Description
Electronic Time-Delay Fuse 4A 250V .25 Inch x .25 Inch x 1.25 Inch
Features
- Engineered with an advanced dual-element, slow-blow time-delay characteristic, the MDA-4-R temporarily tolerates brief, harmless current spikes without tripping. This intentional delay eliminates frustrating nuisance blown fuses caused by temporary motor inrushes or inductive surges, while still delivering strict overcurrent safety during sustained overloads.
- Constructed with a premium ceramic body rather than a standard glass tube, this model delivers superior thermal and structural integrity under stress. The rugged ceramic shell safely contains severe internal arcs, preventing physical fragmentation or catastrophic component failure within sensitive industrial control panels, power supplies, or HVAC instrumentation.
- Built to the universal 1/4-inch by 1-1/4-inch (6.35 mm x 31.75 mm) physical standard, this cartridge fuse slots perfectly into your established electrical infrastructure. It ensures effortless drop-in deployment across a broad variety of standard clip-style blocks, panel-mount fuse holders, and electronic hardware without demanding expensive or time-consuming modifications.
- Fully UL Listed and CSA Certified, the MDA-4-R is manufactured to strict global environmental and safety benchmarks, including lead-free RoHS standards. Deploying factory-certified components protects valuable downstream devices from damage and keeps your factory machinery or commercial facility entirely inline with national electrical code mandates.
