MC1I, MC1K, MC2I, MC2K 3- pole mini contactors with screw terminals

4 to 5.5 kW
DC operated - low consumption

MC..I and MC..K 3-pole mini contactors are a high performance but space saving solution for the
control of small motors and resistive loads up to 690 V AC and 220 V DC.
These contactors are designed with 3 main poles and one built-in auxiliary contact:
2CDC211007V0019 • control circuit: DC operated
• coil with very low energy consumption; suitable for direct control by PLC outputs
• only for K variants: add-on auxiliary contact blocks for front or side mounting (up to 2 additional
contacts)
