Elevator PHASE CONTROL SW11
Phase sequence relay
1.Use phase sequence relay (hereinafter referred to as the relay) is mainly used for the detection of phase sequence or phase protection in the correct phase sequence relay, access to the output; when the phase sequence is incorrect or AC circuit any phase wire, the latching relay.

phase sequence relay SW11
phase sequence protection SW11
under the general phase sequence relay, motor wiring order has already been provided, if for some reason, the phase sequence disorder, the motor will not work even damage. Three-phase power, phase A, B phase, C phase, ABC phase sequence power access motor, the motor is forward, then press the ACB phase sequence power access motor, the motor is reversed. Joined in order to prevent motor reversal phase sequence relay come in power phase sequence to prevent inverting cause the motor to reverse. The phase sequence protection phase sequence relay can be used when the phase sequence circuit with a specified phase sequence does not match the phase sequence relay will trigger action, cut off power to the control circuit so as to cut off the motor power to protect the purpose of motor.
Ordering the elevator phase control
To order the elevator phase control, send the exact model or reference code printed on the original part to [email protected]. Please quote the full code including any suffix so that our team can confirm the correct variant, current stock and lead time before you commit.
About the elevator phase control
Elevator and escalator installations are built around a relatively small number of serviceable assemblies, but they fail at very different rates. The elevator phase control sits in the general elevator & escalator parts group, and it is replaced on a different service interval from the assemblies around it. In practice the failures we see on elevator phase control come down to a small number of serviceable assemblies — the controller, the door operator, the brake, the drive chain and the safety circuit.
Every elevator phase control we supply is inspected before dispatch. Each unit is checked for physical damage, correct marking and the specific wear or degradation patterns that matter for this class of component, then packed to survive international transit. Where a superseded revision is the only one available, we say so plainly and explain the substitution, so the installing engineer can make an informed decision rather than discovering the difference on site.
Buying guidance and compatibility notes
Before ordering the elevator phase control, confirm three things. First, the equipment model, the controller family and the exact reference printed on the failed component. Second, reference numbers change between revisions, so we map the old code onto the current one before quoting. Third, whether the installation is a traction lift or an escalator, since duty cycle and loading differ between the two.
On fitting, one point is worth repeating: a photograph of the nameplate is usually faster than a description, and avoids a return for the wrong revision. Almost every repeat failure we see on elevator phase control traces back to a related component that was left in place, or to an adjustment that was assumed rather than measured.
For buyers comparing suppliers, the elevator phase control is one of the items most often requested alongside the main controller.
Availability of the elevator phase control varies by revision, so it is worth confirming stock before committing to a delivery date.
If you are unsure which variant of the elevator phase control you need, send a photograph of the nameplate and the existing component alongside a description of the fault. That is usually enough for our team to identify the correct replacement without a site visit, and it avoids the cost and delay of returning an incompatible part. We are also happy to advise on the other serviceable items in the same general elevator & escalator parts group, so a planned shutdown can cover several wear items at once.
