Circuit breaker Chint efficient protection for terminal systems

The circuit breaker is designed to provide reliable protection from overloads and short circuits in low-voltage electrical circuits, particularly in residential and tertiary applications. Thanks to its tripping curve C, it can tolerate inrush currents (such as those from motors or transformers) up to 5-10 times the rated current, preventing unwanted trips.

Compact, standards-compliant design

With standard dimensions and DIN rail mounting (2 modules), this device integrates easily into existing electrical panels. It complies with safety standards and offers impulse withstand up to 4kV, ensuring reliability even in the presence of electrical disturbances.

Expandability and versatility

This model can be accessorized with:

  • AX-X1 series auxiliary contacts (for remote signaling)

  • AL-X1 alarm contacts (for trip alarm)

  • SHT-X1 release coil

  • Minimum voltage coil UVT-X1

  • Not compatible with differential modules

Typical applications

  • Residential electrical systems

  • Distribution boards in commercial environments

  • Terminal systems in light industrial environments

  • Protection of light circuits and outlets from overcurrents
