The 388 true off timers are square base, bladed products. Solid state circuitry combined with a magnetic latching relay allow this product to time when no power is applied. Contacts transfer when power is applied. Timing begins when power is removed. Contacts return to the home position at the end of the timing cycle. No external control switch is needed to initiate timing. The package on this series is typically socket mounted.

Additional contact configurations and coil options are available – please use the RFQ/RFI tab above to submit your request.
