Features:
- The magnetic trip principle is coordinated with external current transformers for high-current motor circuits.
- The official selection table assigns the 146-to-230 A band, 250-to-800 A transformer range and 315 A scale reference to RM1XA315.
- The non-latching reset form and M10 terminal arrangement must be retained during an exact replacement.
A TeSys magnetic overload relay for high-current motor protection using external current transformers. The RM1XA315 selection table covers a 146 to 230 A operating band with 250 to 800 A transformer primary ratings and a 315 A scale reference; it is the non-latching form and must not be confused with RM1XA3151. Selection must preserve the complete label identity, connected-equipment compatibility and manufacturer installation limits.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Confirm the current-transformer primary rating, secondary interface and the 146-to-230 A relay setting range as one protection combination.
Keep RM1XA315 separate from RM1XA3151; the final digit changes the latching behavior and control sequence.
After wiring and torque checks, carry out the approved injection or functional trip test and confirm reset and auxiliary-contact operation.
