Bussmann PON50 Midget Fuse Time-Delay 50A 250V AC Non-Indicating
A time-delay midget fuse rated 50 A at 250 V AC with a 10 kA interrupt rating and cylindrical fiberglass body
- Product typeFuses & Accessories
- Time-delay operation handles motor-start surges without nuisance opening
- 50 A rating at 250 V AC suits heavy-duty branch circuits
- 10 kA interrupt rating at 250 V AC clears high fault currents safely
- Dual-element construction provides both overload and short-circuit protection
- Fiberglass body 76.2 mm long by 20.6 mm diameter fits standard midget fuse clips
Fuse Specification
The Bussmann PON50 is a cylindrical time-delay fuse rated for 50A at 250V AC. It suits industrial control panels and motor circuits that need overcurrent protection without nuisance tripping during startup surges.
Interrupt Rating
The single specification that determines fit is the 10kA interrupt rating at 250V AC. Systems with available fault current above this level require a higher-rated fuse, while lower ratings may not clear faults safely.
Installation Notes
The fuse body measures 76.2 mm long and 20.6 mm in diameter with fiberglass construction. It fits standard midget fuse clips; verify clip spacing and voltage rating match before inserting. The non-indicating design means a visual check or multimeter test is needed after a fault to confirm the element has opened.

Questions about this item
What does the 50 A rating mean once the fuse is installed in a circuit?
It allows continuous current up to 50 A and will open on sustained overloads while tolerating brief inrush currents thanks to its time-delay design.
How does the 250 V AC rating and 10 kA interrupt capacity limit where this fuse can be used?
It is rated for circuits up to 250 V AC and can safely interrupt fault currents up to 10 kA at that voltage.
What physical space and mounting style does the 76.2 mm by 20.6 mm cylindrical body require?
It fits standard midget fuse clips or blocks spaced for a 76.2 mm long, 20.6 mm diameter cylindrical body.
