1SDA067618R1

ABB 1SDA067618R1 is a high-performance SACE Tmax XT2H series molded case circuit breaker designed for reliable protection, isolation, and switching of low-voltage electrical distribution systems. The device features a 160 A frame size, a 32 A rated current, and four poles, making it suitable for three-phase electrical systems with neutral protection and switching requirements. The circuit breaker is equipped with a thermomagnetic TMD trip unit. The thermal protection is adjustable from approximately 22.4 A to 32 A (0.7–1 × In), providing protection against prolonged overload conditions, while the fixed magnetic protection responds rapidly to high short-circuit currents.
