## **Features:** - Provides 10X better current limitation to help prevent equipment damage caused by short-circuit events. - 200kA Interrupting rating complies with NEC[®] Section 110.9 for today's large capacity systems. - Fast-acting fuse helps prevent equipment damage caused by short-circuit events. - Small, space-saving fuses provide a high degree of current limitation on short-circuits for excellent component protection. - Ideal for critical industrial or commercial applications that have specific current limitation requirements. ## **Recommended Fuse Blocks** |**Amps Rating**|**1-Pole**|**2-Pole**|**3-Pole**| |---|---|---|---| |1-30|T60030-1_|T60030-2_|T60030-3_| |35-60|T60060-1_|T60060-2_|T60060-3_| |70-100|T60100-1_|T60100-2_|T60100-3_| |110-200|T60200-1_|—|1B0089| |2225-400|T60400-1_|—|—| |450-600|T60600-1_|—|—| For additional information on the 600 volt Class T fuse blocks, see Data Sheet # 1116.
