The EKM1-63 MCB is our classic L7-structure 6kA circuit breaker. Having been on the market for over 15 years, this product is a star performer for our company, with cumulative sales exceeding 100 million poles. It maintains a failure rate of approximately 50 PPM and has received consistent positive feedback from customers.
As one of China's top three manufacturers of L7-structure MCBs, ETEK has leveraged this proven platform to develop a range of derivative products. These include the DPN (EKM1-40N), high DC capacity breakers (EKM1-125H, EKM3-125H), and RCBOs (EKL3-63, EKL5-63, EKL2-40).
