Schaltbau, a provider of a wide range of DC power solutions, has expanded its Eddicy lineup with a series of compact, high-performance contactors designed to meet the requirements of stationary and mobile megawatt charging.

“Megawatt charging represents a milestone in commercial e-mobility. By reducing charging time to the length of a driver’s break, it significantly maximizes both flexibility and efficiency off green transportation,” said Helmut Pusch, CEO of Schaltbau Group.

The new C305 and C805 contactors support the current Megawatt Charging Standard (MCS) level 2 of 1,500 A, and the C330 and C830 contactors are 3,000 A bidirectional contactors designed to enable MCS level 3 high-power DC charging. All four products feature a compact, open-isolation concept designed to prevent rupture even under the heaviest failure conditions and heavy short-circuit currents, preventing damage to surrounding components. The contactors can withstand a current of up to 15,000 A for five milliseconds without the contacts welding. The series features separate contact systems for switching and current carrying.

Silver alloy contact pills deliver a contact resistance as low as 35 µOhm. An integrated economizer ensures optimal pull-in performance during switch-on and minimizes energy consumption in holding mode. According to the company, the new contactor series reduces power losses in the system, delivering up to 25% of energy cost savings.

“Power losses grow quadratically with current, so minimizing contact resistance in high-current applications is crucial for maintaining an efficient energy transfer,” explains Pusch. “That’s why our new Eddicy contactors are ideal for high-current applications like fast charging, as well as other energy and e-mobility applications such as battery storage systems and test benches.”
