The 59T and 66T series controls are designed to meet the high electrical capacity requirements of electric water heaters. Both use a temperature sensitive bimetal disc to deliver snap-action to the contacts. The speed and force of contact separation provides long-dependable control life at high
electrical loads.
Features and Benefits
The 59T and 66T series features include:
? Welded construction, used on all internal current-carrying components for greater electrical integrity.
? The 59T mounting tabs snap into the customer's bracket to mount the thermostat on the surface of the tank.
? The trip free manual reset 66T limit control is available with non-adjustable calibrations from 160° to 235°F (71° to 113°C).
? The 59T has an adjustable range of approximately 60°F (33°K). The lowest adjustable limit is 90°F (32°C) and the highest adjustable limit is 200°F (93°C).
? Controls are 100% operation checked.
Switch Actions
The 59T is available in two switch actions:
Automatic reset SPST – The switch opens the normally closed contacts on temperature rise. The contacts automatically return to the closed position when temperatures return to the reset point.
Automatic reset SPDT – This operation is the same as the SPST with the addition of an auxiliary set of contacts, which make circuit upon opening of the normally closed contacts and breaks this circuit upon automatic reset.
