Overview
The Burling A-1S-L-169 temperature limit switch is a robust electro-mechanical safety control device designed for critical thermal cutoff applications. This unit is rated for 15 amps at 125/250/480V with a 3-inch probe, making it suitable for direct integration into industrial heating and temperature-critical circuits. The Differential Expansion “DE” product line represents the standard electro-mechanical safety temperature limit switch against which all others are measured, and the Burling design is field-proven across decades of service.
