Video guide – How to protect a three-phase AC motor? The role of phase and voltage control relays

Both 3-phase and 1-phase electric motors are prone to faults and failures that can result in damage or even destruction of the motor. That is why it is worth using multifunctional devices that ensure the proper operation of the electric motor. We present the CKF-318 phase sequence and loss sensor, the CZF-BT phase loss sensor and the CP-710 voltage relay.
