Mersen MPDB67423 3-phase 310A Power Distribution Block

Product Description

The MERSEN MPDB67423 is a 3-phase, 310-amp power distribution block designed to split a single high-ampacity input feed into multiple branch output connections within an electrical panel or enclosure. It handles heavy-duty current distribution demands common in commercial and industrial electrical systems. Licensed electricians and panel builders install this component during service entrance work, motor control center builds, and main distribution panel construction. The block is rated for 310A continuous service across all three phases, making it suitable for high-load branch circuit distribution applications.

This power distribution block is used in commercial and industrial electrical installations where a central feed must be divided to multiple downstream circuits. Typical applications include motor control centers, switchgear panels, large electrical distribution boards, and industrial machine wiring enclosures. It ships 2 units per pack, providing a convenient pairing for balanced three-phase distribution setups or for stocking purposes in service shops.

Key Features

• 3-phase configuration supports balanced multi-phase power distribution
• 310A rating handles high-ampacity commercial and industrial loads
• Compact form factor fits standard electrical enclosures and panel cabinets
• Sold 2 per pack for efficient stocking and paired installation needs

Compatibility

Designed as an OEM-style power distribution block for use in 3-phase commercial and industrial electrical panels and enclosures requiring 310A input distribution capacity.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the panel or enclosure fully before mounting or wiring the distribution block. Verify conductor sizing and torque specifications per the manufacturer documentation and applicable NEC requirements before making terminations. Do not exceed the rated ampacity of the block on any phase.
