The MTL MA4000 surge protectors are available in a range of voltage options (24Vdc, 48Vdc, 110Vac and 230Vac) making them 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.

Fully automatic in operation, MA4000 devices react immediately, clamping voltage surges without causing undue leakage losses under normal conditions. No operator intervention is required, MA4000 devices reset automatically and are maintenance free. The MA4000 is designed to protect and survive the level of transient associated with the industrial environment, extending the life of equipment which could otherwise be stressed or damaged if not properly protected.

Connected in parallel via flying leads, MA4000 devices are easily connected to the power supply. The robust, IP54 (NEMA 13) rated enclosure is simply ‘wall mounted' via the four fixing points provided.

Remote monitoring is provided, as standard, which can be utilized to provide indication of the status of an MA4000 unit. These wires have a normally closed contact which will open to indicate that reduced protection is present. However, continuity of protection is ensured via the redundancy capability of the MA4000 range. Additionally, thermal fusing, incorporated into each MA4000 unit, ensures a high level of safety.

The MTL MA4000 Series is self-certified to ATEX 94/9/EC for mounting into Zone 2, Category 3G hazardous areas, especially useful for protecting the next generation of Hazardous Area mounted control systems. Also, the MA4000's aluminium case is silica filled, a requirement of Ex q certification. The MA4000 also has a 10 year product warranty.
