High-energy protection translates to reduced downtime and lower replacement costs; with 80 kA per phase and a 200 kAIC short-circuit rating, equipment stays safeguarded during severe surge events, enabling uninterrupted production. This translates to measurable reliability gains and longer service life for connected loads in demanding industrial environments, including direct bus mounted panel boards PRL1a, 2a, 3a, and 3e. Integrated audible alarms with a silence button provide immediate fault visibility to operators, while the surge counter enables traceability for maintenance planning and compliance reporting. EMI/RFI filtering delivering up to 50 dB attenuation from 10 kHz to 100 MHz reduces noise on control signals, improving PLC and drive performance in noisy factory floors. The internal mounting design saves space, simplifies wiring, and reduces installation time, helping projects stay on schedule and within budget. Compatibility with 50/60 Hz systems and a 277/480 V rating supports widespread industrial deployment with minimal reconfiguration. The 15-year warranty adds long-term cost certainty, while UL 1449 Listed certification reinforces safety compliance. Direct bus mounting and compact dimensions provide asset-light installation for modernized facilities seeking scalable surge protection.
