Selection Notes
The B24 111-100 is transformer-connected (1 A or 5 A CT secondary) rather than direct-wired, so it meters higher-current feeders that a direct-connect meter cannot handle safely. Single-tariff operation and one digital output keep it simple for basic active-energy billing without time-of-use rates. Choose a multi-tariff CT meter instead when tariff shifting or two-way communication is required.
