Recommended fuse blocks: Agency information UL® Recognized 15-300A, Guide JFHR2, File E56412 Features: • These fuses avoid needless openings from starting currents or surges • A fuse link which operates only on very high overloads or short-circuits • Thermal cutout functions on low overloads – the thermal cutout cannot operate quickly at any load, hence long timelag is obtained on high overloads of short duration • ACK-100 ACK-50 Fuse • • ACK-40 ACK-15 Test specifications • • ACK-10 This long time-lag also makes it unnecessary to use extra large size or over-size fuses Catalog number Block number Catalog number Block number ACK 10-30 4228 ACK 120-200 3569 ACK 35-60 3411 ACK 225-400 3578 ACK 70-100 2322 Dimensions - in (mm): A D B F C E G Catalog number Dimensions in inches and (mm) A B C D E F G ACK 10-30 2.5” (63.5) 0.375” (9.53) 0.500” (12.70) 0.250” (6.35) 0.557” (14.15) 0.588” (14.94) 0.031” (0.79) ACK 35-60 3.0” (76.20) 0.470” (11.94) 0.685” (17.40) 0.344” (8.74) 0.812” (20.63) 0.860” (21.84) 0.051” (1.30) ACK 70-100 3.5” (88.90) 0.547” (13.89) 0.750” (19.05) 0.312” (7.92) 1.062” (26.98) 1.15” (29.21) 0.050” (1.27) ACK 120-200 3.750” (95.25) 0.750” (19.05) 0.750” (19.05) 0.375” (9.52) 1.062” (26.98) 1.15” (29.21) 0.050” (1.27) ACK 225-400 3.750” (95.25) 0.610” (15.49) 0.750” (19.05) 0.312” (7.92) 1.062” (1.062) 1.125” (28.58) 0.050” (1.27) Note: 10-60 amp fuses use brass terminals and ferrules. 70-400 amp fuses use copper terminals and ferrules.
