CQMGU Series Distribution Box
The CQMGU Series Distribution Box is a CHAC distribution box for organized circuit distribution and termination. The page keeps the model-specific technical table and original product images so buyers can verify voltage, current, configuration, mounting and applicable standards before ordering. Final suitability depends on the complete circuit, installation method and destination-market rules.
Product Overview
CQMGU Series Distribution Box is a distribution box intended for organized circuit distribution and termination. The current product record identifies it for residential, commercial and light-industrial panels. Use the exact model variant and preserved technical source as the basis for procurement rather than assuming that every family member has the same rating.

Key Features
Typical Applications
Typical use can include residential, commercial and light-industrial panels when the project confirms system voltage, current, fault or surge exposure, conductor and enclosure requirements, and the selected variant’s installation instructions. This page does not replace the project design or the authority having jurisdiction.
Applications and Selection Guide
Use the following decision points with the preserved model data. Product-family descriptions explain intent, but the exact technical table controls the ordered variant.

CQMGU Product FAQ
What is the CQMGU distribution box for?
It organizes and protects outgoing circuits in the application context shown by the product record. Confirm capacity, mounting and enclosure requirements.
How do I choose the box size?
Count modules or circuits, allow wiring and heat-dissipation space, and check the exact dimensions, cover and mounting method for the selected model.
Surface or flush mounting?
Use the mounting option published for the series and verify wall depth, fixing points and maintenance access.
Can it combine power and data?
Some distribution-box variants include dedicated power and weak-current or data arrangements. Confirm the exact model layout before ordering.
What protection rating applies?
Use the rating stated for the exact enclosure and installation condition. Knockout removal, cover fit and cable entries can change the effective protection.
What should be included in an order?
Provide model, size or module count, mounting type, color, quantity, destination market and required drawings or packaging details.
Confirm the Right CQMGU Configuration
