FAQs
Install the JSK-36 in the designated Bussmann Class J fuse holders, ensuring correct orientation because of the rejection-style design. Confirm the circuit is de-energized before replacement, align with the 2.38 in depth and 1 in width enclosure, and verify a 36 A rating and 200 kA interrupting capability at 600 Vac. Use the catalog JSK-36 to reference installation guidelines.
The JSK-36 combines fast-acting, current-limiting behavior with a 36 A rating and a 200 kA interrupting rating at 600 Vac, all within the Class J fuse family. This provides precise fault isolation, minimizes energy to the fault, and supports selective protection in motor controls and power distribution within industrial panels.
Yes, the JSK-36 is RoHS compliant, aligning with environmental and regulatory expectations. It is well-suited for machine controls, panel boards, and industrial drives where a 36 A fast-acting, current-limiting fuse is required to protect downstream electronics and motors while meeting sustainability criteria.
Key specifications include a 36 A current rating, 200 kA interrupting rating at 600 Vac, fast-acting current-limiting behavior, RoHS compliance, and a physical size of 2.38 in length, 1 in height, and 1 in width with an 8.2 lb weight. The catalog number is JSK-36 and the UPC is 051712630115.
