The 03EN0977, manufactured by NGT, is a hermetically sealed, normally closed (NC) thermal switch designed for temperature-sensitive circuit protection and control applications. This device features a bimetallic snap-action disc calibrated to open the circuit at a nominal temperature of 90°C (±5°C tolerance). The switch body is constructed to withstand environmental stresses and provide reliable operation within specified temperature and vibration parameters. Its 1/2″ form factor refers to the diameter of the switch housing, facilitating integration into various thermal management systems. Upon reaching the specified temperature threshold, the internal contacts separate, interrupting the electrical path until the temperature drops below the reset point (typically 10-20°C below the opening temperature), at which point the contacts automatically reclose. The switch is suitable for applications requiring precise thermal control and over-temperature protection in electronic devices and systems.
