Ferraz Shawmut MPDB66021 Power Distribution Block 350A

Product Description

The FERRAZ SHAWMUT MPDB66021 is an open-style power distribution block designed for high-capacity electrical distribution applications. Rated at 350 amps and 1000 volts, this single-pole block is constructed from tin-plated copper, providing reliable conductivity and corrosion resistance in demanding environments. It features a 1-pole, 2-opening configuration with a box-to-box wiring arrangement, accepting wire sizes from 2/0 AWG down to No. 14 AWG on both the line and load sides. Licensed electricians and industrial maintenance technicians install this type of component in panel boards, motor control centers, and distribution enclosures where consolidating multiple branch conductors to a single source is required.

The MPDB66021 is suited for use in commercial and industrial electrical distribution systems where a compact, open-style block is needed inside an enclosure. Its box-to-box termination style makes it appropriate for installations where conductors enter and exit from enclosed wiring channels or junction boxes. The 1000-volt rating supports a broad range of industrial power distribution scenarios, and the 350-amp capacity accommodates high-load branch circuits typical in commercial panel and switchboard builds.

Key Features

• 350-amp continuous current rating supports high-load distribution circuits
• 1000-volt rating suitable for a wide range of industrial and commercial applications
• Tin-plated copper construction provides strong conductivity and corrosion resistance
• Open-style design for installation inside enclosures, panel boards, or motor control centers
• Accepts wire sizes from 2/0 AWG to No. 14 AWG on both line and load sides
• Box-to-box termination configuration for clean, organized wiring runs
• Single-pole, 2-opening layout simplifies branch circuit consolidation

Compatibility

Designed as an OEM-style replacement or new-installation power distribution block for commercial and industrial electrical enclosures requiring a 1-pole open-style block rated at 350 amps and 1000 volts with 2/0 to No. 14 AWG wire range.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before handling or terminating any conductors. Ensure the enclosure or panel board is rated to accommodate a 350-amp open-style distribution block before mounting. Verify that all conductor terminations are torqued to the terminal manufacturer specifications listed on the product or its documentation.
