CAEN-5X2-MLO-120/2P

Product Overview

The Crestron CAEN-5X2-MLO-120/2P is a main-lug-only automation enclosure designed to house Crestron CLX and CLXI lighting control modules in residential and light commercial installations. Configured as 5 rows by 2 columns of module slots with 20 breaker positions, it provides branch circuit protection for a substantial lighting control deployment within a single, self-contained enclosure rated for 120V split-phase North American electrical systems.

Product Description

Crestron Automation Enclosures (CAEN) serve as the central wiring point and module housing for Crestron’s CLX-series dimmer and relay modules. The CAEN-5X2-MLO-120/2P mounts in a standard electrical panel location and contains all branch circuit wiring within its enclosure, keeping installations clean and code-compliant.

The MLO (main lug only) configuration means the enclosure does not include a main breaker of its own. Protection for the enclosure is provided by the building’s upstream electrical panel, which is standard practice for sub-panel and dedicated-circuit lighting control installations. This design simplifies the enclosure footprint and reduces component count where the upstream protection is already in place.

With 5 module rows and 2 module columns, the enclosure accommodates a mix of Crestron CLX dimmer and relay modules sized according to the project’s load count. The 20 breaker slots support branch circuit protection for the connected loads. Split-phase 120V operation aligns with standard North American residential and light commercial electrical infrastructure.

For electricians and AV integrators working on Crestron lighting control projects, the CAEN-5X2-MLO-120/2P provides a defined, purpose-built housing that keeps the lighting control system organized, serviceable, and clearly separated from the general electrical panel.

• Retrofit installations where a dedicated lighting control enclosure is added alongside an existing electrical panel

Technical Specifications

Frequently Asked Questions

What does MLO (main lug only) mean?

MLO means the enclosure does not include its own main breaker. The upstream electrical panel supplying the CAEN-5X2-MLO-120/2P provides the main overcurrent protection. This is a standard configuration for sub-panel and dedicated circuit applications in residential and light commercial electrical work.

Which Crestron lighting modules are compatible with this enclosure?

The CAEN-5X2-MLO-120/2P is designed to house Crestron CLX and CLXI series dimmer modules and relay modules. Confirm specific module compatibility with your Crestron distributor based on your load types and dimming requirements.

How many circuits can this enclosure support?

The enclosure provides 20 breaker slots for branch circuit protection. The number of controllable loads depends on the mix of CLX module types installed, as individual modules may control single or multiple circuits.

Is this enclosure suitable for commercial projects?

Yes. The CAEN-5X2-MLO-120/2P is appropriate for light commercial applications operating on 120V split-phase power, such as small offices, conference rooms, and retail spaces, in addition to residential installations.

Does this enclosure include CLX modules?

No. The CAEN-5X2-MLO-120/2P is the enclosure only. Crestron CLX dimmer and relay modules are purchased separately based on the project’s load schedule and control requirements.
