Description:

The TSH series is a custom designed precision thermal protector with built in self-holding feature. This unique design is environmentally sealed with sophisticated operational properties that allow use in numerous applications particularly tubular heaters. The bimetal disc provides a quick positive break simultaneously activating a PTC heater that enables auxiliary heat to pass through the thermal control preventing reset until the power source is removed. Once power is removed, the PTC is then deactivated allowing the TSH control to cool to a safe pre-defined automatic reset temperature. This device offers unmatched flexibility and has been approved by numerous safety agencies for applications where manual reset is desired without having access to a traditional reset button.

Optional automatic reset with 100,000 cyle rating available.
