ABB SACE Formula A1A 125 TMF 40-400 Circuit Breaker (40A, 3-Pole)

Ensure precise protection for your equipment with the ABB SACE Formula A1A 125. This 3-pole Molded Case Circuit Breaker (MCCB) is rated at 40A and features a highly reliable thermomagnetic release (TMF) for precise overload and short-circuit protection, with a fixed magnetic trip at 400A.

Built on the compact A1A 125 frame, this breaker provides a reliable breaking capacity for standard commercial and light industrial power distribution systems. It offers excellent versatility with a rated operational voltage of up to 550V AC and 250V DC, making it an ideal choice for protecting control circuits, small motors, and sensitive sub-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 3-pole configuration is ideal for standard three-phase loads. With a low power loss of 4.5 W per pole, it is also highly energy-efficient.
