About this file

Written by GovTribe AI ·

This file contains a product specification document for EP.MERSEN AJT Reducer Fuses related to the Pinellas County School District's Theater Lighting Renovations project in Florida. The document outlines technical specifications for Class J time-delay power fuses designed to reduce current ratings without requiring temporary fuse reducer accessories. The fuses are available in amperage ratings from 125 to 400 amperes, with voltage ratings up to 600VAC and 500VDC, and are intended for applications including motor circuits, feeders, branch circuits, lighting, heating, transformers, control panels, and bus ducts. The specification document includes detailed dimensional information, catalog numbers for both single-pole and three-pole configurations, and recommended fuse block options. The Pinellas County School District is soliciting sealed electronic bids for the Theater Lighting Renovations project with a submission deadline of 4:00 p.m. on Friday, May 15, 2026, via the District's e-Procurement Portal.

The fuses specified are UL and CSA listed to standard 248-8 and IEC 269-2-1, featuring arc flash mitigation capabilities, high current-limiting properties, and optional mechanical indicators. Key product benefits include dimensional stability through fiberglass construction, fast arc quenching via high-grade silica filler, and metal-embossed identification for traceability. Catalog numbers are provided for amperage ratings ranging from 125/400A through 400/600A, with specific pole configurations available. Interested bidders are strongly encouraged to register and download bid documents through the OpenGov Procurement Portal at https://procurement.opengov.com/portal/pcsb to receive automatic notifications of any addenda or updates.
