High-current capability and versatile metering configuration provide robust protection with a compact footprint. This reduces enclosure size and wiring complexity, delivering faster project turnover and lower installation costs. Ideal for commercial and light industrial meter installations needing 200 A, 22 kAIC, four jaws, MCB, and ring mounting to support reliable service connections. UL-listed protection with EUSERC approval ensures regulatory alignment and utility acceptance. This reduces procurement risk and simplifies commissioning for facilities subject to utility metering requirements. Used in new builds or retrofit projects where code compliance and utility buy-in are non-negotiable. Steel construction with ANSI 61 gray paint offers durable protection in indoor/outdoor environments, minimizing maintenance and repaint needs in dusty or humid environments. Surface-mount design with 1Ø/3W configuration supports easy integration into standard enclosures, speeding wiring and reducing field modification costs. Test block included for straightforward commissioning, with Eaton documentation guiding ring vs ringless metering decisions. Precise dimensions and a manageable weight enable predictable enclosure planning and safer handling during installation.

FAQs
The 224 MTBH MS45 is designed for meter mounting in electrical enclosures and supports 1Ø/3W service with four jaws, ring mounting options, and #6-250 MCM conductors. It integrates with Eaton B-Line mounting systems, enabling straightforward retrofits or new builds in commercial and light industrial settings.
A 22 kAIC interrupt rating indicates the device can safely interrupt high fault currents typical of commercial and light industrial feeders. This reduces the risk of arcing or equipment damage during faults, improving system reliability and protection for metering enclosures and upstream distribution equipment.
Yes. The unit is UL-listed and has EUSERC approval, confirming compliance with safety standards and utility-acceptance requirements. This simplifies procurement for utilities and streamlines commissioning on projects requiring metering equipment that meets utility codes.
For surface-mounted installations, ensure compatible enclosure dimensions are available and that conductors up to 250 MCM can be landed in the four-jaw block. The unit’s steel construction and ANSI 61 gray finish support indoor environments, with a 200 A rating and 22 kAIC capability to match typical panel layouts.
Specifying Eaton B-Line meter breakers provides regulatory alignment (UL listing, EUSERC), reliable protection for metering circuits, and a compact, easy-to-install solution that reduces project risk, speeds commissioning, and lowers long-term maintenance costs in commercial and light industrial facilities.
