C303-350-G0P-24I-V1 (Ecosave-C)
The Schaltbau C303 series bidirectional DC and AC contactors are engineered for operating voltages up to 1,500 volts and can continuously conduct currents up to 500 amps. Thanks to magnetic actuators with three coil control options, these contactors offer high flexibility for use in modern industrial settings, even at ambient temperatures up to +85°C. They feature a short-circuit switching capacity of up to 2,000 amps and a space-saving design, making them ideal for applications that demand high inrush currents or large power capacities where installation space is limited.
In short-circuit conditions, the contactors can endure currents of up to 5,000 amps for 20 milliseconds without contact welding, ensuring full operational capability. This enables reliable disconnection of high-power loads regardless of current direction. Such true bidirectional functionality is essential for systems with energy recovery, including charging and discharging processes found in charging infrastructure and energy storage systems (ESS). Additional applications include DC circuits in inverters, photovoltaic combiner boxes, battery management systems (BMS) for emission-free drive technologies, and stationary solutions for grid stabilization.
Features and Benefits:
-
Available with three coil controls:
-
Ecosave: With energy-saving PWM module for optimum power consumption when switching and low heating when holding
-
High efficiency drive (HED): With economical drive without PWM module for maximum efficiency
-
Precharging contactor or for external PWM control: For limiting high making currents and to protect main contactors, special variant without economy circuit
-
Up to 25% reduction in energy costs for economical continuous operation due to an extremely low contact resistance of 100 microohms (typical)
-
Safe arc extinguishing – no risk of explosion
-
As a compact air contactor with permanent magnet arc extinguishing without gas encapsulation, the C303 compensates for overpressure
-
V2G-ready for bidirectional charging stations, which enable electric vehicles not only to charge, but also to feed electricity into the grid or use it for the domestic power supply
-
Optimal integration and performance thanks to magnetic drives in three different versions
-
