ABB Miniature Circuit Breaker S202UDC-K4A I received this from an acquaintance, but I'm selling it because I won't be using it. I don't know the details, so please be aware of that. *Although it's unused, there are dents and scratches on the box, so please refrain from purchasing if you are sensitive to such things. [Product Description] *Quoted from the website The System pro M compact S200UDC current-limiting miniature circuit breaker is specifically designed for DC applications within the UL489 scope. It has two different trip mechanisms: a delayed thermal trip mechanism for overload protection and an electromechanical trip mechanism for short-circuit protection. It is available in various characteristics (K, Z), configurations (1P, 2P), and rated currents (up to 63A). The short-circuit current rating SCCR acc. UL489 is 14kA. The S200UDC is suitable for DC voltages up to 125 VDC (2-pole). All MCBs in the S200UDC product range comply with UL489 and can be used in commercial and industrial applications.
