ABB SACE SN250 three-pole molded-case circuit breaker is a 250 amp MCCB intended for three‑phase protection in low‑voltage distribution panels and switchgear. As part of ABB's SN family, the SN250 provides overcurrent protection for all three phases in a single unit, making it suitable for commercial and industrial electrical installations where three‑phase circuits require reliable current limiting and fault interruption. This 3P breaker protects wiring and connected equipment from overloads and short circuits in 250 A circuits.
