MC2C 3-pole mini contactors with screw terminals

5.5 kW
DC operated

MC2C 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.
2CDC211006V0019 These contactors are designed with 3 main poles and one built-in auxiliary contact:
• control circuit: DC operated
• add-on auxiliary contact blocks for front or side mounting (up to 6 additional contacts) and
a wide range of accessories
MC2C310AT • suitable for rail or wall mounting. 04

* With the extended operating limits coils:
- at nominal voltage, Uc, a higher number of additional auxiliary contacts can be attached to the device
- a wider range of voltages, -30% ≤ Uc ≤ +30%, can be used for the operation with a limitation of the number of auxiliary contacts.
