The MC-12a/4 is a compact 4-pole AC magnetic contactor rated up to 12 A (AC-3, 400 V), suitable for switching resistive and inductive loads in both motor and general-purpose control circuits. It maintains the same reliable Metasol architecture, offering consistent durability and modular compatibility.
The Polar Energy Assessment:
Engineers choose the MC-12a/4 when a 4P configuration is required without stepping up to a larger frame size. It’s particularly valued for its versatile contact arrangement (4P main or 3P+1A) and coil voltage flexibility. Functionally, it bridges the gap between small 3-pole contactors and heavier-duty modular assemblies.
