£167.89
The ABB S203M-K13NA is a high-performance miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the trusted ABB System pro M compact S200M series, this device delivers dependable circuit protection for residential, commercial and industrial low-voltage installations.
This 13 amp K-curve circuit breaker incorporates delayed thermal overload protection and electromechanical short-circuit protection, helping to safeguard cables, motors, transformers and industrial equipment. Its compact DIN rail design and current-limiting technology enable straightforward installation and reliable long-term operation.
With a rated current of 13 A and a 3P+N configuration, the S203M-K13NA is ideal for three-phase installations requiring neutral switching. The K tripping characteristic is particularly suited to inductive loads with higher starting currents, making it an excellent choice for industrial control systems and machine building.
The ABB S203M-K13NA automatically disconnects electrical circuits during overload or short-circuit conditions, helping protect wiring, motors and connected equipment from damage. Its current-limiting design reduces fault energy and improves system protection.
The K curve characteristic is specifically intended for applications with elevated inrush currents, making this miniature circuit breaker well suited to motor circuits, transformers, solenoids and industrial automation equipment.
