FAQs
Installers should mount the unit in a suitable enclosure with adequate clearance for airflow and heat dissipation. Connect conductors to the internal terminal block to minimize wiring and ensure proper labeling. Verify conduit entries, torque settings, and enclosure integrity according to UL 1449 guidelines for a safe, compliant installation.
100 kA per phase means the device can safely absorb high-energy transient currents on each phase without degrading protection. This capability reduces the likelihood of device failure during severe surges and helps protect downstream equipment such as drives, transformers, and controllers from transient events.
Yes. Its UL 1449 listing, NEMA 4 enclosure, and 120/240V split-phase compatibility make it suitable for protecting critical loads in data centers and manufacturing facilities. The 100 kA per phase rating provides robust protection for sensitive electronics, reducing downtime and maintenance costs in uptime-critical environments.
The device is UL 1449 listed and features a NEMA 4 enclosure, ensuring safety, weather resistance, and suitability for demanding environments. These certifications simplify procurement, support regulatory compliance, and help meet project-specific safety and reliability requirements during audits and inspections.
Integration with Power Xpert SPD enables coordinated protection across devices, centralized monitoring, and streamlined maintenance.
