CTB2PH Static Switching Module
The static system is the most convenient in case of large and fast fluctuations of the load current (load changes lasting a few milliseconds to several seconds). The advantages of the static system are the connection at zero crossing voltage and the disconnection at zero current crossing, thus avoiding inrush current transients. CTB2PH modules are composed of two basic parts: control module and power block. As an added accessory, both parts can be mounted with a polycarbonate cover.
