High surge capability and robust protection are engineered to shield critical loads from damaging transients, delivering a measurable reduction in unplanned downtime. The 100 kA per phase surge current and 200 kAIC short-circuit rating translate into improved equipment longevity and lower maintenance costs for automation and manufacturing environments. A wide voltage range (200 V to 277 V) and 50/60 Hz compatibility ensure a single device supports diverse panel configurations, reducing spare-part inventory and accelerating commissioning in new or upgraded facilities. EMI/RFI filtering delivers up to 50 dB of noise attenuation from 10 kHz to 100 MHz, improving PLC, servo, and drive performance by minimizing electrical noise on control signals. An audible alarm with silence button, a Form C relay contact, and a surge counter with a rest button enable proactive maintenance and traceability, lowering the risk of undetected surges affecting production. Direct bus mounting compatibility with PRL1a, 2a, 3a, 3e panels simplifies installation, saving time and minimizing field wiring. The compact footprint (9.5 in × 5.4 in × 3.45 in) and 3.5 lb weight support easy integration in crowded switchgear enclosures, while the 15-year warranty provides long-term protection and total cost of ownership benefits.
