- Hartmann & Braun Contronic plug-in module
- Identification records associate MA12 with 07761213D and 0776123C
- Exact suffix compatibility must be verified against the installed module and cabinet documentation
ABB MA12 is a Hartmann & Braun Contronic plug-in module designed for documented industrial control installations.
The 07761213D and 0776123C references support product identification but do not establish that differently marked MA12 modules are electrically or functionally interchangeable.
Before replacement, verify the complete MA12 identity, suffix, connector keying, rack position, board population, and applicable cabinet drawings.
Availability, condition, price, and shipping time for ABB MA12 are confirmed during quotation.
