The APEX Imax Series of surge protection devices is a Ul type 2 SPD designed to protect a wide range of 120VAC power configurations. The standard surge protector enclosure is a fiberglass composite, UL Type 4, with metal enclosure options depending on user requirements. The design is based around a modular approach using robust surge assemblies that each bolt directly across AC bus bars. Each surge element connects to the monitoring board through a card edge connector system and its functional health can be discriminated through the visual and relay alarm connection point features. All visual indication is shown through the front panel window, and the annunciation contacts are located conveniently on the interior main board assembly and multiplexed for easy failure demonstration.

The surge elements are constructed inside 94V0 flame rated plastic housings. The APEX Imax utilizes an extraordinarily robust combination of silicon avalanche suppressor diode (SASD) and metal oxide varistor (MOV) technologies to achieve a balance of very low voltage protection levels at high induced surge currents, with effective abnormal over-voltage fault current fail safe mode. The surge elements are constructed using Transtector’s ASAT[tm] patented assembly construction to achieve this premier performance. The surge protector is constructed in such a manner as to effectively couple the surge performance of high endurance SASD and MOV elements along with safe, built in disconnect elements. The Apex Imax Series are listed to UL 1449 and are Motorola R56 compliant.
