1Current Rating is affected by spring material and lubrication choices. Standard lubrication has a 120°C maximum operating temperature limit.
Use SS springs with no lubrication (-N) for testing beyond standard lubrication temperature limits up to 204°C.
Before using probes near these current limits, please refer to Current Carrying Capacity and Operating Temperature Application Notes.
