Key Features and Characteristics
The XT7LU312EDFF000XXX: As an XT7L-D series MCCB, this breaker offers a 1200 A frame and is built for high-fault current environments typical in industrial switchboards and panelboards. The 'L' designation indicates a line-side connection configuration, while the 'D' suffix points to a specific trip unit variant optimized for distribution duty.
Applications and Environments
This MCCB is suited for main or feeder protection in industrial plants, commercial buildings, and infrastructure projects. It handles the high short-circuit currents found in transformer-fed distribution systems and supports selective coordination with downstream breakers for fault isolation.
