ABB 2CDS253001R0427-S203-K10 Molded Case Circuit Breaker

ABB S203-K10, catalog number 2CDS253001R0427, is a three-pole molded-case circuit breaker (MCCB) from ABB’s S200 family designed for low‑voltage distribution panels. It is rated for 10 A and 230/400 V AC operation, with a K‑type thermal‑magnetic trip that provides overload and short‑circuit protection for three‑phase circuits. The unit is DIN‑rail mountable for compact, modular panel installations and offers a short‑circuit breaking capacity of 6 kA at 400 V, making it suitable for branch‑circuit protection in light industrial and commercial equipment where reliable overcurrent protection is required. This S203‑K10 variant, identified by the 2CDS253001R0427 part code, is designed to coordinate with other protections in multi‑breaker panels and is typically used where prompt response to overcurrent conditions on three‑phase lines is needed without increasing overall panel size.
