ABB 1SDA066711R1 is a Formula A1C 125 moulded case circuit breaker (MCCB) designed for low-voltage electrical distribution and circuit protection applications. It is a fixed, three-pole (3P) MCCB equipped with front terminals and a fixed thermal-magnetic (TMF) release. The breaker has a 25A rated current and a 125A frame size, providing thermal protection against overloads and magnetic protection against short-circuit conditions. The A1C version has a 25 kA short-circuit performance level and is suitable for commercial, industrial and distribution-panel applications. ABB specifies a 690V rated insulation voltage and IEC compliance for this configuration.
