ABB SACE Formula A1N 125 TMF 125-1250 Circuit Breaker (125A, 4-Pole)

Ensure precise protection for your equipment with the ABB SACE Formula A1N 125. This 4-pole Molded Case Circuit Breaker (MCCB) is rated at the maximum frame capacity of 125A and features a highly reliable thermomagnetic release (TMF) for precise overload and short-circuit protection, with a fixed magnetic trip at 1250A.

Built on the compact A1N 125 frame, this breaker provides a high breaking capacity with a 50 kA service breaking capacity (Ics) at 240 V AC and 18 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 8,500 cycles and an electrical lifespan of 1,500 cycles. With front bolt terminals, installation is secure, straightforward, and space-efficient. The 4-pole configuration ensures full protection for both phase and neutral lines. With a low power loss of 11 W per pole, it is also highly energy-efficient.
