A high 100 kA per phase surge rating provides a robust shield for critical loads, dramatically reducing the risk of equipment damage and costly downtime in drives, PLCs, and motor circuits. This translates to longer equipment life and improved process reliability in manufacturing lines and infrastructure upgrades. The device is designed for 400Y/230V (4W+G) systems and supports 50/60 Hz operation, ensuring compatibility with common industrial power distributions and simplifying retrofits. Internally integrated features include a surge counter and a rest button, enabling fast fault diagnosis and proactive maintenance without disassembly, while the Form C relay contact provides straightforward integration with existing control and monitoring systems. EMI/RFI filtering achieves up to 50 dB attenuation from 10 kHz to 100 MHz, minimizing interference with sensitive automation devices and communications networks. Audible alarm with silence option reduces nuisance alarms in noisy plant environments, preserving operator focus for actual faults. The compact footprint and internal mounting simplify installation on Direct bus mounted panel boards PRL1a, 2a, 3a, and 3e, delivering reliable protection with minimal cabinet space, and the 15-year warranty supports long-term lifecycle cost reductions and predictable budgeting for maintenance teams.
