Why Choose the ABB S-ARC1 B6 Arc Fault Detection Device?

The ABB S-ARC1 B6 is a compact arc fault detection device (AFDD) with integrated miniature circuit breaker (MCB) designed to provide enhanced protection for single-phase final circuits. As part of the ABB S-ARC1 series, it combines arc fault detection with thermal-magnetic overload and short-circuit protection within a single two-module DIN rail device.

The S-ARC1 is designed to protect end-user circuits against earth, parallel and series arc faults as well as conventional overloads and short-circuit currents. Integrated AFDD indication and internal testing functionality assist with monitoring the device while providing an additional level of protection against electrical arcing that a conventional MCB alone is not designed to detect.

With a rated current of 6 A, a B tripping characteristic and a rated operational voltage of 230–240 V AC, the S-ARC1 B6 is designed for 1P+N single-phase circuits. It provides a 6 kA rated service short-circuit breaking capacity and a 7.5 kA rated ultimate short-circuit breaking capacity, making it suitable for compatible residential and commercial final circuits.

Key Advantages

  • Combines arc fault detection and MCB protection in one compact device.
  • 6 A rated current with B tripping characteristic.
  • Protects against earth, parallel and series arc faults.
  • Integrated thermal-magnetic protection against overloads and short circuits.

Enhanced Arc Fault and Overcurrent Protection

Arc fault detection devices monitor electrical circuits for characteristic conditions associated with potentially dangerous electrical arcing. The ABB S-ARC1 is designed to protect against earth, parallel and series arc faults while its integrated miniature circuit breaker provides thermal-magnetic protection against overloads and short-circuit currents.

Combining AFDD and MCB functionality within a compact two-module device helps simplify distribution board design while providing protection against electrical faults that conventional MCBs alone are not designed to detect. The S-ARC1 series also incorporates AFDD indication and internal testing functionality to support dependable protection and straightforward fault diagnosis.

Typical Applications

  • Residential electrical distribution boards.
  • Commercial electrical distribution systems.
  • Single-phase final circuits requiring enhanced arc fault protection.
  • Circuits protected at 6 A requiring a B tripping characteristic.
  • Lighting and compatible low-current final circuits.
  • Installations where enhanced protection against electrically initiated fires is required.
  • Installations requiring combined arc fault, overload and short-circuit protection.
