1SYS272012R0031

The ABB SB202 M-D3 Miniature Circuit Breaker (MCB), part number 1SYS272012R0031, is a two-pole electrical protection device rated at 3 A with a D-type tripping characteristic and a 10 kA rated short-circuit breaking capacity. It is designed to protect electrical circuits against overloads and short circuits by automatically disconnecting the supply when fault conditions occur. Its thermal tripping mechanism provides overload protection, while its electromagnetic tripping mechanism provides short-circuit protection. The D-curve characteristic makes it suitable for appropriately designed circuits supplying equipment with high starting or inrush currents, such as certain motors and transformers. It belongs to ABB's System pro M compact SB200M product range and complies with the IS/IEC 60898-1 standard. It is intended for suitable residential, commercial and industrial electrical installations, subject to correct circuit design and protection coordination.
