Applications
The ABB S270 series miniature circuit breakers are widely used in commercial and industrial electrical distribution panels, machine control cabinets, and building automation systems. The 2-pole configuration makes this breaker suitable for 240V single-phase or 480V three-phase branch circuit protection where both legs must be switched simultaneously. The K-curve trip characteristic is designed for loads that draw high inrush currents on startup — such as transformers, solenoids, and certain motor loads — distinguishing it from the more common B and C curves used on resistive or standard motor loads. DIN rail mounting allows fast installation and removal in standard European-style and IEC-compliant distribution enclosures, which are common in industrial machinery, HVAC controls, and process automation panels.
This ABB S272-K20A 2-Pole 20A Miniature Circuit Breaker has been inspected and is in good condition. The housing is clean and intact with no visible cracks or damage. The toggle handles move freely and the DIN rail clip appears undamaged and functional. Screw terminals show only minor wear consistent with previous installation use.
