Why Choose the ABB S402M-K0.5 Miniature Circuit Breaker?

The ABB S402M-K0.5 is a compact, current-limiting miniature circuit breaker (MCB) designed to provide overload and short-circuit protection for low-current circuits in commercial, industrial and critical power distribution systems. As part of the ABB SMISSLINE TP S400M series, it combines dependable two-pole protection with the modular plug-in installation advantages of the SMISSLINE system.

This circuit breaker uses a delayed thermal tripping mechanism for overload protection and an electromechanical tripping mechanism for short-circuit protection. Its Type K tripping characteristic is suitable for compatible inductive loads and circuits where higher starting currents may occur without requiring unnecessary tripping.

With a rated current of 0.5 A, a rated voltage of 240 V AC and a 10 kA short-circuit breaking capacity, the S402M-K0.5 provides precise protection for low-current two-pole circuits. Its SMISSLINE TP plug-in design enables straightforward integration into compatible ABB modular distribution systems.

Reliable Protection for Low-Current Industrial Circuits

Miniature circuit breakers such as the ABB S402M-K0.5 protect electrical wiring and connected equipment against excessive current. A delayed thermal tripping mechanism responds to sustained overload conditions, while electromechanical tripping provides rapid disconnection during short-circuit faults.

The combination of a low 0.5 A rating and Type K characteristic makes the S402M-K0.5 particularly useful for compatible low-current circuits where inductive loads or starting currents must be accommodated. Its two protected poles and SMISSLINE TP plug-in architecture make it a practical protection device for control, automation and industrial distribution systems.

Typical Applications

  • Industrial control and automation panels.
  • Low-current control circuits.
  • Instrumentation and monitoring circuits.
  • Compatible inductive loads with higher starting currents.
  • Machine control and auxiliary circuits.
  • Commercial and industrial electrical distribution systems.
  • SMISSLINE TP modular distribution systems.
