FREQUENTLY ASKED QUESTIONS

Technical Specifications:

Q: What is the magnetic tripping range specified for the 1492-SP1C060 C-Curve?

A: The magnetic tripping function is designed to activate between 5 and 10 times the rated current (In).

Wiring & Installation:

Q: What is the required tightening torque for the screw terminals to ensure secure wire clamping?

A: The terminals require a tightening torque of 2.5 Newton-meters for both line and load connections.

Troubleshooting & Compatibility:

Q: Does ambient temperature affect the thermal trip characteristic of the 1492-SP1C060?

A: Yes, the reference temperature for the thermal tripping characteristic is 30 degrees C, requiring derating at higher temperatures.
