Abb TM30412C Load Center 125A 3P4W 208Y/120V 30 Space

Product Description

The ABB TM30412C is a 3-phase, 4-wire main breaker load center rated for 125 amps at 208Y/120 volts. It provides 30 spaces for branch circuit breakers, making it well suited for commercial and light industrial power distribution applications where a compact, code-compliant panelboard enclosure is required. The NEMA 1 enclosure rating designates it for indoor, dry-location installation. Licensed electricians and electrical contractors are the primary installers of this equipment. The main breaker configuration allows the panel to be disconnected at a single point, meeting NEC requirements for service disconnecting means in many common application scenarios.

This load center is designed for commercial indoor electrical distribution systems operating on a 208Y/120-volt, 3-phase, 4-wire wye service. Typical installations include light commercial buildings, tenant spaces, and secondary distribution panels fed from a larger switchboard or transformer. The 30-space capacity accommodates a mix of single-pole and multi-pole branch circuit breakers to serve lighting, receptacle, and small equipment loads. The main breaker provides both overcurrent protection and a local disconnect for the entire panel.

Key Features

• 125-amp main breaker provides integral overcurrent protection and a single-point disconnect
• 30 spaces support a full complement of single-pole or multi-pole branch breakers
• 3-phase, 4-wire configuration delivers both 208-volt and 120-volt circuits from one panel
• NEMA 1 enclosure rated for indoor, dry-location use
• 208Y/120-volt system voltage suits standard commercial wye-service applications

Compatibility

Designed as an OEM-style main breaker load center for 3-phase, 4-wire commercial distribution systems operating at 208Y/120 volts. No specific compatible branch breaker families or model numbers were provided in the available product data.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NFPA 70 (NEC) and all applicable local electrical codes. De-energize the upstream service or feeder source completely before working inside the enclosure. Verify that the incoming conductor sizing, conduit fill, and grounding electrode conductor meet NEC Article 230 and Article 250 requirements for the installation. Do not exceed the panel's 125-amp main breaker rating or install breakers beyond the 30-space capacity.
