Based on results in this report, this substance does not have a self-ignition temperature.
Reference
The sample melts between 353°C and 355°C which is shown by the nearly isothermal part of the sample temperature profile at that point. No exothermal self-heating occurred before melting. Immediately after melting the sample in its liquid state decomposes which is evidenced by a temperature increase. After the test nearly all sample had disappeared. This result means that Potassium chlorate did not show self-heating up to its melting point, and consequently this substance does not have a self-ignition temperature.
