70 A rating aligns with standard protection schemes for control circuits, enabling precise coordination with upstream breakers and selectors. Business impact: correct current rating minimizes nuisance trips and optimizes protection coordination with upstream devices. Application: ideal for control panels, MCCs, and equipment with moderate current draw. The JKS-70 is a fast-acting, current-limiting Class J fuse, which limits fault energy during a short circuit. Business impact: reduces fault impact on wiring insulation and connected components, shortening repair time. Application: supports safe equipment shutdown and improved process uptime in high-demand environments. The fuse offers a 200 kAIC interrupt rating at 600 Vac, providing high fault-current capability. Business impact: ensures reliable disconnection under bus faults, protecting conductors and devices. Application: suitable for panelboards and motor circuits where fault currents can spike. Bolted blade end x bolted blade end connections provide robust, install-friendly terminations. Business impact: faster, more secure field mounting with lower torque variability. Application: compatible with Bussmann series JKS fuses and standard industrial blade contactors. Compliance and packaging—CE Marked, RoHS Compliant, Standard packaging of five units per box. Business impact: regulatory compliance and predictable inventory management reduce rework and procurement costs. Application: global manufacturing environments requiring RoHS materials and CE conformity. Compact dimensions support panel space efficiency. Feature: 4.63 in length, 1.13 in width, and 0.29 lb weight per unit. Business impact: easier installation in crowded panels and predictable ease of replacement during maintenance.
