3VA2340-8JQ32-0AA0 SIEMENS

The 3VA2340-8JQ32-0AA0 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 400, indicating its physical size and current carrying capacity. This circuit breaker boasts a high breaking capacity class L, with an ultimate short-circuit breaking capacity (Icu) of 150kA at 415V, ensuring reliable protection against high fault currents. Equipped with an ETU560 electronic trip unit, it offers advanced protection features including LSIG: Long-time, Short-time, Instantaneous, and Ground fault protection. 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, and instantaneous protection (Ii) from 1.5 to 10 times the rated current. N conductor protection is available optionally with an external current transformer, allowing for up to 160% ground fault protection, which can be switched off. Ground fault protection settings (Ig) range 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.
