The factory-made control modules of the USC710D4-HA series are designed to control changeover and monitoring modules with load switches or circuit breakers. Load switches and circuit breakers are used as switching elements. In conjunction with the TMX-HA operator panel, also manual control of the changeover module is possible, e.g. for servicing purposes. Information exchange between the changeover modules and the alarm and operator units is established via bus technology. The module is suitable for mounting onto all common DIN rail systems (equipment racks have to be provided).

• Complete solution for changeover modules with integrated load switch or circuit breaker (3-pole or 4-pole) of different manufacturers
• Bus technology for easy installation and reduced fire load
• Clear menu structure with LC display allows easy parameter setting
• Internal functional testing including checking the operating times
• Variable changeover period t < 0.3…20 s + operating time of the switching element
