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.
