The MC1A miniature contactor is a size-optimized 3-pole contactor with an integrated auxiliary contact, AC control and screw connections. It offers the optimal solution when high performance is required but space is limited. These miniature contactors can be used in residential buildings, commercial buildings and many industrial applications to control single or three-phase loads up to 4 kW (AC-3) and 20 A (AC-1) at 690 V or to switch control signals. In addition, up to 6 additional auxiliary contacts can be mounted on the front or side. The contactor is suitable for DIN rail or wall mounting.
