3VA2440-8JQ32-0AA0 SIEMENS

The 3VA2440-8JQ32-0AA0 is a robust 3-pole circuit breaker from Siemens, designed for line protection in industrial and commercial applications. It falls under the 3VA2 IEC frame 630, ensuring compliance with international standards. This circuit breaker boasts a high breaking capacity class L, with an ultimate short-circuit breaking capacity (Icu) of 150kA at 415V, providing reliable protection against overcurrents. Equipped with an ETU560 electronic trip unit, it offers advanced protection features, including LSIG (Long-time, Short-time, Instantaneous, and Ground-fault) functions. The rated current (In) is 400A, with adjustable overload protection (Ir) ranging from 160A to 400A. Short-circuit protection (Isd) is adjustable from 0.6 to 10 times the rated current, while instantaneous protection (Ii) ranges from 1.5 to 11 times the rated current. N conductor protection is available optionally with an external current transformer, supporting up to 160% ground-fault protection, which can be switched off. The ground-fault protection (Ig) is adjustable from 0.2 to 1 times the rated current, with a time delay (tg) of 0.05 to 0.8 seconds. A nut keeper kit is included for easy installation and secure mounting.
