• This Control: is for continuous operations
is not electronic
has Type 1C action (micro interruption
on operation)
• LVD 73/23/EEC
• EMC 89/33/EEC
For applications with loads between 0.5 and 3.7 Amps,
power factors exceeding 0.65, an anticipated system
switch operation rate of less than once per 2.5 minutes,
and any one cycle greater than 3 seconds on and 3
seconds off.
For applications with loads 0.5 and 38mA, power fac-
tors exceeding 0.65, an anticipated system switch
operation rate of less than once per 5 minutes, and any
one cycle greater than 3 seconds on and 3 seconds off.
Additional suppression may be required for applica-
tions outside these ranges.
