This snap-action bimetal disc was developed in a ceramic case to handle extremely high temperatures. The new increased
factory calibrated set points are available up to 500¡F (260¡C). The contacts can either open or close on temperature rise.
All models are 100% temperature tested before leaving the factory. Specifications. Electrical Rating: 125 VAC, 15 A,
resistive; 250 VAC, 10 A, resistive 100,000 cycles. Operating Temperature Range: 104¡F-500¡F (40¡C-260¡C).
Differential: 27¡F-90¡F (15¡C-50¡C). Environmental Temperatures: Ð4¡F-554¡F (Ð20¡C-290¡C). Insulation Resistance:
100 M½ or more (with a 500 VDC megger). Circuit Resistance: 50 M½ or less (initial value). Dielectric Strength:
1500 VAC/1 minute.
