Why Choose the ABB S-ARC1 M B16 Arc Fault Detection Device?
The ABB S-ARC1 M B16 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 single-phase 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 faults associated with damaged conductors, deteriorated insulation and poor electrical connections.
With a rated current of 16 A, a B tripping characteristic and a rated operational voltage of 230–240 V AC, the S-ARC1 M B16 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.
