Abb tm3215ccu 150A 32-circuit Main Breaker Load Center

Product Description

The ABB tm3215ccu is a PowerMark Gold main breaker load center designed for single-phase, 3-wire residential electrical distribution systems. Rated at 150 amps with a 22kA interrupting capacity (IC), it accepts up to 32 single-pole breakers sized at 1 inch. The copper bus construction ensures reliable conductivity and long-term durability. A factory-installed main breaker provides a single point to de-energize the entire panel, streamlining both initial installation and routine service. This load center is appropriate for licensed electricians performing new construction or panel replacement work in residential applications.

The tm3215ccu is suited for residential service entrance and distribution applications operating at 120/240 volts, 1-phase, 3-wire. The combination surface and flush enclosure design gives the installing electrician flexibility to mount the unit in standard stud-bay flush installations or surface-mount it on finished walls, reducing the need for rework on retrofit jobs. With 32 circuit spaces, the panel accommodates typical whole-home branch circuit loads including HVAC, kitchen, laundry, and general lighting circuits.

Key Features

• 150A bus ampere rating supports full residential service entrance loads
• 32 spaces for 1-inch single-pole breakers
• 22kA interrupting capacity (IC) for fault protection
• Copper bus bar for reliable conductivity and reduced resistance
• Factory-installed main breaker for immediate de-energization of all branch circuits
• Combination surface and flush enclosure mounting for installation flexibility

Compatibility

Designed as an OEM-style replacement or new-install load center for residential single-phase 120/240-volt electrical distribution systems requiring a 150A main breaker panel with 32 circuit spaces.

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 service at the meter before beginning any wiring work — the main breaker does not isolate the line-side lugs. Verify conductor sizing and conduit fill meet NEC requirements for the service ampacity before terminating wires. Inspect the enclosure knockout locations before mounting to confirm alignment with incoming conduit runs.
