The Klixon 600 series thermal time delay is a snap–acting relay that performs in any position without contact chatter or noise.

The positive temperature coefficient (PTC) heater element provides voltage compensation over a wide voltage range without danger of overheating at high voltage and assures device actuation under low voltage conditions due to its unique feature of always stabilizing at a specified temperature regardless of ambient temperature or voltage. This will allow the use of a common device over a wide voltage range (example 208V to 277V). Available heater voltages range from 6 volts to 277 volts.

This series incorporates the Klixon snap–action bimetallic disc. This switch and actuating element has proved to be highly reliable since its introduction in 1960. A variety of terminals and mounting plates are available to meet installation requirements of most applications.

The 600 series is available in a variety of capacity ratings.
