Overview

The ABB MaxGard Interlocked Receptacle with Circuit Breaker (SKU: DBRF440730000) provides 400 Amp continuous current with a 300 Amp breaker trip rating for 3-phase, 4-wire systems at 250V, 60Hz. This interlocked design ensures power cannot be disconnected while energized, significantly reducing arc flash risk in industrial environments. The 3-pole, 4-wire configuration supports balanced load distribution for heavy machinery, data centers, and manufacturing plants. Rated for 250V operation, it integrates with existing 3-phase infrastructure while offering built-in overcurrent protection via the integrated 300A breaker. The MaxGard series is constructed with corrosion-resistant materials and a rugged enclosure for reliable performance in harsh conditions. Pre-wired breaker connections and an interlocked mechanism simplify installation and enhance operational safety. Compatible with standard 3P4W NEMA configurations, it meets UNSPSC 39121404 and is manufactured in the US.
