Schaltbau C310 1 Pole AC & Bi-Directional DC NO Contactors
Schaltbau C310 1 Pole AC and Bi-Directional DC NO Contactors are compact switching devices designed for high-power AC and DC applications. The C310 series supports rated insulation voltages up to 1500V and combines high making, carrying, and short-time withstand capabilities in a space-saving package. C310 contactors are available in versions rated for 150A, 300A, and 500A applications. The bidirectional DC switching capability allows the C310 series to reliably switch and disconnect current in either direction. This functionality is beneficial in systems that experience charging and discharging cycles. Schaltbau C310 contactors feature high contact forces, optimized silver contacts, and integrated electronic coil control, helping ensure reliable switching performance while reducing holding power requirements. Built for demanding power-management applications, the C310 series supports battery storage systems, inverter DC circuits, combiner boxes, and electric-mobility power architectures.
