B&R HCMARC-0CT — MAC/MARC Housing Module
The B&R HCMARC-0CT is a housing / mechanical module
from B&R’s industrial automation range, designated by the HCM… prefix (housing module). B&R uses the HC prefix for
mechanical and housing assemblies that carry the electronic modules of a control system —
for example, the related module HCMARC-0 (MARC housing) and other HCM… variants exist in B&R’s listings. The CT suffix denotes
a specific configuration/variant of the housing. Manufactured by B&R (Bernecker &
Rainer), Austria. Typically used as a maintenance and retrofit spare.

HCM…housing / mechanical module- Related to B&R’s MARC-family modules
-0CTdenotes a specific variant- Part of B&R’s modular automation hardware
- Maintenance / retrofit spare
Key Features & Functions
Housing / Carrier Module
Provides the mechanical housing and mounting for the associated MARC-family module assembly, holding the electronics within the system.
Modular Assembly
Part of B&R’s modular hardware approach, allowing the housed module to be installed, maintained or replaced within the wider system.
Variant Configuration
The -0CT suffix indicates a particular configuration of the HCMARC housing; confirm against the official datasheet.
Industrial Construction
Built for continuous operation inside industrial control cabinets and process environments.
Technical Specifications
| Designation | HCMARC-0CT |
|---|---|
| Brand | B&R (Bernecker & Rainer) |
| Module Type | Housing / mechanical module |
| Series | HCM… (housing module) — related to MARC family |

Source note: A matching listing for HCMARC-0CT was found associated with
B&R, and the related HCMARC-0 (MARC housing) exists in B&R’s range.
However, exact dimensions, material, mounting type, environmental ratings and system
compatibility for the HCMARC-0CT specifically were not confirmed from an
official B&R datasheet — verify these before purchase.
Typical Application Scenarios
- Control Cabinet Mounting: housing the associated MARC-family module within a control system.
- Machine & Plant Control: serving as mechanical hardware in industrial automation installations.
- Legacy System Maintenance: keeping existing B&R installations running with genuine spare parts.
- Retrofit & Repair: replacing damaged or ageing housing modules in established systems.
- Spare Part Replacement: servicing module housings in the field.
Frequently Asked Questions
What is the B&R HCMARC-0CT?
It is a B&R housing / mechanical module (designated by the HCM… prefix)
associated with the MARC-family modules, in the -0CT variant configuration.
What does the part number mean?
HC indicates a housing/mechanical module, MARC identifies the
associated module family, and -0CT denotes the specific variant. Confirm the
exact meaning in the official B&R datasheet.
How does it differ from HCMARC-0?
HCMARC-0 is the base MARC housing designation; the -0CT suffix indicates a
specific configuration/variant. Confirm the exact differences before substitution.
Which systems is it compatible with?
It is associated with B&R’s MARC-family modules. Confirm the exact system and configuration against official documentation.
Where can I find the official datasheet?
Official technical documentation is available from B&R Industrial Automation and authorized distributors. Verify all specifications there before purchase.
