Crestron CAEN-5X1-MLO-120/2P – Automation Enclosure, 5-Module, 20 Breaker Slots, Split Phase

Product Overview

The Crestron CAEN-5X1-MLO-120/2P is a surface or flush wall-mount automation enclosure with 5 module slots, a 20-slot breaker panel, and split-phase 120/240 VAC electrical distribution. It is designed for custom residential and light commercial installations where Crestron CLX-Series lighting control modules must be co-located with the building's branch circuit panel. The enclosure consolidates automation control and electrical distribution into a single, code-compliant cabinet.

Product Description

The CAEN-5X1-MLO-120/2P accepts up to 5 CLX-Series module slots on one side and supports a 20-breaker main lug only (MLO) load center on the other, handling split-phase 120/240 VAC or 120/208 VAC 3-phase at up to 225A. The enclosure is constructed from 16-gauge galvanized steel with a perforated grey steel cover and supports surface or flush wall mounting. Compatible Eaton CHF-series breakers include AFCI, GFCI, and standard types, providing flexible circuit protection options. The enclosure is invertible to accommodate various installation orientations.

Frequently Asked Questions

Q: What CLX-Series modules fit in the CAEN-5X1-MLO-120/2P?
A: The enclosure accepts any standard Crestron CLX-Series module that occupies a single module slot, including dimmer, switch, and universal dimmer modules such as the CLX-2DIM8, CLX-2DIMU8, and CLX-1DIMU4-HP.

Q: Does the CAEN-5X1-MLO-120/2P include a main breaker?
A: No. This is a main lug only (MLO) enclosure, meaning it does not include a main breaker. A main disconnect must be provided upstream by the electrical contractor or utility service.

Q: What is the maximum amperage this enclosure supports?
A: The CAEN-5X1-MLO-120/2P supports up to 225A at the main lugs on split-phase or 3-phase service.
