Abb TM24415R Circuit Breaker 150A 3P4W

Product Description

The ABB TM24415R is a 150-amp molded case circuit breaker rated for 3-pole, 4-wire (3P4W) electrical distribution applications. It provides overcurrent and short-circuit protection in commercial and industrial panelboards and switchboards. Rated at 150 amps, this breaker is sized for branch and feeder circuits where reliable fault interruption is required. Licensed electricians and electrical contractors are the primary installers. The 3P4W configuration supports three-phase systems with a neutral conductor, making it suitable for balanced and unbalanced load applications.

This breaker is used in commercial and light industrial electrical distribution systems. It fits into panelboards and switchboards that accept 24CRT-frame molded case breakers. Typical applications include feeder protection for HVAC equipment, motor control centers, and general power distribution in facilities where three-phase service is present. It is not intended for residential load centers.

Key Features

• 150-amp continuous current rating for feeder and branch circuit protection
• 3-pole, 4-wire (3P4W) configuration supports three-phase systems with neutral
• 24CRT frame class for compatibility with matching panelboard and switchboard enclosures
• Provides overcurrent and short-circuit protection per NEC requirements
• Molded case construction for durable service in demanding environments

Compatibility

Designed for use in panelboards and switchboards accepting 24CRT-frame 3-pole molded case circuit breakers. Consult the panelboard manufacturer documentation to confirm frame and interrupting rating compatibility before installation.

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 and lock out the panelboard or switchboard completely before handling or installing this breaker. Verify that the bus bar rating, interrupting capacity, and frame size of the enclosure match the breaker specifications prior to installation. Do not exceed the rated ampacity of the connected conductors.
