Product Profile

The EKM1-125H MCB, developed on our robust L7 Structure, is designed for high-end and demanding industrial protection. With current ratings from 63A to 125A and superior breaking capacities of 10kA, or up to 15kA, it delivers reliable circuit protection for critical applications.

People ask:different between 6kA,10kA,15A breaking capacity?

6kA: Suitable for applications with lower prospective short-circuit currents, typically at the sub-distribution level or in residential/commercial settings with current-limiting devices upstream.
10kA: A standard rating for general industrial and commercial distribution boards, offering robust protection for a wide range of applications.
15kA: Provides enhanced protection for demanding industrial environments, main distribution boards, or locations closer to the power source where the risk of high fault currents is greater
