UNIRAC LUGMLPE1 UMOUNT NXT MLPE & Lug Clamp Domestic Content

The Unirac LUGMLPE1 is a dual-function, rail-mounted clamp designed for the NXT UMOUNT and NXT Horizon rail systems. This innovative component combines an MLPE mount (for microinverters and power optimizers) with a grounding lug into a single SKU — simplifying installation, reducing parts count, and streamlining grounding and module-level power electronics attachment in one easy step.

Key Features & Benefits:

• Dual-Function Design: One part serves as both MLPE mount and ground lug, eliminating the need for separate components.
• Tool-Friendly Installation: Features a full-size ½” bolt head for consistent tooling across the NXT system. Twist-in design slides into the open rail channel and locks securely with a 90° turn.
• Integrated Bonding: Provides reliable electrical bonding and grounding compliant with UL 2703 requirements.
• Flexible Positioning: Can be placed anywhere along the rail without interfering with splices or other attachments.
• Domestic Content Ready: Supports projects qualifying for Domestic Content Bonus Credit incentives.
• Compatible & Efficient: Works seamlessly with NXT UMOUNT Standard and HD Rails. Pairs perfectly with Unirac’s E-BOSS wire management solutions.
