Product Description

Product Description
XJ3-D Phase Break and Phase Sequence Protection Relay
  • XJ3 series of phase break and phase sequence protection relays are used for overvoltage and undervoltage, phase break protection and irreversible transmission equipment in three-phase AC circuits. It provides reliable phase sequence protection, featuring stable performance, a wide application range, and ease of use.
  • When connected to the power control loop according to the diagram, the relay performs its protective function. If any phase fuse in the three-phase circuit is open or when the circuit experiences a phase failure, XJ3 acts immediately to cut off the coil power of the AC contactor of the main circuit, thereby protecting the load from phase break damage.
  • For three-phase irreversible equipment, if the phase sequence is incorrectly connected due to maintenance or line changes, the XJ3 series detects the incorrect sequence, stops the power supply circuit, and successfully protects the equipment.

FAQ
Q1. What are the accepted payment terms?
Accepted payment methods include T/T, Western Union, and L/C at sight.
Q2. How is the product quality ensured?
All products undergo strict quality inspection protocols before they leave the factory.
Q3. What are the performance advantages of the products during operation?
The products offer high-quality performance at a competitive price, backed by extensive experience in metallurgical equipment and dedicated professional support.
Q4. What specific protections does the XJ3-D relay provide?
The XJ3-D relay is designed to protect three-phase AC circuits against overvoltage, undervoltage, phase break, and incorrect phase sequence.
Q5. How does the relay react when a phase failure occurs?
In the event of a phase failure or open fuse, the relay acts immediately to cut off the coil power of the AC contactor in the main circuit to protect the load.
Q6. Can the XJ3 series detect incorrect phase connections after maintenance?
Yes, it identifies incorrect phase sequence configurations during maintenance or line changes and automatically stops the power supply circuit to protect the equipment.
