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.
