The ABB 1SBL177001R1310 is an industrial 3‑pole AC contactor from ABB’s AF16 series, designed for switching and controlling three‑phase power circuits such as motors and general loads.It features a compact block‑type design with a wide‑range control coil (100–250 V AC/DC) that accommodates both AC and DC control voltages without requiring a specific coil version. The contactor includes a built‑in auxiliary contact, robust screw terminals, and integrated surge protection, making it suitable for reliable operation even in environments with unstable control voltages. It is commonly used in motor starters, control panels, and automation systems for industrial and commercial applications.
