Phoenix Contact VALVETRAB MS surge protection devices
Switching operations are by far the most common cause of overvoltages. Surge protective devices according to AS/NZS 1768 Cat. C3 provide effective protection against these dynamic disturbance variables. Whether an industrial or residential environment, Cat. C3 SPD protection is designed to ensure point of entry protection for installations and devices.
Features include: low voltage protection level with varistor-based protective circuit; powerful disconnect device provides optimum protection; high surge capacity of Max Single Impulse of 100 kA (Imax 8/20 uS); usage up to 250 A without backup fuse saving time, money and space; and universally pluggable protective devices enable ease of maintenance.
Phoenix Contact VALVETRAB MS devices are surge protective devices with a modular design consisting of a base element and a protective plug. The overall width per path is 17.5 mm, corresponding to one unit of horizontal pitch (HP).
Ready-to-install VAL-MS SPDs are available in all configurations for an application (three-phase and single-phase, MEN and separate N-E options). Bi-connect terminal blocks enable easy bridging for residual-current devices and fuses while impedance-neutral plug insertion and removal facilitates insulation resistance testing. There is no need for complicated wire disconnection and reconnection. Standard relay alarm outputs allow easy connection to remote monitoring systems and coded plugs make replacement simple and error-free.
