The Klixon 20490 and 20491 series are especially designed for the electric heat, laundry, and other major appliance markets. The high capacity automatic series, (20490 and 20491) are available as limit (L) switches, which open on temperature rise, and fan (F) switches, which close on temperature rise. The switch is enclosed within a phenolic housing and stainless steel cup assembly which protects the contacts from contamination. The stainless steel cup also provides a variety of mounting configurations.

The switch mechanism is actuated by the Klixon snap-action bimetal disc which may be enclosed or exposed. Enclosed disc types should be used in all applications where response to radient heat is not critical as it provides protection (to the bimetal element and switch assembly) against contamination and damage due to handling.
Exposed disc types are used in applications where a faster thermal response to radiant heat is required. Standardized mounting-hole dimensions allow interchangeability with our present 204 and 206 series thermostats.

The 20490 is available with the following terminal configurations: 0.250” X 0.032” flat, 45º, and 90º male quick connect; 0.187” X 0.032” 90º male quick connect; flat and 45º #8-32NC screw terminals.
Only 45º #10-24 screw terminals are available on the 20491.
