Feature: All-in-one design combines metering and protection in a single enclosure, enabling a compact, integrated solution for residential service panels that reduces device counts and simplifies coordination with utility requirements. Impact: By eliminating separate meters and protective devices in many installations, field labor, wiring errors, and space consumption drop noticeably, accelerating project timelines and improving overall reliability. Application: This approach is ideal for new-build homes and retrofit projects where tight spaces, utility approvals, and fast commissioning are critical to on-time handover. Feature: 125A rating with a 22 kAIC interrupt rating delivers strong fault current handling and improved coordination with upstream protection devices. This rating supports service feeders in typical residential and light commercial applications. Impact: The higher interrupt rating reduces the risk of nuisance tripping during short-duration faults and enhances uptime for critical loads. Application: Particularly valuable in meter mains and service equipment in areas with elevated fault currents or challenging loading profiles. Feature: Aluminum bus connectors with four-jaw terminals and top/bottom feed provide robust, corrosion-resistant terminations that adapt to a range of installation configurations. Impact: Enhanced conductors and versatile feed options shorten installation time, reduce thermal stress on connections, and improve long-term reliability in harsh environments. Application: Especially beneficial for outdoor service panels, retrofit projects, and new builds where rugged performance and flexible routing matter. Feature: NEMA 3R enclosure with weather protection, combined with UL Listed certification and EUSERC approval, delivers utility-grade readiness for outdoor installations. Impact: This certification portfolio streamlines approvals, minimizes non-conformance risk, and supports a 10-year warranty, improving life-cycle cost of ownership. Application: Suitable for meter mains, outdoor service cabinets, and energy-management programs that require proven protection and regulatory acceptance.

FAQs

MBT48B125BTS supports versatile top and bottom feed connections with four-jaw aluminum bus, enabling flexible wiring routes in both new panel installs and retrofits. This design reduces cable clutter, shortens termination times, and helps installers maintain consistent torque and termination reliability in constrained spaces.
Yes. The unit is designed for single-phase 120/240 V residential service with a 125 A rating and a 22 kAIC interrupt capability, making it suitable for common residence metering mains and service equipment. Its all-in-one approach simplifies coordination with utility requirements and reduces footprint in the main service area.
MBT48B125BTS carries UL Listed certification and is EUSERC Approved, ensuring utility-grade acceptance. The NEMA 3R enclosure further supports outdoor installations. Together, these certifications reduce project risk, simplify approvals, and support long-term reliability across service panels and exterior metering applications.
The all-in-one design reduces the number of discrete devices, shortens wiring runs, and minimizes interconnection points, directly cutting install time and labor costs. For projects with tight panel footprints, the integrated solution frees valuable space while maintaining regulatory compliance and metering functionality.
The combination of UL/EUSERC compliance, a 10-year warranty, and reduced field labor translates to lower lifecycle costs and predictable maintenance planning. Utilities and contractors benefit from fewer field reworks, reduced inventory complexity, and improved asset reliability in service panels and outdoor installations.
