**Special Application Fuses** PICO[®] 259 Series Safe-T-Plus Fuse for Hazardous Locations
## PICO[®] 259 Series Safe-T-Plus Fuse
## **Ro** ~~**HS**~~
## ~~**Description**~~
The Safe-T-Plus 259 Series offers a range of encapsulated fuses designed to enable greater safety for operating electronic equipment within potentially explosive environments. Originally designed to serve the needs of gas plants, petrochemical and processing industries, these fuses are certitifed for use within intrinsically safe apparatus with ATEX and IECEx certifications.
The fuse design and its encapsulant are suitable for use in intrinsically safe appartatus and associated apparatus for voltage not exceeding 125V rms (190V peak).
