製品紹介

XJ12 Three-Phase Sequence Protection Relay

A compact DIN-rail phase-sequence relay for matched three-phase control circuits. The narrow front panel provides Normal and Alarm indications, with input and relay-contact terminals at opposite ends. Match the complete relay version, sensing supply and contact duty to the equipment circuit.

Before Ordering

  • Compare full model/version, three-phase sensing supply, contact duty, mounting clearance and terminal arrangement.
  • Confirm any required under/over-voltage or unbalance function by exact suffix; do not assume these functions from the base XJ12 name.
  • Qualified electrical personnel must isolate, wire and function-test the relay in the complete control circuit. Follow the original terminal diagram, not a photograph alone.

Frequently Asked Questions

Does XJ12 include all XJ3-D or XJ3-G functions?

No. The base XJ12 selection monitors phase loss and phase sequence; additional functions depend on the exact relay version.

Is 250 VAC / 3 A the relay's sensing supply?

No. It describes a relay-contact duty reference. The sensing supply is a separate selection.

Can a similar relay be substituted by matching the housing?

Compare full model, required functions, sensing voltage, terminal arrangement and contact duty before replacement.

Does the comparison table change the ordered item to XJ3?

No. XJ12 remains the selection here; choose any related version explicitly when ordering.
