Feature: 100 kA per phase surge capability combined with a 200 kAIC interrupt rating. Business Impact: High-energy surge events are diverted away from sensitive equipment, minimizing downtime and extending the life of downstream controls. Application: Ideal for switchboards, busways, and panelboards in industrial facilities where reliability is mission-critical. The system design supports 50/60 Hz operation and a 240 V delta configuration, ensuring compatibility with high-leg delta installations. Content: This enables faster protection deployment in mixed-voltage environments and reduces total cost of ownership by limiting unplanned outages. Feature: EMI/RFI filtering delivering up to 50 dB attenuation from 10 kHz to 100 MHz. Business Impact: Cleaner power for PLCs, drives, and HMI systems translates to fewer control faults and more consistent automation performance. Application: Suitable for manufacturing lines and process controls where electrical noise compromises precision. Feature: Internal integrated mounting and compact footprint. Business Impact: Simplified installation reduces labor time and risk of miswiring, enabling faster commissioning and fewer field errors. Application: Works with standard enclosures and existing busway layouts in switchrooms. Feature: Audible alarm with silence button and Form C relay contact. Business Impact: Immediate status visibility for operators and seamless integration with facility alerting or SCADA systems. Application: Critical for real-time monitoring and quick response to electrical events. Feature: Surge counter with rest button. Business Impact: Maintains a verifiable log of surge events for maintenance planning and compliance reporting. Application: Helpful for audits and performance trending in data centers or manufacturing lines. Feature: 15-year warranty and UL 1449 UL Listed certification. Business Impact: Long-term protection reduces replacement cycles and total cost of ownership while ensuring regulatory compliance. Application: Suitable for long-life protection in industrial environments, including panelboards and switchgear assemblies.
