MICROTHERM 52N Series Thermal Switch, NC, 225°C

The MICROTHERM 52N Series Thermal Switch is a reliable and compact safety component designed to interrupt electrical circuits in the event of overheating. It functions as a normally closed (NC) switch, automatically opening the circuit when the ambient temperature reaches its precise switching point of 225°C. This makes it an essential protective device in a wide range of electrical and electronic applications where precise thermal management is critical for safety and equipment longevity.

Once activated, the switch will reset and close the circuit again only when the temperature falls back to approximately 175°C, ensuring the system has adequately cooled before operation can resume. The switch is rated for 125VAC at 15A and 250VAC at 10A, providing versatile compatibility for various control circuits. Its robust construction and reliable operation are housed in a compact, flange-mount sensor housing for easy and secure installation.
