ABB S281-Z2 Molded Case Circuit Breaker

ABB S281-Z2 is a single‑pole molded case circuit breaker (MCCB) from ABB’s S281 family, designed to protect a single live conductor with a 2 A rated current. It is specified for 277 VAC operation and employs a Z‑character trip curve to provide defined long‑time and instantaneous protection, making it suitable for small‑load circuits within commercial or light industrial panel boards. The unit is engineered for DIN‑rail mounting, allowing straightforward integration into standard distribution enclosures and control panels. With its compact MCCB construction, the S281‑Z2 delivers reliable overcurrent protection for single‑phase circuits while maintaining compatibility with other S281 components and accessories.
