Siemens 3WL1350-4AA46-5FA4 SENTRON 3WL withdrawable non-trip unit circuit breaker

Product Positioning

The 3WL1350-4AA46-5FA4 belongs to the Siemens SENTRON 3WL series Size III withdrawable circuit breaker. The circuit breaker itself does not contain an overcurrent trip unit and is functionally a non-automatic type (isolating switch), which is different from the protection type circuit breaker equipped with an ETU trip unit.

Core Product Advantages and Features

Non-automatic design

The main body does not include an overcurrent protection trip unit (no ETU) and is mainly used as a switch for circuit isolation or in conjunction with external protection devices.

Pull-out trolley structure

It adopts a withdrawable structure and can be pulled out as a whole with a guide frame, which facilitates maintenance and repair work during power outages.

4. Extremely high current applications

Designed with 4 poles and a rated current of 5000A, this is suitable for main circuit disconnect switches in power distribution systems with a neutral line.

High mechanical segmentation capability

The rated ultimate short-circuit breaking capacity Icu is approximately 100kA (500V), and it has good mechanical breaking and withstand capabilities.
