AMP-TRAP®–Form 101 A25X SEMICONDUCTOR PROTECTION FUSES A25X Amp-trap® Form 101 Semiconductor Protection fuses were designed for heavy duty rectifiers such as those used in the electro-chemical industry. Originally designed for diode protection, A25X fuses have been particularly reliable in heavy duty applications of many types. Note: Recommended as replacement fuses only Features / Benefits ➤ Low l2t minimizes damage to protected component on short circuit ➤ Controlled arc voltage reduces stress to circuit components during fuse clearing ➤ Choice of mounting types helps in equipment design Ratings ➤ AC: 10-30A 300VAC, 50kA I.R. 35-60A 250 VAC, 100kA I.R. 70-800A 250VAC, 10,600 A I.R. 1000-4500A 250VAC Approvals ➤ UL Recognized Component ➤ AC: UL Guide No. JFHR2 (10-250A) HIGHLIGHTS: ➤ APPLICATIONS: ➤ Fast Acting ➤ Current Limiting 2 ➤ Low l t ➤ Indicator Options Available Protection of 250 volt heavy duty rectifiers and similar heavy power supplies Catalog Numbering System Amp-trap® Fuse Rated Volts - 250 Style Amperes* A 25 X 600 1 4 128 A 25 X 600 - 4 TI Single Pole Fuse Blocks for A25X Fuses FUSE AMPERE RATING 1-30 31-60 61-100 101-200 201-400 401-700 FUSE BLOCK CATALOG NUMBER 20306 P243G P243 P243 P243G P243G Mounting Types* Ferrule Blades, bolt-in Hockey puck, bolt-in Integral Blown-Fuse Indicator Trigger Indicator Trigger Actuator TI TA * For ampere ratings and types not listed, consult the factory.
