ABB AF205-40-11-13 AF Series 4‑Pole Contactor – 110 kW @ 400 V AC (AC‑3), 100–250 V AC/DC Coil, 1NO+1NC

Product Description

The ABB AF205-40-11-13 is a 4-pole IEC contactor from the AF series, designed for motor starting, isolation, by-pass, and distribution applications in industrial automation and power control systems. It is rated 205 A in AC-3 category at 400 V AC, corresponding to a motor power of 110 kW at 400 V, with an AC-1 rating of 350 A for resistive loads and 250 A for UL general use[reference:0][reference:1]. The contactor features an AF-technology electronically controlled coil that accepts a wide control voltage range of 100–250 V AC/DC at 50/60 Hz, managing large voltage variations, reducing panel energy consumption, and ensuring distinct operations in unstable networks[reference:2]. It comes pre-mounted with 1 NO + 1 NC auxiliary contacts and main circuit bars, and includes a mounting kit with all necessary screws, washers, and sockets[reference:3][reference:4]. Typical applications include motor control centers, pump and fan systems, and power distribution panels requiring reliable 4-pole switching.

Standard Features

• 205 A / 110 kW AC-3 Rating: Rated operational current of 205 A in AC-3 category at 400 V AC, suitable for direct-on-line starting of three-phase motors up to 110 kW, with an AC-1 rating of 350 A for resistive loads[reference:5].
• Wide-Range AC/DC Coil (100–250 V): Electronically controlled coil accepts 100–250 V AC/DC at 50/60 Hz, covering standard network voltages worldwide and reducing the number of coil variants required[reference:6].
• Built-in Surge Protection: Integrated surge suppression eliminates the need for external suppression components, simplifying panel design and reducing costs[reference:7].
• 1 NO + 1 NC Auxiliary Contacts: Pre-mounted auxiliary contacts provide integrated signal contacts for status feedback and control interlocking[reference:8].
• 4-Pole Configuration with Main Circuit Bars: 4 NO main contacts with pre-mounted main circuit bars simplify high-current wiring and support 4-pole switching applications[reference:9][reference:10].
• Extended Mechanical Durability: Mechanical service life of 5 million operating cycles ensures long-term reliability in frequent switching applications[reference:11].
• Block-Type Design with Accessories: Compact block design can be easily extended with add-on auxiliary contact blocks and a wide range of accessories for flexible panel integration[reference:12].
