Abb MLA61 Main Lug Kit 600A

Product Description

The ABB MLA61 is a 600-amp main lug kit designed for use in electrical load centers and distribution panels. Main lug kits serve as the termination point for incoming service conductors when no main circuit breaker is required in the enclosure. This kit provides the lugs and hardware needed to land large-gauge feeders directly onto the panel busswork. It is typically installed by licensed electricians during new construction, panel replacement, or service upgrade projects where a separate upstream disconnect is already present.

This lug kit is suited for residential and light commercial electrical distribution applications. It is commonly used in load centers where the service entrance disconnect is located at a meter main, upstream panelboard, or dedicated disconnect switch. Installation requires proper conductor sizing to match the 600-amp rating and compliance with applicable NEC requirements for service entrance terminations.

Key Features

• 600-amp main lug rating for high-capacity service entrance or feeder termination
• Designed for use in load centers and distribution panels without an integral main breaker
• Includes hardware necessary for direct conductor termination to panel busswork
• Compact form factor sized to fit standard panel enclosures

Compatibility

Designed as an OEM-style main lug kit for ABB load centers and distribution panelboards rated for 600-amp main lug configurations.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the upstream service disconnect before beginning any work on the panel. Ensure incoming conductors are properly rated for the 600-amp load and terminated with the correct torque as specified in the panel enclosure documentation. Do not exceed the conductor gauge range specified for these lugs.
