With the C310 series, the company offers a reliable alternative to gas-filled devices, which have been commonly used up to now. The first types in the new series are designed for permanent currents of 150 A, 300 A and 500 A. Schaltbau offers an innovative solution, based on their experience and expertise in developing electromechanical switchgear and controlling DC arcs. The modular concept allows one arc chamber to be used for 60 V, 1,000 V or 1,500 V on the same basic unit. These chambers work on a permanent-magnetic basis, ensuring compact dimensions and a low weight. The arc chambers can be removed without tools, to allow inspection of the contact system. As the coil current is regulated, these devices always work equally reliably regardless of the ambient temperature. In addition, this means that the monostable type has low energy consumption in the switched-on state. The bistable version is designed to have zero power draw in both end positions. Contactors in the C310 series have a high making and breaking capacity as well as a high short-term current rating.
The new DC contactors are highly resilient to shock and vibration stresses, and meet the stringent requirements of ISO 12405 (automotive). Since both current directions are reliably controlled, the contactors are ideal for all applications with energy recovery. A typical example of this would be energy storage systems, where batteries are charged and then discharged again. Other application fields for the C310 series are regenerative systems, battery-powered vehicles, DC charging stations and photovoltaic installations.
