Providing enhanced energy efficiency, flexible power flow control, and extended battery lifespan in various industries, bidirectional contactors facilitate energy recovery in electric vehicles(EVs), improving the economic viability of e-mobility. But what features are key for reliable performance?
Unlike unidirectional contactors, bidirectional contactors offer engineers a two-way path, optimizing energy use and enhancing system resilience with remarkable flexibility. They must excel at controlling electrical power flow in both directions, enabling dynamic power management for applications like bidirectional charging and grid interconnection.
Key Operating (KO) criteria are crucial in bidirectional contactor design, ensuring top performance, reliability, and safety in varied conditions. That’s why it’s important to consider parameters such as contact resistance, switching speed, voltage, current ratings, and environmental durability. Adhering to these criteria ensures consistent, reliable operation, even in tough industrial environments, safeguarding system integrity and longevity.
Low contact resistance, for example, reduces power losses and heat dissipation. Through advanced material selection, precision engineering, and innovative designs, contact resistance is minimized, optimizing energy efficiency and system performance. This reduction not only improves power transmission efficiency but also extends the contactor’s lifespan, reducing maintenance needs over time.
With Eddicy — Schaltbau‘s brand for energy and e-mobility — the company offers the C303 contactor that meets these strict technical criteria with the following features:
- Unmatched short-circuit resilience: The ICM handles 15kA/5ms, double that of most competitors, ensuring robust performance and reducing risks during short circuits.
- Enhanced safety: this contactor series is non-gas encapsulated, extending lifespan and safety by eliminating explosion risks and ensuring controlled responses to danger.
- Impressive overload capability: The bidirectional contactor handles 8,000 A for 20 milliseconds without causing fires, with non-welding contacts ensuring timely fuse triggering for added safety.
- Low resistance and temperature rise: With low contact resistance, it surpasses competitors like WB, generating less heat during installation for energy-efficient operation and environmental sustainability.
- Provides full plug-and-play capability — simplifying installation, integration, and maintenance processes.
Bidirectional contactors are crucial for global sustainability, enhancing energy efficiency, grid integration, and renewable energy use. They help us reduce greenhouse gas emissions, foster energy independence, and empower society to engage in the energy transition on every level.
