The ABB XT4S 250 TMA 250-2500 FF 3P is a high-performance molded case circuit breaker from the SACE Tmax XT series, designed for reliable protection and control in industrial and commercial power distribution systems. With a 250A frame and a thermal-magnetic trip unit providing adjustable overload protection (175–250A) and adjustable magnetic short-circuit protection (1250–2500A), it offers precise coordination and flexible protection settings. The breaker delivers an ultimate breaking capacity of 85kA at 220–240V AC, 50kA at 380–440V AC, and 12kA at 690V AC, ensuring robust fault current interruption. Its fixed three-pole design with front bolt terminals and compact dimensions (105mm W × 160mm H × 82.5mm D) make it ideal for panel builders seeking a space-efficient, high-reliability solution. Compliant with IEC 60947-2 and carrying marine approvals (LR, GL, BV, RINA, DNV, RMRS, ABS, NKK), the XT4S is suitable for a wide range of industrial, commercial, and marine applications worldwide.

  • Adjustable Thermal-Magnetic Trip Unit (TMA): Thermal overload protection adjustable from 175A to 250A (0.7–1 × In) and magnetic short-circuit protection adjustable from 1250A to 2500A (5–10 × In), providing precise coordination and flexible protection settings.

  • High Breaking Capacity: Delivers 85kA Icu at 220–240V AC, 50kA at 380–440V AC, and 12kA at 690V AC for reliable fault current interruption across diverse voltage levels.

  • Compact & Robust Design: Space-saving dimensions of 105mm × 160mm × 82.5mm (W × H × D) with a durable molded case, suitable for panel mounting in space-constrained enclosures.

  • Front Bolt Terminals (FF): Fixed front-terminal design ensures secure and low-resistance terminations for high-current wiring, simplifying installation within switchboards and distribution panels.

  • High Mechanical & Electrical Durability: Mechanical life of 25,000 operations and electrical life of 8,000 operations (at 120 cycles/hour) ensure long-term reliability in demanding applications.

  • Wide Operating Voltage Range: Rated for operation on systems up to 690V AC and 500V DC, suitable for global industrial and infrastructure applications.

  • Global Approvals & Marine Certifications: Compliant with IEC 60947-2 and CE marked; certified by Lloyd’s Register, Germanischer Lloyd, Bureau Veritas, RINA, Det Norske Veritas, RMRS, ABS, and NKK for marine use.
