Siemens 3RW3027-1BB14

The compressor of the refrigeration unit got stuck and tripped due to power failure? Use Siemens 3RW3027-1BB14, which has a soft start and current limiting function. Quanzhou Xinyuan Technology offers low price and discounts. Just connect and it will operate normally!

Original Characteristics

The Siemens 3RW3027-1BB14 is essentially a soft starter designed to provide a gradual and smooth start for motors. It is far superior to a rough and direct contactor. The phase angle of the thyristors in this device has a very stable slope, and it strictly limits the starting current to within three times the normal value. This ensures that the pumping station pipeline network is no longer prone to water hammer bursts, and the belt conveyor will no longer break due to sudden tensile force. After inspecting the casing, we found that the anti-moisture coating of the paint was thoroughly applied, and the terminal copper strips were thick. It can withstand the conductive dust and humid heat environment in the workshop. The physical protection at the bottom is very strong, and the refurbished board cannot achieve this factory condition.

Highlight Analysis

The wiring logic of the Siemens 3RW3027-1BB14 is extremely simple. The main circuit has incoming and outgoing lines, and the control terminals are designed for plug-and-play. There is no need to screw the screws by hand; simply press and pull to save effort. It has built-in motor overload and phase failure protection. When the circuit trips, the fault code can be read directly on the panel. The wiring is not confusing. The initial voltage and rise time can be set by the knob, and on-site debugging can be completed in two minutes with a small screwdriver. We have modified an old air compressor cabinet with this model. The original system logic was not modified at all, and after the bypass operation, the temperature rise was extremely low. The reason for purchasing this model is the simplicity of debugging and the excellent anti-interference performance, which saves money and time.

Ultra-fast Delivery

Waiting for materials to arrive is the most costly. These Siemens 3RW3027-1BB14 are currently lying in our temperature-controlled and anti-static warehouse. The rust-proof vacuum bag has never been opened or sealed, and it comes with the factory test report and original factory certificate. Each unit is packed with high-density shockproof pearl cotton, and the outer box is equipped with a wooden frame. For large-scale projects requiring goods, the order is directly sent to the workshop for selection.

FAQ module

The panel shows F3 has a problem. What's wrong with it?

It's a phase missing. Use a meter to measure the terminals of the incoming lines L1, L2, and L3, and see which wire is disconnected and has burned black.

How to connect the external bypass contactor?

The soft start unit has dry contacts inside. Once the start is completed, it will automatically close. Just pull the coil to control it directly.
