XTE/XHP SERIES
XTE/(x)XHP/(zz)
X = VOLTAGE CODE
ZZ = OPTIONS

The XTE/XHP Series is a modular parallel suppressor designed for service entrance or downstream panelboard applications. The XTE/XHP is a multi-stage suppression circuit consisting of field proven, fast acting 40mm MOVs. A redundant surge suppression path is provided for each mode (L-N or L-L, L-G, N-G) guaranteeing continuous service. Each surge suppression module is individually fused and utilizes APT’s Patent Pending TranSafe ™ circuitry with thermal cutout to ensure safe operation during severe over-voltages and high fault current conditions. The suppression elements are encapsulated in UL Listed and Patented Ceramgard ® providing another level of safety. A filter network is added to provide wave shape smoothing and a high level of EMI/RFI noise attenuation. 

On-line diagnostics continuously monitor the unit status and feature redundant LEDs to signal a reduction in surge capacity or loss of a suppression circuit. An audible alarm with test and silence features is included in the standard diagnostic package. All APT products are designed and tested in accordance with the recommendations and procedures of ANSI/IEEE C62.41 and C62.45. The XTE/XHP is UL 1449 Second Edition Listed, and qualified for service entrance applications under Section 37.3 for their most severe, 25kA, fault current test.
