Product Short Description
Product Introduction
The ABB A12-30-10-84 is a compact, high-performance 3‑pole AC magnetic contactor from ABB’s A‑Line product family, engineered for reliable switching and control of 3‑phase motors, power circuits, and industrial loads. It features a 110–120 VAC coil (50/60 Hz) and is designed for direct‑on‑line (DOL) motor starting, circuit switching, and load control in industrial automation, manufacturing, and building systems. Built with robust construction and compliant with global safety standards, this contactor delivers consistent performance, long service life, and easy integration into control panels via DIN‑rail or panel mounting. It supports motor control up to 690 VAC and includes a built‑in 1‑NO auxiliary contact for status monitoring and interlocking.
