High surge protection performance with 100 kA per phase and 200 kAIC interrupt rating provides fast, reliable clamping of transients, reducing risk of damage to motors, drives, and control electronics. This translates to fewer unscheduled outages and lower repair costs, especially in manufacturing lines and data centers where uptime is mission-critical. The 400Y/230V (4W+G) rating, together with 320 L-N, 320 L-G, 320 N-G, and 640 L-L operating paths, ensures safe compatibility with common 3‑phase distributions and simplifies wiring in panelboards such as PRL-C, enabling quick, error-free installations with right terminals and internal mounting. EMI/RFI filtering delivering up to 50 dB attenuation from 10 kHz to 100 MHz reduces noise on control networks, improving PLC and sensor performance and protecting sensitive electronics in process automation. Audible alarm with silence button, surge counter with rest button, and Form C relay contact provide proactive fault signaling and maintenance visibility without opening enclosures. Right terminals and integrated mounting streamline field wiring, cut commissioning time, and lower labor costs while ensuring reliable performance in industrial environments. These features collectively support long-term lifecycle value and compatibility with standard Eaton accessories and warranty replacement options.
