These fuses are ideal as the main fuse protection for panelboards, load centers and meter stacks. BENEFITS: • No intentional time-delay; opens quickly on overload. • Extremely current-limiting silver link construction; provides superior short-circuit component protection. APPLICATIONS: • Recommended for protection of non-inductive loads, such as lighting and resistance heating circuits. • Use to protect lower interrupting rating circuit breakers when series rated with Class T fuses. • For motor protection, size at 300% FLA which provides short circuit protection only. 22 Voltage Rating: TJN - 300VAC, TJS - 600VAC Ampere Rating: TJN: 1 - 1200 Amps TJS: 1 - 800 Amps Interrupting Rating: 200,000 RMS Symmetrical Amps Current Limiting: Class T Fuse Agency Approvals: UL Listed, Class T, Guide JDDZ,, File E162363 CSA Certified HRCI-T per C22.2, No. 248.12, LR700489 Self-Certified Ratings: Voltage Rating: TJN (15-600) TJN (601-1200) TJS (15-400) Interrupting Rating: TJN (15-600) TJN (601-1200) TJS (15-400) 160VDC 170VDC 300VDC 20,000 Amperes DC 100,000 Amperes DC 10,000 Amperes DC RECOMMENDED FUSEBLOCKS: Refer to page 138 in this catalog.
