S-ARC1 M B13 Arc Fault Detection Device (AFDD) with MCB – 1P+N – B – 13 A – 10 kA

Why Choose the ABB S-ARC1 M B13 Arc Fault Detection Device?

The ABB S-ARC1 M B13 is a compact arc fault detection device (AFDD) with integrated miniature circuit breaker (MCB) designed to provide enhanced protection for single-phase final circuits. Part of the ABB S-ARC1 M 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 M is designed to protect end-user circuits against earth, parallel and series arc faults as well as overloads and short-circuit currents. By detecting potentially hazardous electrical arcing that a conventional MCB alone is not designed to identify, it provides an additional level of protection against electrical faults associated with damaged conductors, deteriorated insulation and poor connections.

With a rated current of 13 A, a B tripping characteristic and a rated operational voltage of 230–240 V AC, the S-ARC1 M B13 provides a 7.5 kA rated service short-circuit breaking capacity and a 10 kA rated ultimate short-circuit breaking capacity. Its 1P+N configuration and compact construction make it suitable for compatible residential and commercial final circuits requiring enhanced short-circuit performance.

Enhanced Arc Fault and High-Capacity Overcurrent Protection

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

The S-ARC1 M range provides enhanced short-circuit performance, with the S-ARC1 M B13 offering a 7.5 kA service short-circuit breaking capacity and a 10 kA ultimate short-circuit breaking capacity. 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.

Typical Applications

• Residential electrical distribution boards.
• Commercial electrical distribution systems.
• Single-phase final circuits requiring enhanced arc fault protection.
