ABB T3N175TW Molded Case 3-Pole Circuit Breaker

ABB T3N175TW is a three-pole, thermal-magnetic molded-case circuit breaker from the Tmax T3 family, rated at 175 A to protect three-phase feeders in industrial panels. It provides overload and short-circuit protection with a 25 kA interrupting capacity at 480 VAC and is rated for up to 500 V DC, making it suitable for mixed AC/DC environments. The device is built in ABB’s A-frame molded-case format and carries the part number T3N175TW, reflecting its standard 3P MCCB configuration for three-phase systems. In typical panel installations, this breaker protects motors, drives, and distribution circuits by quickly interrupting fault currents, while offering stable thermal-magnetic tripping that responds to both sustained overloads and short circuits. With a compact footprint within the Tmax T3 line, the T3N175TW is widely used in industrial control panels and switchgear where reliable protection for 3-phase circuits at 480 VAC is required, and where a robust 25 kA short-circuit capability provides a margin for safety and system reliability in moderately powered applications.
