DC Contactor – C310 series
£0.00
Product Description
The C310 is a bidirectional DC contactor from Schaltbau. The C310 switches high power ranges within a small footprint. Its making capacity of up to 2,500 A is necessary for discharging intermediate circuits through a resistor.
In the C310A/500 design, the contactor can continuously conduct up to 500 A. In the event of a short circuit, 3,000 A can even flow for one second without the contacts fusing. The contactor therefore maintains its full function in order to disconnect high power ranges if necessary – irrespective of the current direction.
This full bidirectionality is important for systems with a charging and discharging process, such as in battery networks or electric vehicles. Other typical application areas are the DC circuit in inverters, combiner boxes in photovoltaic systems or the management of battery storage systems.
