Siemens 3RV6011-1KA15

The trip curve is stable, the contacts are resistant to welding, and the arc extinguishing is crisp. The Siemens 3RV6011-1KA15 is made of thick materials. It is brand new and trouble-free. Order directly from Quanzhou Xin Yuan Technology for on-shelf delivery!

Mainframe structure

The Siemens 3RV6011-1KA15 enclosure is compact, with a width of only 45 millimeters. It saves space for the installation of distribution cabinets. The internal arc extinguishing chamber is covered by an arc-blocking plate, preventing the high-temperature gas from spewing out during short-circuit disconnection, thus avoiding any damage to adjacent circuits. The Quanzhou Xin Yuan Technology has disassembled the original components. The bimetallic strip and the electromagnetic trip mechanism fit perfectly. The terminal connection area of the wiring terminals is compatible with 0.5 to 2.5 square hard wires. After compression, pulling it does not loosen. In addition, there is a front rotating handle. After the cabinet door is installed through the hole, the operation is smooth without any jamming. The mechanical life is claimed to be 100,000 times, which is not an exaggeration.

Application fields

Don't use ordinary miniature circuit breakers to handle motor start-up loads. The instantaneous surge directly damages the contacts. This Siemens 3RV6011-1KA15 is originally a motor protection circuit breaker, designed to handle frequent start-up conditions. Equipment like workshop cranes, deep well pumping stations, cooling tower fans with doubled starting currents, it intercepts short-circuit impacts instantly through the electromagnetic trip, and slowly bends the bimetallic strip to disconnect during overload. We have provided single units for water supply projects in the Middle East. The local power grid fluctuates greatly, and it withstands the overheating of the windings caused by voltage drops. It is much more convenient and has a much faster response speed compared to using traditional fuse holders.

Accuracy compliance

The setting current range of the Siemens 3RV6011-1KA15 is 1.6 to 2.4 amperes. The knob scale is as fine as a vernier caliper. For on-site debugging, use a small一字 modification screwdriver for fine-tuning. Align it with the rated value on the motor nameplate， with an error of less than 5%. We have measured it on the quality inspection bench. The delay tripping time of 2.1 amperes is around 12 seconds， and the short-circuit interphase impedance is lower than 10 milli-ohms， with the instantaneous tripping time being less than 4 milliseconds. This accuracy ensures that the windings do not burn out， the auxiliary contacts close and rebound very quickly， and will not give false signals to the PLC input. The interlock control logic is firmly welded.

FAQ module

Q1 Can't turn the adjustment knob?

A1 There is an anti-misoperation locking pin in the factory. You need to pull out the limit pin with a pointed pliers to rotate and adjust.

Q2 How to connect the auxiliary contacts?

A2 The side-mounted module on the left side of the front panel is of the rail-type. The front pins are used for wiring, and there is no need to hollow out the back of the rail for wiring.

Q3 How to inspect the new goods?

A3 Quanzhou Xin Yuan Technology ships with the original factory unopened anti-static film. The batch number on the shell laser marking can be scanned to know for sure from the factory report.
