FAQs
CVX050-240H is designed for three-phase power networks at 240, 480, and 600 V. It fits standard industrial panels without requiring special mounting hardware, and its compact 3.55 in L by 4.75 in W by 5.67 in H footprint keeps panel space manageable. Verify enclosure opening dimensions, clearance for wiring, and panel busbar spacing before retrofits to avoid obstruction.
The CVX050-240H provides a 50 kAIC surge energy handling capacity, meaning it can absorb large transient events without compromising protective performance. In practice this reduces the risk of protector failure during storm-level surges or switching transients, protecting downstream PLCs, drives, and relays. Its three-phase design ensures balanced protection across line-to-line and line-to-ground paths.
Ideal for industrial motor control centers, process equipment, and data-center peripherals that run on 240/480/600 V three-phase power. The device's 640 N-G operating voltage and UL 1449 certification support critical loads in automation systems, packaging lines, and machine controls. It performs well in facilities with mixed voltage rails and frequent transient events.
This unit carries UL 1449 certification, indicating compliance with essential safety and performance standards for surge protective devices. While CE and IP ratings are common references, UL 1449 certification at minimum ensures protection against transient voltages in industrial environments. Always verify regional regulatory requirements and confirm local code adoption for your installation.
Deploying CVX050-240H reduces unplanned downtime by limiting surge-related equipment damage, extending service life for drives and PLCs, and lowering maintenance frequency. The five-year warranty adds long-term protection, while compact installation reduces labor costs during retrofits. The result is lower total cost of ownership and faster project amortization in high-availability production lines.
