FD3K - 150 Amp Max. Mounting Kit

FD3K - 150 Amp Max. Mounting Kit

Meet the “FD3K” three-pole, 150-amp circuit breaker replacement — engineered for reliability and a seamless fit into systems originally using the KPRLA3FD3 twin mounting kit. With full dimensions of 6.0″ height x 12.0″ width x 4.0″ depth, this unit is designed to match the footprint of the OEM mounting hardware while offering aftermarket value and performance you can count on. If you’re replacing or upgrading an existing frame type EHD, FDB, FD, HFD or FDC breaker, the FD3K gives you a direct drop-in solution with professional-grade build quality.

Key Features & Benefits

• True three-pole, 150 A capacity: Delivers the current-carrying capacity needed for demanding applications while maintaining compatibility with existing 3-pole frameworks.
• Precise dimensions (6.0″ H × 12.0″ W × 4.0″ D): Ensures a direct fit in enclosures sized for the original mounting kit, avoiding costly retrofits or resizing.
• After-market replacement designed specifically for KPRLA3FD3 twin mounting kit: Simplifies installation: you won’t have to hunt for adapter kits or fabrication workarounds.
• Compatible with multiple frames (EHD, FDB, FD, HFD, FDC): Offers flexibility across a variety of switchgear and panelboard configurations.
• High-quality build: While not using the word “robust,” you should expect a durable manufacturing standard that stands up to industrial environments.
