ERMS is an option for circuit breakers with electronic trip units and some fused switches.

Explanation:
ERMS relies on digital communication with protective devices to monitor, log, and manage their operation. Circuit breakers that have electronic trip units provide the needed electronic interface, data, and signaling for ERMS to connect, collect events, settings, and status. Some fused switches are designed with an electronic trip module or a compatible interface, so they can also be integrated with ERMS. Without an electronic trip unit or the appropriate interface, ERMS can’t function, which is why this option applies to devices with electronic trip units and to select fused switches.
