Meter-Treater's MST Modular Surge Protector

The patent pending MST Series is a modular, parallel installed, SPD (surge protection device) designed for commercial, industrial and residential applications. Models are available for all standard electrical services and provide either 50kA or 100kA of surge energy handling per phase. This rating is 10 times the energy handling of the IEEE's highest Category C location rating of 10kA/20kV using an 8x20µs waveform. All models carry a 100kA rms symmetrical fault current rating making expensive disconnects and costly replacement fuses unnecessary.

MST units incorporate a replaceable MT protection module that is completely self-contained with fusing and diagnostic circuitry. The MT module can be replaced in the field, thereby eliminating the need to remove the entire unit from service. Replacement modules include the entire operating unit including all phases, all modes, the fuses and even the diagnostics. Replacement Modules available for the MST Series devices.
