ABB T1N-D100 Molded Case Circuit Breaker MCCB

ABB Tmax T1N-D100 Molded Case Circuit Breaker MCCB is a 100 A, 3-pole device from ABB's Tmax family, designed to protect electrical distribution circuits from overcurrent and short circuits. It employs a magnetic-only trip mechanism (MCS) for fast interruption, ensuring rapid fault clearance in feeders and panelboard circuits. The T1N-D100 variant carries an interrupting rating of 50 kA at 240 V AC, making it suitable for medium fault currents in commercial or light-industrial installations. Marketed in a quick-ship configuration, this MCCB integrates with ABB's Tmax ecosystem and is compatible with standard MCCB accessories for straightforward installation and coordination with upstream protective devices. Typical applications include protection of branch feeders, motor control centers, switchgear feeders, and other low-voltage distribution equipment where reliable protection and consistent trip characteristics are required.
