Voltage compatibility and control flexibility: The release operates from 110–127 VAC and 110–125 VDC, supporting common control circuits found in global plants. This dual-voltage capability reduces part variants in stock and enables rapid deployment across mixed-voltage panels, delivering immediate, predictable trips in Tmax T heavy-duty configurations. Installation and commissioning benefit from straightforward wiring and a compact form factor, cutting on-site labor and footnotes of panel integration. Configuration is loose or configurable, allowing tailored mounting to diverse panel layouts and minimizing rework during retrofits. The result is faster commissioning, reduced engineering time, and improved first-pass quality in project handovers. Standby readiness is enhanced by robust protection coordination with upstream devices, decreasing fault clearance times and improving overall system reliability.
