ABB SACE SN125 Molded Case Three Phase Circuit Breaker

ABB SACE SN125 is a molded-case circuit breaker (MCCB) designed for three-phase electrical distribution, configured as a 3-pole unit with a rated current of 125 A. Belonging to ABB's SACE family, SN125 provides overcurrent protection for panelboards and switchgear in low-voltage installations, interrupting fault currents in accordance with standard distribution practices and matching the typical busbar layouts used in many switchgear assemblies. The 3-pole construction supports protection of three-phase feeders and downstream equipment in commercial and light-industrial environments where reliable disconnection of fault current is required to maintain system safety and uptime. This SN125 model is intended for integration into distribution boards and assemblies that rely on ABB's SACE MCCB family for consistent performance across similar form factors, enabling straightforward replacement or expansion within existing panel lineups. As with other ABB SACE MCCBs, the SN125 is part of a broader ecosystem of protective devices designed to balance protection, maintainability, and compatibility with standard low-voltage electrical installations.
