HRC Fuse system, the latest and most versatile design, compact HRC Fuse and bases with current ratings from 6A to 630A with breakig capacity of 92 KA at 415 V AC. SALIENT FEATURES : Switching reliability : BL-NH-HRC Fuse Links are tested for switching reliability in complete range of application. They perfectly master low over currents with sufficient heat generation and medium short circuit currents with maximum pressure stressing. Cut of Characteristics : BL-NH HRC Fuse Links have a current limiting effect. They interrupt the short circuit current while it is increasing and do not allow the current to reach its peak value.
