Why Choose the ABB S203-K1.6 Miniature Circuit Breaker?
The ABB S203-K1.6 is a compact and reliable 3-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. Part of the ABB System pro M compact S200 range, it provides dependable modular protection for commercial, industrial and control panel applications.
With a K tripping characteristic, the S203-K1.6 is suited to circuits with higher inrush currents, helping to reduce nuisance tripping while maintaining effective protection. This makes it a practical choice for selected motor, transformer, inductive load and automation circuits.
Rated at 1.6 A with a 3-pole configuration and 6 kA short-circuit breaking capacity, the ABB S203-K1.6 provides reliable protection for three-phase circuits in a compact DIN rail format. Its current-limiting design helps improve safety by reducing fault energy during short-circuit conditions.

Reliable Protection for Low-Current Three-Phase Circuits
Miniature circuit breakers such as the ABB S203-K1.6 automatically disconnect a circuit when excessive current is detected. The thermal trip mechanism provides overload protection, while the magnetic trip mechanism responds quickly to short-circuit faults.
The K curve characteristic is designed for circuits where inrush currents may occur during normal operation. This helps make the S203-K1.6 suitable for selected inductive loads, control circuits and automation equipment where standard tripping characteristics may be less appropriate.
Typical Applications
- Three-phase control circuits.
- Industrial automation panels.
- Transformer and inductive load protection.
- Machine building and OEM equipment.
- Commercial and industrial distribution boards.
- Low-current motor and auxiliary circuits.
