Product Description
This miniature circuit breaker is a 1-pole, 10 A device with B-trip characteristic for supplemental protection in control panels and branch circuits. It supports operation up to 480Y/277 V AC and is part of the S200 family designed for compact DIN rail installations. The breaker is current limiting and employs thermal-magnetic trip elements to provide overload and short-circuit response consistent with IEC/EN 60898-1 and IEC/EN 60947-2 frameworks, with UL 1077 recognition for supplemental protection. Rated AC interrupt capability is 6 kA and typical operational ratings include 230/400 V AC per IEC with compatibility for AC/DC low-voltage control applications. The unit features clear contact position indication, bi-directional cylinder-lift terminals, and supports bottom-mount auxiliary accessories to reduce panel space. It is suitable for residential, commercial, and industrial control circuits where fast B-curve tripping and compact DIN 43880 form factor are preferred. The device is identified as S201-B10 within the series and aligns with common installation practices including any mounting position, standardized tightening torque, and wire preparation lengths.
