Crestron CLB-120-20A – Thermal Magnetic Breaker for CAEN-MLO Enclosure, 120V 20A

Product Overview

The Crestron CLB-120-20A is a thermal magnetic circuit breaker rated at 120V/20A for use with Crestron CAEN-MLO automation enclosures that include a load center panel. It provides branch circuit overcurrent protection for individual load circuits wired through the CAEN-MLO enclosure, allowing the enclosure to distribute and protect branch circuits for lighting, shade motors, and other 120VAC loads in Crestron-controlled environments. This breaker installs directly into the CAEN-MLO load center breaker slots.

Product Description

The CAEN-MLO is a Crestron Automation Enclosure variant that incorporates a load center with breaker positions, allowing the control enclosure to serve as both the Crestron module housing and the branch circuit distribution point for the loads the system controls. The CLB-120-20A thermal magnetic breaker installs in the available breaker positions in the CAEN-MLO, providing standard thermal-magnetic overcurrent protection: thermal protection for sustained overloads and magnetic (instantaneous) trip for fault currents. At 120V/20A, this breaker is appropriate for standard branch circuits serving lighting, motor, or receptacle loads within the NEC 80% continuous load rule.

Key Features

• Thermal magnetic overcurrent protection — thermal trip for sustained overloads, magnetic trip for fault currents
• 120V / 20A rating — matches standard NEC branch circuit ratings for lighting and motor loads
• Designed for CAEN-MLO — direct installation into CAEN-MLO automation enclosure breaker slots
• Simplifies installation — combines control system housing and load circuit protection in one enclosure
• Standard breaker form factor — consistent with CAEN-MLO load center design
• Genuine Crestron component — verified compatibility with CAEN-MLO enclosure platform

Typical Applications

• Branch circuit protection for lighting loads in Crestron CAEN-MLO equipped automation enclosures
• Motor circuit protection for shade and drape drives served through CAEN-MLO load centers
• Any 120V/20A branch circuit distributed through a CAEN-MLO enclosure in a Crestron control installation
• Adding or replacing branch circuit protection in an installed CAEN-MLO enclosure

FAQs

Is the CLB-120-20A compatible with CAEN-MLO/2P (split-phase) and single-phase CAEN-MLO enclosures?

Confirm compatibility with your specific CAEN-MLO variant by checking the Crestron CAEN-MLO documentation. The CLB-120-20A is a single-pole 120V breaker; double-pole 240V circuits require a different breaker. Some CAEN-MLO models support only specific breaker types or brands.

Can I use a standard residential circuit breaker instead of the CLB-120-20A in the CAEN-MLO?

Crestron specifies the CLB series breakers for the CAEN-MLO load center. Using non-specified breakers may void the enclosure warranty and could affect UL listing compliance. Use Crestron-specified breakers for CAEN-MLO installations.

Is the CLB-120-20A an AFCI or GFCI breaker?

No. The CLB-120-20A is a standard thermal magnetic breaker only. For arc fault protection, use the CLB-120-20A-AFCI. For ground fault protection, use the CLB-120-20A-GFCI. Verify NEC and local code requirements for which protection type is required for your specific circuit application.
