Feature → Business Impact → Application: The U40411230MC uses a 320 A amperage rating with a 22 kAIC interrupt rating, delivering strong fault withstand capabilities that reduce the risk of damaging downstream equipment and downtime in commercial electrical rooms. This translates to improved system reliability and lowered maintenance costs in high-load metering installations. Application: suitable for main metering in 1Ø/3W configurations where capacity and protection matter. Feature → Business Impact → Application: Four-jaw mounting with 1Ø/3W wires and a single position ring jaw simplifies field engineering and wiring, cutting installation time and minimizing error-prone connections. Application: meter mounting scenarios in B-Line series assemblies where fast, secure connection is critical. Feature → Business Impact → Application: Galvanized steel with ANSI 61 gray finish provides corrosion resistance and durable aesthetics in demanding environments, reducing repainting needs and lifecycle costs. Application: surface-mounted metering enclosures exposed to moisture or industrial dust. Feature → Business Impact → Application: UL certification and EUSERC approval ensure regulatory compliance and eligibility for utility-funded or incentive programs, improving project acceptance and financing options. Application: code-compliant metering installations in new builds or retrofit projects. Feature → Business Impact → Application: The 6 in depth, 38 in height, and 30 in width with a 110 lb weight indicate a rigid, heavy-duty assembly designed for long service life and predictable field performance. Application: retrofit or new construction where durable, field-proven metering hardware is essential. Feature → Business Impact → Application: Surface-mount capability reduces mounting complexity and accelerates installation in restricted spaces, delivering faster project completion and reduced labor costs. Application: compact metering racks and wall-mounted distributions in commercial facilities.

FAQs
The U40411230MC is designed for B-Line series meter mounting and supports 1Ø/3W configurations with four jaws and ring jaw options. It is surface-mount compatible and UL listed, with a 320 A rating and 22 kAIC interrupt capacity, making it suitable for main metering in commercial and industrial panels.
A 320 A rating ensures the breaker can handle high-current metering loads typical in large facilities, while a 22 kAIC interrupt rating provides robust fault current interruption. Together, they enhance system protection, minimize conductor damage, and support compliant, reliable metering installations.
Yes. The U40411230MC carries UL certification and is EUSERC approved, meaning it meets recognized safety standards and utility-acceptable criteria for metering equipment, which can streamline project approvals and utility incentives.
Key considerations include its surface-mount design, four-jaw ring configuration, and single 1Ø/3W connection, which simplify wiring and mounting. The galvanized steel frame with ANSI 61 gray finish also reduces corrosion concerns in challenging environments, lowering maintenance intervals.
By combining high-capacity protection, durable construction, UL/EUSERC compliance, and ease of installation, the U40411230MC reduces field rework, extends service life, and accelerates commissioning, delivering measurable cost savings over the life of the installation.
