Siemens 3VA2 IEC Frame 400 LSIG Circuit Breaker | 400A
Siemens 3VA2340-5JQ32-0AA0 3-pole IEC breaker, 400A, 55kA, LSIG.
The Siemens 3VA2340-5JQ32-0AA0 is a 3-pole, 3VA2 IEC Frame 400 circuit breaker with a breaking capacity of 55 kA at 415 V. It features an advanced ETU560 electronic trip unit with LSIG protection, including overload, short-circuit delay, instantaneous short-circuit, and ground-fault protection. The rated current (In) is 400 A, with adjustable overload (Ir) from 160 A to 400 A, short-circuit delay (Isd) from 0.6 to 10x In, instantaneous trip (Ii) from 1.5 to 10x In, and ground-fault settings (Ig) from 0.2 to 1x In with a time delay (tg) of 0.05-0.8s. It supports optional external current transformers for neutral conductor protection up to 160% and can have ground-fault protection switched off. Includes a nut keeper kit.
This versatile circuit breaker is suitable for comprehensive protection in various industrial applications, including main feeders, motor circuits, and power distribution systems where sensitive ground-fault detection is required. Industries include manufacturing, process control, and facilities management.
