1. Product Overview

The GLBG300104P0002 designation identifies an ABB cable
release accessory. Its documented product description
is “CABLE RELEASE 550 MM.” The length is a key
identification detail and should remain associated
with the complete part number throughout procurement,
technical review, and maintenance documentation.

In industrial switchgear, accessories can form part of
a larger mechanical or operational assembly. Selecting
the correct accessory requires more than matching a
general product description. The part number, specified
dimensions, equipment family, and intended installation
should be reviewed together to avoid confusing similar
components.

ABB’s low-voltage switchgear service documentation lists
this model alongside other cable release components.
The same listing includes variants with different
specified lengths. This confirms that length is an
important distinction within this group of parts.
Detailed operating functions and installation
instructions should be taken from the documentation
applicable to the specific switchgear assembly.

2. Product Identification and Specifications

The following table summarizes the product information
supported by the ABB documentation listing. Information
not established by that listing is intentionally left
unspecified rather than inferred from the model code.

The table records the available identification details
without assigning unsupported material specifications,
connection dimensions, operating forces, or mechanical
ratings. These parameters should be confirmed using
the applicable technical drawing or parts list before
the component is selected for a particular installation.

3. Role of Cable Release Accessories

A cable release is a mechanical accessory whose precise
function depends on the equipment design in which it
is installed. Cable-operated mechanisms can transmit
movement between an operating point and a mechanism
located elsewhere in an assembly. The design of the
associated equipment determines how the cable is routed,
supported, adjusted, and connected.

For the GLBG300104P0002, the published product
description establishes the component category but
does not, by itself, provide a complete functional
diagram. Its exact actuation purpose, attachment
points, and relationship to other switchgear
components should therefore be confirmed from the
corresponding ABB assembly drawing or service
instructions.

Understanding the role of an accessory within the
complete assembly helps prevent incorrect installation.
A component that appears mechanically similar may have
a different length or interface and may not follow
the same routing path. Reference to the original
equipment configuration is especially important when
a part is identified from a maintenance list rather
than from a detailed drawing.

4. Importance of the 550 mm Length

The 550 mm designation is part of the documented
description for GLBG300104P0002. It should be treated
as a defining identification parameter rather than
as an optional descriptive detail. Cable-operated
assemblies depend on suitable routing and geometry,
so the specified length can affect whether a component
fits the intended arrangement.

ABB’s documentation lists other cable release
designations with lengths of 600 mm and 1000 mm.
These related variants demonstrate why the complete
part number should be checked before ordering or
installing a replacement. A difference in length
should not be dismissed merely because two items share
the same general product description.

The listed length should not be used as a substitute
for a dimensional drawing. Where exact installation
dimensions, cable travel, connection geometry, or
adjustment requirements matter, the applicable
engineering documentation remains the reference for
confirming the component’s suitability.

5. Application in Low-Voltage Switchgear

ABB MNS 3.0 is a low-voltage switchgear platform
supported by product and service documentation
covering assemblies, accessories, and replacement
components. Within such equipment, correct component
identification helps maintain consistency between
the installed assembly and its technical records.

Switchgear maintenance may involve reviewing component
identifiers, checking mechanical interfaces, examining
the equipment arrangement, and comparing the installed
parts with the applicable bill of materials. The
GLBG300104P0002 designation can be used as a reference
when locating the corresponding cable release in
equipment documentation.

However, the presence of a part number in MNS 3.0
service documentation does not establish universal
compatibility with every MNS assembly or configuration.
The switchgear type, functional unit, production
configuration, and applicable drawing should be checked
before the part is assigned to a specific application.

6. Identification Before Replacement

Before identifying GLBG300104P0002 as a replacement
component, compare the complete designation with the
original part label or the equipment parts list.
Confirm that the documented description is Cable
Release and that the specified length is 550 mm.
This initial comparison reduces the risk of selecting
a related but dimensionally different variant.

The equipment model and the relevant assembly reference
should also be recorded. If the original part is
difficult to identify, compare its installation
location and physical arrangement with the applicable
technical drawing. Photographs may help document
the original routing and attachment points, but
should not replace dimensional verification where
precise fit is required.

If the model number, physical configuration, or
equipment documentation does not agree, pause the
selection process until the discrepancy is resolved.
A similar-looking component should not be assumed
interchangeable solely because it belongs to the
same general accessory category.

7. Installation and Maintenance Considerations

Installation should follow the instructions and
drawings applicable to the specific switchgear
assembly. The cable path, mounting points, attachment
method, and required mechanical movement should be
checked against the intended configuration. Avoid
introducing bends, interference, or routing changes
that are not permitted by the equipment design.

Before work begins, personnel should follow the
site’s electrical safety procedures and the
manufacturer’s requirements for isolating and
securing the equipment. Any functional checks should
be performed only under the conditions specified
by the relevant service instructions and by qualified
personnel.

Maintenance records should capture the installed
part number and the equipment assembly in which it
is used. Recording the specified length and the
source of the identification information helps
technicians distinguish the 550 mm version from
related cable release variants during future work.

8. Documentation and Spare Parts Management

Consistent part-number management supports technical
traceability in industrial facilities. When a
component is entered into a spare parts database,
the manufacturer, complete model designation,
published description, and documented dimensions
should be retained as separate data fields where
possible.

For GLBG300104P0002, the description should preserve
both the cable release category and the 550 mm length.
The part should not be grouped indiscriminately with
the 600 mm or 1000 mm variants. Clear differentiation
improves inventory accuracy and makes it easier to
compare a requested component against the original
switchgear documentation.

If further technical details are needed, the next
reference should be the relevant ABB parts catalogue,
assembly drawing, or service documentation. These
sources can establish the precise installation
relationship and any configuration restrictions
that cannot be determined from the product description
alone.

9. Product Summary

ABB GLBG300104P0002 is documented as a Cable Release
with a specified length of 550 mm. It appears in
ABB low-voltage switchgear service documentation
associated with the MNS 3.0 documentation context.
The exact part number and length are the primary
confirmed identification details available for
this component.

For technical selection, installation, or replacement,
verify the original part designation and consult the
applicable assembly documentation. Confirming the
equipment configuration and mechanical requirements
is essential because related cable release variants
are listed with different lengths.
