1SYS252067R0404

The ABB 1SYS252067R0404 is a 2-pole direct current (DC) Miniature Circuit Breaker from the SB200 DC series. It features a current-limiting design incorporating two distinct tripping mechanisms: a delayed thermal tripping mechanism for robust overload protection and an electromechanical tripping mechanism for short-circuit protection. Conforming to IS/IEC 60947-2, it is widely deployed in various residential, commercial, and industrial DC applications such as solar photovoltaic setups, battery storage systems, and heavy-duty DC automation.
