Asea Brown Boveri Ltd AL9Z-30-10-15 Contactor

ABB AL9Z-30-10-15 Contactor is a three-pole, non-reversing line contactor from ABB’s AL9Z family, designed to switch three‑phase loads with a 24 V DC coil. It features 3 main normally open contacts and 1 auxiliary normally open contact, with a rated auxiliary circuit voltage up to 690 V and a rated supply frequency of 50–60 Hz. The device carries a conventional free‑air thermal current Ith of 16 A and is rated for an operational current of Ie 25 A under AC‑1 (690 V) and Ie 9 A under AC‑3 (230 V, 55 °C), with an AC‑3 power rating Pe of 2.2 kW at 230 V. It offers a rated breaking capacity of 8 × Ie and a rated making capacity of 10 × Ie for AC‑3, and an AC‑15 Ie of 4 A at 230 V for control‑circuit loads. Coil consumption is approximately 3 W (holding) for the DC coil, enabling low‑power drive from standard control electronics. This contactor is commonly used to energize and protect 3‑phase motors and other high‑power loads up to 690 V AC, delivering reliable switching in industrial control panels where compact three‑pole construction and defined contact ratings are essential.
