Abb Moulded Case Circuit Breaker, 1SDA100424R1, SACE Tmax XT, XT5 S, 3 Pole, 690VAC, 400A, 25kA

The ABB SACE Tmax XT5 S Moulded Case Circuit Breaker (Model: 1SDA100424R1) is a high-performance, compact circuit protection solution engineered to meet the demanding requirements of industrial and commercial power systems. With a rated current of 400A and a rated operational voltage up to 690VAC, this MCCB ensures dependable protection against overloads, short circuits, and electrical faults, enhancing safety and efficiency in low-voltage power distribution networks. This 3-pole circuit breaker comes in a fixed design with front terminals, simplifying installation and ensuring consistent contact pressure and reliability. It is equipped with the advanced Ekip Dip LS/I electronic trip unit, offering adjustable protection parameters for long-time (L), short-time (S), and instantaneous (I) tripping. This provides precise, selective coordination and system adaptability to a wide range of applications and fault conditions. Designed to conform to IEC 60947-2 standards, the XT5 S offers a rated short-circuit breaking capacity of 25kA, making it ideal for medium-level fault current interruption. The breaker also features an 8 kV impulse withstand voltage (Uimp), ensuring resilience against voltage transients and surges.
