MA4000 range

Although designed specifically with bussed systems in mind, the MA4000 range is available in a range of voltage options (24Vdc,48Vdc,110Vac and 230Vac) making it universally suitable for protecting power supplies in hostile environments. These 20kA rated, single phase devices provide protection for AC or DC power supplies with no restriction to the amount of load current. Connected in parallel via flying leads, MA4000 devices are easily connected to the power supply. The robust IP53 (NEMA 13) rated enclosure is simply ‘wall mounted’ via the four fixing points provided. Self-certified to ATEX 2014/34/EU for mounting into Zone 2, Category 3G hazardous areas, the MA4000 is especially useful for protecting the next generation of Hazardous Area mounted control systems.
