Leviton offers two new panel-mounted surge protective devices (SPDs) for industrial and commercial applications, the 37120-007 and 37277-007, designed for facilities with 3-phase WYE-configured systems where surge protection for all seven modes in the AC distribution network is required. The units are ideal for service entrance, distribution and branch panel applications in schools, commercial offices and institutional environments.

The panel mount devices provide dedicated protection against high-energy transient voltage surges. Their parallel-operated design features 40 mm-diameter, metal-oxide varistors and EMI/RFI filter circuitry with high-voltage-rise capacitors for harmonic tolerance. The units can be flush- or surface-mounted and are available with brackets that permit any type of installation including flat or side mounting to studs. An easy -view window on the cover enables users to conveniently verify the status of all modes. Both models are 200KAIC rated to comply with new NEC article 285 requirements.

The units also feature low clamping and high surge current performance, real-time diagnostics that monitor power and suppression status for each phase and LED indicators as well as an audible alarm. They are rated 100kA per mode. Both models meet ANSI/IEE C62.41 and C62.45 standards for Category A, B and C environments and are UL 1449 (2 nd Edition) Listed. They are backed by Leviton's 10-Year Warranty.
