FAQs
Yes. The LPS-RK-100SP-TP is a Class RK1 fuse designed to fit standard Bussmann RK1 holders and assemblies. Its tin-plated terminals and standard packaging simplify field replacement and stocking. For best results, select RK1 compatible bases rated for 600 V and 100 A, and verify that the installation footprint matches the 7.88 in length and 1.11 in width provided in the datasheet.
The fuse is rated for 100 A with an interrupt capacity of 100 kAIC at DC and up to 300 kAIC at 600 Vac. It supports voltage ratings of 600 V and 300 Vdc, making it suitable for both AC and DC protection in panel boards, drives, and DC buses within automation environments.
Ideal for motor control centers, drives, DC buses, and power distribution panels where inrush currents are common. The time-delay capability accommodates short surges without compromising protection, while the current-limiting feature minimizes fault energy and equipment damage during faults, improving uptime and reducing maintenance costs.
The fuse is RoHS compliant and carries the RK1 Class designation, aligning with Bussmann RK1 family standards. These attributes support regulatory environmental requirements and standardization across control panels, increasing procurement consistency and cross-model compatibility.
The time-delay, current-limiting design reduces nuisance trips, lowering downtime and extending equipment life. Standard RK1 form factor and tin-plated construction simplify replacements and stocking, delivering faster repair cycles and lower total cost of ownership for automation facilities across cyclical maintenance programs.
