Abb TM24420C Main Breaker Load Center 200A 24-circuit

Product Description

The ABB TM24420C is a main breaker load center designed for three-phase, four-wire electrical distribution in commercial and light commercial applications. It carries a 200-amp main breaker rating and supports a 208Y/120V configuration, making it suitable for systems that feed both 120-volt single-phase and 208-volt three-phase loads. The enclosure is rated for outdoor installation. The unit ships with the main breaker pre-installed, reducing on-site assembly time. A licensed electrician installs and connects this load center as part of a service entrance or sub-distribution assembly.

The TM24420C is used in commercial buildings, multi-tenant properties, and outdoor distribution applications where three-phase power at 208Y/120V is required. It provides 24 spaces for 1-inch breakers, allowing for flexible circuit planning across lighting, HVAC, and general-purpose branch circuits. The pre-installed main breaker enables the installer to de-energize the entire panel at a single point, which is a standard requirement in most commercial service installations.

Key Features

• 200-amp main breaker pre-installed for immediate service
• 24 spaces for 1-inch branch circuit breakers
• Three-phase, four-wire configuration at 208Y/120V
• 10,000 AIC interrupt capacity rating
• Outdoor-suitable enclosure for exposed or weatherproof installations
• Single main breaker provides full panel shutoff for code compliance and safety

Compatibility

Designed as an OEM-style main breaker load center for three-phase 208Y/120V commercial electrical distribution systems requiring a 200-amp, 24-circuit, 3P4W configuration.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the utility feed and verify absence of voltage before making any connections inside the enclosure. The outdoor-rated enclosure must be mounted and sealed per manufacturer instructions to maintain its weatherproof integrity. Do not exceed the panel's 10,000 AIC short-circuit current rating at the point of installation.
