FAQs
The 217 MTBH MS45 supports a flexible jaw arrangement with 7 jaws and 1 position, including ring and ringless configurations. It is designed for ring-mount metering setups and works with 3Ø/4W systems. This versatility reduces retrofit costs and simplifies field installations by accommodating a range of common meter socket jaw types while preserving secure electrical connections.
A 22 kAIC interrupt rating provides higher fault current tolerance, protecting meters, feeders, and upstream equipment from catastrophic faults. In metering installations, this translates to increased reliability during short circuits or fault events, reduced transformer and conductor damage, and improved uptime for critical utility connections in commercial and industrial facilities.
Yes, the 217 MTBH MS45 is UL Listed and EUSERC Approved. UL listing confirms adherence to recognized safety standards, while EUSERC approval validates suitability for electrical utilities and utility metering applications. Together, these certifications streamline approvals, support code compliance, and reduce project risk for utility-grade metering installations.
The 217 MTBH MS45 is designed for 3Ø/4W configurations, ensuring proper phase connections and balanced protection. It uses a surface-mount method within a 3R enclosure, with dimensions that support standard mounting clearances in meter banks and panel boards. This combination simplifies site fit and minimizes enclosure modification requirements during installation.
The unit’s UL/EUSERC certifications, robust galvanised steel housing, and compact footprint contribute to faster installation and fewer field adjustments, reducing labor time and risk of rework. The 100 A rating with 22 kAIC protection lowers potential fault-related downtime, while durable finishes reduce corrosion-related maintenance, delivering a measurable return on investment over the equipment’s life cycle.
