MK vs MKC Series – What’s the Difference?

While both the MK and MKC series share the same core characteristics—such as aluminium housing, IP55 protection, permanent capacitor operation, and insulation class F—the MKC series offers enhanced installation flexibility thanks to its removable feet and side-reversible terminal box. This makes the MKC motors especially suitable for compact or custom-mounted configurations where space orientation matters.

Additionally, the MKC range includes frame sizes starting from IEC 56 and is manufactured and kept in stock not only in 2- and 4-pole versions—as is typical for single-phase motors—but also in 6-pole variants. By contrast, the MK series starts at IEC 71, features a natural unpainted aluminium finish, and is specially designed with higher starting torque, making it a more suitable choice for complex applications with increased torque demands.
