3 Amp 250Vac Fast Acting Fuse · Littelfuse 235003P
Fast-acting 5x20 mm glass cartridge fuse rated 3A at 250VAC for supplementary protection of appliance and electronic equipment circuits. Commonly used where sensitive components need quick opening on overload or short circuit; always match fuse size, amp rating, voltage rating, and speed to the original design.
What this product is for
This 5x20 mm fast-acting glass cartridge fuse is used for supplementary overcurrent protection inside appliance, utilization, and electronic equipment. It is intended to open quickly when current rises above the circuit's safe limit.
Use for
- Protecting sensitive electronic components and internal equipment circuits
- Replacing an existing 5x20 mm fast-acting fuse with the same ratings
- Appliance and control applications that call for a 3A, 250VAC glass cartridge fuse
Avoid for
- Branch circuit protection in place of a breaker or properly rated power fuse
- Replacing a time-delay fuse where inrush current is expected
- Any application where the original equipment requires a different ampere rating, voltage rating, or fuse characteristic
Best for
Electricians, maintenance teams, and OEM buyers who need a Littelfuse 235 Series fast-acting cartridge fuse in the standard 5x20 mm format for equipment repair or production use.
Installed in
Typically installed in fuse clips, fuse holders, or equipment boards designed for 5x20 mm cartridge fuses. Body size is 5 mm diameter x 20 mm length, approximately 0.20 in x 0.79 in.
Why this product exists
This fuse provides individual component or internal circuit protection where a fast-opening response is needed. Compared with slower time-delay fuses, a fast-acting fuse is commonly selected for circuits with lower inrush tolerance and more sensitive electronics.
Compared with similar products
Choose this fuse when the equipment specification calls for a fast-acting 5x20 mm glass fuse at 3A and 250VAC. Do not substitute it for a time-delay style unless the equipment manufacturer allows it. As a rule of thumb, fuse replacement should match the original ampere rating, voltage rating, physical size, and speed class. Actual suitability depends on equipment design and local code requirements.
