ABB T4S-250-3P-600V Molded Case Circuit Breaker

ABB T4S-250-3P-600V Molded Case Circuit Breaker is a 3-pole MCCB in the SACE Tmax Tmax T4S family, delivering 250 A of current capacity with a 600 V AC operating voltage. This fixed, molded-case breaker provides thermal-magnetic protection for three-phase feeders in industrial power-distribution panels, interrupting fault currents to guard motors, transformers, and other equipment downstream. Rated for three-phase systems up to 600 V, the T4S-250 model combines a robust molded housing with trip-unit technology to ensure reliable overload and short-circuit protection. As part of the Tmax line, it is designed for integration into standard ABB electrical assemblies and supports common panelboard configurations used in manufacturing facilities, data centers, and processing environments. The 250 A frame size offers appropriate protection for mid-sized feeders while maintaining compact dimensions suitable for space-constrained enclosures. This model is typically selected when a dedicated 3-pole protection device is needed for a 250 A circuit on a 600 V three-phase system, providing dependable protection with straightforward replacement in compatible ABB Tmax T4S installations.
