Siemens 3VL4140-2PE33-0AA0 VL400 UL ETU LSI Circuit Breaker with Terminals

The Siemens 3VL4140-2PE33-0AA0 is a VL400 UL circuit breaker, specified as a Type JG (cat no. HJX3T400) molded case circuit breaker with a non-interchangeable frame. It holds UL 489 approval for high breaking capacity, featuring a 3-pole design and a NEMA rating of 65kA at 480V. This breaker is equipped with an Electronic Trip Unit (ETU) offering LSI (Long-time, Short-time, Instantaneous) protection, with temperature compensation set at TA=40°C and a rated current (In) of 400A. The adjustable overload protection (IR) ranges from 200A to 400A, short-time delay (ISD) from 1.5 to 10 times IR, and instantaneous trip (II) at 11 times In. A key distinction of this model is that it includes terminals for both feeder and load sides (line and load). Like other spare parts, it is provided without auxiliary release or auxiliary/alarm switches.

This circuit breaker is ideal for line protection in industrial settings where LSI protection is necessary and direct connection terminals are preferred for ease of installation. Its robust construction and high breaking capacity make it suitable for applications in manufacturing plants, processing facilities, and heavy industries requiring reliable overcurrent protection and fault interruption. The integrated terminals simplify wiring and reduce the need for external connectors.
