Sep 22, 2003 #1 flyboyz Electrical Sep 22, 2003 7 0 0 CA Hi, I'm sourcing for a current unbalance relay for capacitor bank protection. It's a 3-phase relay and input 5A. It has to be single function relay and inexpensive. If you guys have any recommendation on manufacturers, pls let me know. Thanks a lot. TK
