ABB A1N020TW-1 Low-Voltage AC Contactor Industrial Grade

ABB A1N020TW-1 is a two‑pole molded‑case circuit breaker (MCCB) from ABB’s Formula family, engineered for industrial low‑voltage power distribution. It provides overload and short‑circuit protection with a thermal‑magnetic trip, and it uses front‑terminal connections for straightforward panel installation. The TW‑1 variant is the 20 A version in the A1N/A1A TW lineup, designed to protect circuits in control panels, motor starter assemblies, and general industrial distribution gear. It offers a short‑circuit breaking capacity up to 25 kA at 240 VAC and 10 kA at 250 VDC, delivering reliable fault protection across typical industrial fault conditions. With its compact, front‑terminal design and compatibility within ABB’s Formula MCCB ecosystem, the A1N020TW‑1 is well suited for modular protection schemes where precise current rating, predictable trip behavior, and easy replacement are important. This model is intended for use in demanding environments where clear protection boundaries and quick, safe disconnection are essential for downstream equipment and operators.
