Abb TM24415C Circuit Breaker 150A 3P4W

Product Description

The ABB TM24415C is a molded case circuit breaker rated at 150 amps for 3-pole, 4-wire electrical distribution systems. It provides overcurrent and short-circuit protection in commercial and industrial panel applications. The 24CRT frame designation indicates the breaker's series and interrupting capacity class, making it suitable for branch or feeder circuit protection. Licensed electricians install this breaker during new construction, service upgrades, or panel retrofits where code-compliant overcurrent protection is required.

This breaker is intended for 3-phase, 4-wire distribution systems typically found in commercial buildings, light industrial facilities, and multi-tenant electrical services. The 3-pole configuration handles all three line conductors simultaneously, and the 4-wire rating accommodates a neutral conductor in the circuit path. It fits loadcenters and switchboards designed to accept the 24CRT frame series.

Key Features

• 150-amp continuous current rating for feeder and branch circuit protection
• 3-pole configuration interrupts all three phases simultaneously on a fault
• 4-wire design accommodates neutral conductor in the distribution path
• 24CRT frame series construction for compatibility with matching enclosures and panels
• Molded case design provides durable overcurrent and short-circuit protection

Compatibility

Designed as an OEM-style replacement or direct-install molded case circuit breaker for 3-pole, 4-wire electrical distribution panels and switchboards accepting the 24CRT frame series.

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 panel before handling or installing the breaker. Verify that the panel or switchboard is rated to accept the 24CRT frame series before installation. Do not exceed the breaker's 150-amp continuous current rating in the final circuit design.
