ABB SACE Formula A2B 250 TMF 250-2500 Circuit Breaker (250A, 3-Pole)

Ensure precise protection for your equipment with the ABB SACE Formula A2B 250. This 3-pole Molded Case Circuit Breaker (MCCB) is rated at the maximum frame capacity of 250A and features a highly reliable thermomagnetic release (TMF) for precise overload and short-circuit protection, with a fixed magnetic trip at 2500A.

Built on the robust A2B 250 frame, this breaker provides a reliable breaking capacity with a 12.5 kA service breaking capacity (Ics) at 240 V AC and 9 kA at 380 V AC. It offers excellent versatility with a rated operational voltage of up to 550V AC and 250V DC, making it an ideal choice for protecting main feeders, motors, and distribution panels where high inrush currents are expected.

Engineered for longevity, it delivers a mechanical lifespan of 10,000 cycles and an electrical lifespan of 4,000 cycles. With front bolt terminals, installation is secure, straightforward, and space-efficient. The 3-pole configuration is ideal for standard three-phase loads. With a low power loss of 16 W per pole, it is also highly energy-efficient.
