THERM-O-DISC Non-resettable Circuit temperature limit control 60F & 61F Series,Voltages up to 600VAC

The 60F and 61F line of 3/4” (19mm) bimetal disc temperature limit controls from THERM-O-DISC offer reliable “one shot” operation at temperatures up to 350°F (177°C). Utilizing the same bimetal temperature sensing principle as the 60T automatic reset control, the 60F and 61F permit a uniform approach to the application of temperature limits. Rated for electrical loads up to 25 amps at 600VAC (60F) and 49 amps at 600VAC (61F), these temperature limit controls provide unsurpassed over-temperature protection in a non-resettable design.

Features:

Single operation for reliable, non-resettable, temperature limiting.

Special Kapton insulator for application voltages up to 600VAC.

Snap-action bimetal disc for high-speed contact separation.

The 60F and 61F are single pole, single throw (SPST) switches designed to open their electrical contacts on temperature rise. Once the switch has operated, the unique bimetal “fuse” disc prevents reset of the contacts to their original state at temperatures above -31°F (-35°C). The 60F reflects the same 25 Amp contact rating found in the 60T automatic reset series while the 61F provides a higher current-carrying construction for 49 Amp capability. The Therm-O-Disc 60F and 61F are typically utilized as primary or secondary temperature limits in electric heating equipment.

Terminal Configurations 
Standard terminations for the 60F are .250” x .032” (6.35mm x .81mm) tin-plated brass blades. The 61F is provided with a 10-32 screw and double .250” x .032” (6.35mm x .81mm) blade combination. Optional configurations, which include fork, screw and double blade terminations, are available at additional cost.
