Description
ABB S271-K10A Circuit Breaker 10A 1-Pole 230/400V 6kA Din Rail Mount
The ABB S271-K10A is a single-pole miniature circuit breaker (MCB) from ABB's S200 series, rated 10 amps with a K-trip curve. It mounts on standard 35mm DIN rail and provides thermal-magnetic overcurrent and short-circuit protection for branch circuits in industrial control panels, machinery enclosures, and distribution boards. The K-curve characteristic is designed for loads with high inrush currents — such as transformers, solenoids, and motor starting applications — where a standard B- or C-curve breaker would nuisance-trip.

Applications
The ABB S200 series MCB is a standard component in industrial control panels, machine tool enclosures, and building distribution boards across European and international installations. K-curve breakers like this S271-K10A are specifically selected for transformer primary protection, solenoid valve circuits, and other inductive loads where the high start-up current would otherwise cause nuisance tripping with a standard C-curve device. They are commonly used by panel builders, OEM machinery manufacturers, and facilities maintenance teams working with DIN rail-based control systems. The S200 series has been a widely specified ABB product family in both commercial and light industrial wiring applications.
This ABB S271-K10A 1-Pole Miniature Circuit Breaker has been inspected and appears to be in good used condition. The breaker body is clean and shows only light handling wear. The toggle handle moves freely and the DIN rail clip is intact. It was pulled from a working environment where it was previously in service. Please view our photo set and contact us if you have any questions.
