Description
The Hager NDN432A is a 32 A, 4-pole, thermomagnetic circuit breaker designed for protecting residential and commercial circuits. Featuring a D tripping curve suitable for high loads (motors, transformers), it offers breaking capacity up to 15 kA (Icu) and 10 kA (Icn).
It is easily installed on DIN rail (4 modules footprint), supports cable cross-sections up to 35 mm² for rigid rail and 25 mm² for flexible cables.
Thanks to its mechanical resistance, a lifespan of 4000 electrical cycles and 20000 mechanical operations, it can be equipped with accessories such as auxiliary contacts, release under voltage and busbar.
