LIMITRON (BUSSMANN) โ€” JKS-250 Fuse Reclaimed Part

The LIMITRON JKS-250 by BUSSMANN (Eaton) is a UL Classย J fast-acting, current-limiting fuse designed to protect rectifiers, inverters, feeders, and DC common-bus rails in UPS and power-electronic systems. This listing features reclaimed, continuity-tested units removed from decommissioned, fully functional equipment. test

Features

Fast-Acting, Current-Limiting:
LIMITRONยฎ element clears rapidly with low let-through Iยฒt to protect sensitive components (Classย J).

Compact Classย J Footprint:
Smaller than RK fuses for tight panels; knife-blade ends fit standard Classย J holders/blocks.

High Interrupt Ratings:
600ย Vย AC with 200ย kA AC interrupt rating and 300ย Vย DC with 100ย kA DC capability (typ.).

Reclaimed & Verified:
Each unit is continuity-tested and visually inspected; new Eaton BUSSMANN stock available by request.
