Feature → Business Impact → Application: High surge rating of 100 kA per phase paired with a 200 kAIC short‑circuit rating provides robust defense against damaging transients, reducing equipment wear and unplanned outages for critical loads in switchboards and panelboards. Application: ideal for protecting 240 V delta (3W+G) distributions in industrial facilities. Feature → EMI/RFI filtering up to 50 dB from 10 kHz to 100 MHz reduces electrical noise, improving control sensitivity and data integrity for PLCs and drives. Application: suitable where precise control signals and communications reliability matter. Feature → Audible alarm with silence button and Form C relay contact improves proactive maintenance and remote monitoring; surge counter with rest button simplifies fault tracing. Application: supports scalable condition monitoring across panels. Feature → Internal integrated mounting and compact footprint (9.5 in x 5.4 in) enable easy installation in crowded switchgear spaces; 3.5 lb weight and 15-year warranty offer predictable service life and total cost of ownership. Application: fits retrofit and new build panel protection strategies. Feature → Broad compatibility with Switchboard, busways, and panelboards (PRL1a, 2a, 3a, 3e, 4) ensures plug‑and‑play integration with existing electrical infrastructure. Application: minimizes wiring complexity and downtime during installation.
