Scaling Power Safely: Parallel and Series Connection of Contactors
The electrical and mechanical behavior of contactors in parallel and series configurations
As power levels in DC applications continue to rise while the space constraints remains tight, engineers are increasingly looking for new solutions for reliable DC contactors: either new products or smart ways to connect existing products in parallel to increase current capacity, or in series to improve breaking performance.
In this webinar, we explore the electrical and mechanical behavior of contactors in parallel and series configurations. You will gain practical insights into current sharing, voltage distribution, thermal performance, and real-world breaking behavior.
Key Highlights
Highlights include:
- How current divides between parallel contactors – and what it means in practice
- Why parallel connection improves thermal performance but not breaking capacity
- How series connection increases voltage breaking capability
- Practical design considerations and real test results
Key take-aways
- How to handle higher thermal current with a parallel connection of contactors
- How to achieve better breaking performance with a series connection of contactors
- Practical examples from real-life test results
