Description

The MTL MA4000 surge protectors prevent surges and transient overvoltages conducted through power circuits from damaging electronic systems such as control panels, distributed I/O, motor and pump controls and many other remotely mounted pieces of equipment. The surge protectors are available in a range of voltage options (24 VDC, 48 VDC, 110 VAC and 230 VAC) making them universally suitable for protecting power supplies in hostile environments.

Fully automatic in operation, MA4000 devices react immediately, clamping voltage surges without causing undue leakage losses under normal conditions. MA4000 devices reset automatically and are maintenance-free with no operator intervention required. The MA4000 is designed to protect and survive the level of transient associated with the industrial environment, extending the life of equipment that 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 standard and can be used to indicate the status of an MA4000 unit. The wires have a normally closed contact that 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 2014/34/EU for mounting into Zone 2, Category 3G hazardous areas, which is especially useful for protecting the next generation of hazardous area mounted control systems. The MA4000's aluminum case is silica-filled, a requirement of Ex q certification.
