ABB A1N015TW Industrial Magnetic AC Contactor

ABB A1N015TW is a UL-listed molded-case circuit breaker (MCCB) from ABB's Formula family that provides thermal-magnetic protection for low-voltage AC circuits in industrial panels. Available in 1-pole (A1N015TW-1) and 2-pole (A1N015TW-2) configurations, it has a nominal current rating of 15 A and a maximum system voltage of 400 V AC, making it suitable for branch circuits and motor control feeders in industrial environments. The device uses a thermal-magnetic trip unit (TMF) to protect against both overloads and short-circuit faults. Breaker variants are cataloged as A1A015TW (10 kA) and A1N015TW (18 kA), reflecting different short-circuit current ratings, so you can match protection to your system's fault withstand needs. ABB's Formula line emphasizes compact, modular protection in switchgear and control panels, and the A1N015TW accepts standard mounting and termination practices for low-voltage distribution. Typical applications include protecting distribution boards, motor feeders, lighting circuits, and other loads within industrial facilities, where predictable, fast isolation is essential to prevent damage and downtime.
