Double pole control opens circuit when pre-set temperature is
exceeded by 15°F when immersed or 30°F if operating in
open air. Must be reset manually.
Change T2 in catalog number to "T2R". 1" and 1-1/4"
NPT items with T2R Control are non-stock.
When maximum amperage is exceeded and external relay is required
(thermostat is used as pilot)Specify T1 thermostat and wire
thermostat to holding coil of relay.
Consult Ogden for alternative size or style terminal enclosures.
