Panel-Mounted 7-Mode 37000 Series Surge Protective Devices (SPD's)

Panel-Mounted 7-Mode 37000 Series Surge Protective Devices (SPD's)

Cat. Nos. 37120-007 and 37277-007 are designed for indoor installation at the service entrance, distribution and branch panel locations for protection against high-energy, transient voltage surges. These devices provide dedicated surge protection for each phase to neutral, phase to ground and neutral to ground in three-phase WYE AC applications through parallel wiring that facilitates connection to any service ampacity.

Standard Specification:

All 37000 Series units are designed for use where a multi-phase, transient voltage surge suppressor (TVSS is specified). They provide full, 7-mode protection in 120/208V and 277/480V WYE-configured, 3-phase systems. Their parallel-operated design features 40mm-diameter, metal-oxide varistors and EMI/RFI filter circuitry equipped with high-voltage-rise capacitors for harmonic tolerance. Both units have been tested to ANSI/IEEE C62.41 and C62.45 standards for Category A, B, and C environments and are UL 1449 (2nd Edition) Listed. They are also backed by Leviton's 10-Year Warranty.

Features

  • 7-mode protection (each phase to neutral, each phase to ground and neutral to ground) for WYE-configured, 3-phase AC systems
  • Low clamping and high surge current performance; Clamping envelope tracks contour of the AC sine wave
  • Real-time diagnostics monitor power and suppression status for each phase and provide both LED indicators and an audible alarm
  • Equipped with dry contacts for remote diagnostics
  • Rated 100kA per mode based on actual tests
  • 1000-cycle, 10kA Category C3 tested
