Phoenix Contact’s VALVETRAB-SQ surge protective devices (SPD) offer safe, reliable surge protection from 40,000A to 200,000A. The NEMA-style product series includes approximately 50 part numbers in three different mountable designs designated by CC (control cabinet), SP (sub-panel), and SE (service entrance) identifiers. The VAL-SQ CC Series offers an economical method of protecting electronic equipment in light commercial, light industrial and residential environments. It has 40,000A of surge current rating, and its compact design is appropriate for installation in a control cabinet or directly to critical equipment. A multi-phase SPD and noise filter, the VAL-SQ SP Series protects sensitive equipment even in the worst environmental conditions. It can be installed adjacent to sub-panels or directly to sensitive equipment. It provides 80,000A or 120,000A of surge current rating per phase. The VAL-SQ SE Series provides maximum surge protection for the service entrance and remote locations in industrial, medical and commercial applications. Available with 120,000A, 160,000A and 200,000A surge current ratings, it can be mounted near the circuit breaker, reducing connecting leads and improving performance. In addition to surge protection, the VALVETRAB-SQ line includes status LEDs, audible alarms, sine wave tracking filtration and function monitoring. All of the SPDs comply with UL 1449 2nd Edition, 2007 requirements.
