HL-LD series low temperature circuit breaker

HL-LD series low temperature circuit breakers work in single pole double throw mode. Typical applications include: used to protect heat exchangers, surface coolers and liquid service lines under low temperature conditions to avoid overcooling or freezing. The controller is compact, reliable and features an adjustable temperature set point with fixed hysteresis. When the

temperature of any 200mm long part of the temperature sensing capillary drops to the temperature point set by the dial, the internal switch is turned off. The internal switch is not turned back on until the temperature rises to

more than 4° C higher than the set temperature.
