1SYS273112R0634

The ABB 1SYS273112R0634 Miniature Circuit Breaker (MCB) is a low-voltage electrical circuit protection device from ABB’s System pro M compact SB200M series. It is designed to protect electrical distribution circuits against overload currents and short-circuit faults in residential, commercial and industrial installations.

This model has a rated current of 63 A, a C-type tripping characteristic and a rated short-circuit breaking capacity of 10 kA. The C-curve tripping characteristic makes it suitable for compatible electrical circuits with moderate inrush currents, subject to the characteristics of the connected load and the requirements of the installation.

The circuit breaker incorporates a thermal tripping mechanism for protection against sustained overloads and an electromagnetic tripping mechanism for rapid interruption of short-circuit faults. These mechanisms help protect electrical wiring and connected equipment against damage caused by excessive current.
