ETU20 electronic trip unit LSI protection Adjustable overload and short-circuit settings 3-pole configuration 55kA breaking capacity

Product description

The Siemens 3VL5763-1SE36-0AA0 is a VL630N series 3-pole air circuit breaker equipped with an ETU20 electronic trip unit for line protection. It offers a standard breaking capacity of 55kA at 415V AC. The trip unit features LSI protection (Overload, Short-circuit In=630A, and Instantaneous), with adjustable overload current (IR) from 252A to 630A and a short-circuit instantaneous setting (II) of 10xIN. This unit is designated as a spare part for replacement purposes.

This circuit breaker is designed for protecting electrical lines against overcurrents and short circuits in industrial power distribution systems. The ETU20 provides adjustable settings for tailored protection, suitable for applications like main feeders, branch circuits, and generator protection where precise overcurrent coordination is required.
