Siemens 3VA2440-6KQ32-0AA0

The 3VA24 circuit breaker operates within a 3-pole configuration and is rated for 400A with a high breaking capacity of 85kA at 415V, making it suitable for heavy-duty applications. It is designed with an electronic trip unit, specifically the ETU860, which provides advanced overload and short-circuit protection, adjustable from 0.6 to 10 times the rated current for short-circuit settings and 1.5 to 15 times for instantaneous protection.

This unit also supports integrated earth fault protection and is compatible with external current transformers for enhanced protection. The device features IP40 protection and is constructed for built-in mounting techniques, with dimensions of 5.4 x 9.8 x 5.4 inches. The connection for the main current circuit is located at the front side, ensuring easy accessibility.

Additional specifications include a rocker lever control element, optional motor drive capability, and a short-circuit release adjustment range of 240A to 600A. The absence of auxiliary contacts simplifies the design while maintaining robust functionality. This circuit breaker is compliant with IEC standards, making it a reliable choice for various industrial applications.
