The Siemens 3VL4740-3LB36-0AA0 is a VL400L molded case circuit breaker designed for line protection. It features a very high breaking capacity (Icu) of 100kA at 415V AC and is a 3-pole unit. This breaker is equipped with an electronic trip unit (ETU10) with LI functionality, allowing for an adjustable rated current (In) of 400A and an overload protection setting (IR) from 160A to 400A. The short-circuit protection (II) is adjustable from 1.25 to 11 times the rated current (IN). Notably, this model carries shipbuilding certificates for LRS, DNV, and gL, making it suitable for marine applications. It is supplied without auxiliary releases or switches as a spare part for replacement purposes.

This circuit breaker is ideal for demanding applications in shipbuilding, offshore installations, and heavy industries where extremely high breaking capacity and certifications for harsh environments are required. The ETU10 provides reliable and adjustable protection against overloads and short circuits.
