Panduit EDNF10-250FI-Q StrongHold™ Female Disconnect Terminal
The Panduit EDNF10-250FI-Q delivers contractor-grade wire termination for 12-10 AWG conductors in commercial electrical, security, and AV installations. This fully insulated nylon-bodied female disconnect accepts .250" × .032" quick-connect tabs—the industry-standard dimension for power supplies, relays, and terminal blocks in access control panels, fire alarm circuits, and low-voltage infrastructure. Tin-plated brass contact surfaces resist corrosion in mechanical rooms and plenum spaces where humidity and temperature swings degrade uncoated terminals. Supplied in 250-piece cartons with inner packs of 25, this SKU matches the volume requirements of multi-building projects and service contractor truck stock.
Key Features
- 12-10 AWG wire range – accepts 2.08-5.26 mm² stranded copper for typical low-voltage branch circuits
- .250" × .032" tab – mates with NEMA-standard quick-connect terminals on transformers, relays, and barrier strips
- Nylon fully insulated barrel – 600V-rated dielectric sleeve prevents accidental shorts in crowded junction boxes and panel interiors
- Tin-plated brass contact – maintains conductivity in high-humidity environments; compatible with copper and aluminum wire per UL standards
- Funnel-entry wire insertion – flared barrel accepts stranded conductors without pre-twisting, reducing prep time on ladder work
- Compatible with Panduit CT-series crimp tools (CT-100A, CT-200, CT-600-A, CT-1570, CT-2300/ST, CT-2500/L) – ensures proper compression and pull-out strength per UL 310 requirements
- UL Listed E78522 and CSA LR31212 – meets NEC Article 110.3(B) for labeled terminations in commercial occupancies
- Bulk contractor packaging – 250-piece carton with inner packs of 25 for inventory control and field distribution
The EDNF10-250FI-Q's nylon insulation extends past the crimp barrel to the tab seating area, maintaining a 600V voltage rating even when terminals are installed in tight quarters. This full-insulation design is required under NEC 300.3(C)(2) for bundled low-voltage conductors sharing J-boxes with line-voltage circuits—common in retrofit security installations where 12VDC access control wiring enters the same enclosure as 120VAC convenience outlets. The tin-plated contact finish prevents galvanic corrosion when terminating to dissimilar metals (copper wire to brass terminal blocks), a frequent failure mode in coastal or underground parking applications where chloride exposure accelerates oxidation. Panduit's funnel-entry barrel geometry accepts 7-strand and 19-strand conductors without strand breakage during insertion, reducing the callbacks that occur when installers must re-strip and re-crimp terminals that reject wire during the seating process.
Use the EDNF10-250FI-Q for access control door strikes (12-10 AWG is the standard wire size for 12VDC/24VDC mag locks and electric strikes per BHMA A156.23), fire alarm notification appliance circuits (NFPA 72 allows 12 AWG for NAC circuits up to 1,000 feet), and AV system power distribution where rack-mount equipment terminates to barrier strips or Wieland connectors. The .250" × .032" tab dimension mates directly with Honeywell/Ademco panel terminals, Altronix power supplies, and Potter relay bases—eliminating the adapter pigtails that add resistance and create service headaches when troubleshooting intermittent faults. The 250-piece carton ships in Panduit's subdivided inner trays, allowing foremen to issue 25-piece packs to individual technicians for job-site accountability without breaking down bulk inventory. For crimp quality assurance, pair this terminal with Panduit's CT-series ratcheting tools: the CT-100A for hand crimping at the work location, or the CT-2500/L hydraulic tool for production crimping when pre-assembling 100+ cable harnesses in the shop before a cutover weekend.
StrongHold terminals carry UL's clamping and temperature-rise certifications for both copper and aluminum conductors, giving specifiers a single SKU for mixed-metal terminations in solar combiner boxes and battery back-up circuits where aluminum feeder cables transition to copper branch wiring. The tin-plated finish also maintains contact integrity through thermal cycling—critical in outdoor CCTV camera junction boxes where daily temperature swings from -10°F to 120°F would degrade bare-copper terminals within two seasons. When the job requires code-compliant, corrosion-resistant, and tool-compatible female disconnects for 12-10 AWG circuits, the EDNF10-250FI-Q delivers the termination reliability that keeps service calls and warranty claims off your plate.
