✅ Matches OEM specifications for part numbers W58-XB1A4A-30 and 1-1393249-6 delivering direct drop-in replacements.
✅ Works as a handy swap-in unit for Siemens, TE Connectivity, and Potter&Brumfield thermal breaker assemblies.

💡 What causes a thermal circuit breaker to trip in industrial control panels?

Thermal circuit breakers trip automatically when sustained current flow generates excess heat beyond rated limits, signaling potential equipment strain.

- Responds to prolonged overload conditions by sensing thermal expansion in bimetal elements to interrupt power before wiring insulation melts or fails.
- Protects motor drives and control relays in 250V AC or 50V DC configurations by cutting current when load exceeds the 30 amp safety threshold continuously.
- Resets cleanly with the push switch feature after the underlying issue resolves, restoring normal function without needing part replacement for nuisance trips.
