Important parameters of Siemens air circuit breaker 3WL

Circuit breaker specifications:

●Rated current 630A to 6300A;

●3 frame levels;

●3 pole and 4 pole frame;

●The rated working voltage is up to 690VAC and 1000VDC, and the special frame is up to 1000VAC and 1150VAC;

●There are 4 different breaking capacity levels for AC applications, ranging from 55kA to 150kA, and 1 breaking capacity level for DC applications.

Siemens 3WL air circuit breaker is equipped with operating mechanism (manual energy storage operating mechanism with mechanical closing), electronic trip unit and auxiliary contacts (standard with 4 normally open contacts + 4 normally closed contacts) Can be equipped with auxiliary release.

The size difference of Siemens 3WL circuit breaker of uniform size is reflected in the width, which will vary with the number of poles and frame level. In terms of design, the size of the withdrawable circuit breaker depends on the size of the slightly larger withdrawable base.

The circuit breaker has different operating mechanism options:

●Manual energy storage operating mechanism with mechanical closing function;

●Manual energy storage operating mechanism with mechanical and electrical closing;

●Electric operating mechanism with mechanical and electrical closing (standard configuration);

The operating mechanism with electrical closing is suitable for synchronous applications.
