Overview

The ABB S802U-K70 is a 2-pole High Performance Circuit Breaker (HPCB) with a K-characteristic trip curve, rated at 70A and 240/415VAC. This breaker delivers a 50kA interrupting capacity, making it suitable for industrial and commercial applications where high inrush currents are present, such as motor circuits, transformers, and heavy-duty machinery. The K-characteristic ensures rapid response to overloads while allowing brief high-current surges typical in inductive loads. Designed for reliability, the S802U-K70 is part of ABB’s S800U series, known for compact form factors and compliance with international safety standards. Its 2-pole configuration simplifies installation in control panels and switchboards, reducing footprint while maintaining robust protection. The breaker’s 50kA rating at 240/415VAC ensures compliance with stringent electrical codes, providing dependable short-circuit protection. Ideal for facilities requiring precise overcurrent coordination and minimal downtime.
