential Circuit Protection

These glass tube fuses provide 5 A time-delay protection at 250 V AC for equipment that experiences brief inrush currents. The cylindrical 20 mm by 5 mm body fits standard holders used in automotive, generator and industrial control panels. Each pack contains five replacement links for maintenance or field spares.

Upgrade From Fast-Acting Links

Fast-acting fuses open on harmless start-up surges, causing nuisance trips on motors, transformers or power supplies. The S506 series adds a delay element so transient peaks pass while sustained overloads are interrupted at 50 A. The change is worthwhile whenever repeated resets or blown spares indicate the original fuse was too sensitive.

Steady-State Reliability

Under continuous load the single-element design runs at its rated current without premature aging. The glass body allows visual confirmation of element status during inspection. cURus, IMQ and MITI/JET recognition confirms compliance for equipment that must meet recognised safety standards.

Questions about this item

What fuse-holder dimensions match the 20 mm length and 5 mm diameter of this S506-5-R fuse?

It fits cylindrical holders that accept a 20 mm long by 5 mm diameter glass body, such as the HTB fuse-block series listed as compatible in the specifications.

How do I install these time-delay glass fuses without damaging the element?

Press each fuse straight into the holder until the metal end-caps seat firmly; do not twist or force the glass body, as the single-element design can crack under sideways pressure.

When should I replace a fuse from this 5-pack after it has blown?

Replace it immediately with another 5 A, 250 V AC time-delay fuse of the same 20 mm x 5 mm size and 50 A interrupt rating to maintain the original circuit protection.
