Schaltbau C300 1 Pole Bi-Directional DC NO Contactors
Schaltbau C300 1 Pole Bi-Directional DC NO Contactors are compact, normally open contactors designed for high-power DC switching applications. The series supports bi-directional current flow and offers rated insulation voltages up to 1500V, making it suitable for energy storage, power conversion, and high-voltage DC distribution systems. C300 contactors support continuous currents up to 500A and provide high short-time withstand current capabilities. An integrated electronic coil controller with PWM regulation helps optimize holding power, reduce energy consumption, and support reliable switching performance across varying operating conditions. Schaltbau C300 1 Pole Bi-Directional DC NO Contactors are designed for applications that require reliable disconnection and switching of high DC power regardless of current direction.
