MCRC 4-pole mini contactor relays with screw terminals

DC operated

MCRC 4-pole mini contactor relays are a high performance but space saving solution used for con-
trol functions or for switching small loads up to 6 A.
2CDC211023V0019 These contactors are designed with 4 poles with various contact combinations:
• 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
• suitable for rail or wall mounting. 04

Note : Other contact configuration available. Please consult your ABB local sales organization.
* 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.
