FAQs
U4042230MCC is designed for surface mounting in 1Ø/3W meter configurations. It utilizes 4 jaws and a single position with ring connections, which integrates with continuous rating meter socket jaws and offers compatibility for ring vs ringless metering setups. This streamlines installation in B‑Line meter racks and reduces field wiring complexity, helping to accelerate commissioning and serviceability.
The unit provides a 320 A amperage rating with a 22 kAIC interrupt rating, meaning it can safely interrupt short‑circuit currents up to 22 kiloamps. This level of protection helps prevent equipment damage in fault conditions and minimizes risk to personnel. These specs align with typical commercial and industrial metering applications, delivering reliable protection for feeders and meters.
Yes. The U4042230MCC is built for heavy‑duty meter installations in industrial, commercial, and utility‑connected facilities. Its galvanized steel construction and EUSERC approval make it appropriate for outdoor or indoor environments where robust protection and regulatory compliance are required. The 1Ø/3W configuration is particularly applicable to single‑phase meter sites with compact panel layouts.
This model is UL listed and EUSERC approved, with a corrosion‑resistant galvanized steel body and ANSI 61 gray finish. These certifications ensure compliance with safety and utility interconnection requirements, enabling easier approvals from utilities and reduced project risk. The certifications also support consistent performance in demanding industrial environments.
Installation benefits include faster mounting due to surface‑mount design, ring and jaw compatibility for flexible wiring, and straightforward upgrade paths with standard meter jaws. ROI advantages come from reduced field labor, decreased downtime during installation or maintenance, and longer service life thanks to durable materials and protective finishes, all while maintaining regulatory compliance.
