1SYS273012R0981

The ABB SB203M-D0.5 Miniature Circuit Breaker (MCB), order code 1SYS273012R0981, is a three-pole electrical protection device rated at 0.5 A, featuring a D-type tripping characteristic and a rated short-circuit breaking capacity of 10 kA. It is designed to protect compatible electrical circuits against overloads and short circuits using thermal and electromagnetic tripping mechanisms. Its D-curve characteristic provides a delayed magnetic trip response suitable for circuits with specific inrush-current requirements, subject to appropriate circuit design and protection coordination. Part of ABB's System pro M compact SB200M series, this breaker is intended for suitable industrial, commercial and control-panel applications.
