contacts for low
voltage and low
current
480 V AC and 15 A only upon request
We recommend to use a prefuse of the maximum current rating from the table above according
to the load switched.
We recommend gold plated contacts for all intrinsically safe and other applications with low
voltage/power.
Operating life time
Normal expected service life (expressed in the number of cycles over the full adjustment
range) is appr. 1 million for the pressure switch. This may be extended to 2.5 million cycles
max. if only a part of the adjustment range is used (about 20%).
Switch sensor life may also be effected negatively by:
Media not compatible with the wetted materials.
Too high switch cycling speed or more than 20 cycles per minute.
System cycling pressure exceeding the top of the adjustable range.
